Frequently Asked Questions (FAQ)

This version dated May 2016. Please note that the information on this page is intended to give a general overview. There may be exceptions to the answers for journals published on behalf of partner organizations. In addition, there may be variations due to specific publishing requirements for the research community represented by the journal. If in doubt, please check the journal homepages or contact permissions@iop.org. FAQs webpage contents The following areas are covered on this page. Please click to go to the relevant section below to see all the FAQs.

COPYRIGHT

For information on copyright, please refer to our main Copyright page. Some journals also have their own copyright page containing useful information, which can be found from the copyright link in the journal links on the right of the journal homepage or from links on the main Copyright page.
  • How does copyright protection work? Copyright protection applies automatically to any original work as soon as it is written down or put into permanent or fixed form. There does not need to be a © symbol next to the work for it to be protected by copyright. It generally lasts for 70 years after the death of the author (or the last remaining co-author). Therefore, just because the work is old, does not mean that it is not protected by copyright.

GOLD OPEN ACCESS

    • What is Creative Commons licensing? Creative Commons is a non-profit organization that has released several open access licences, known as Creative Commons Licences, free of charge to the public. The licences grant rights to the users of the content but do not replace ownership of the copyright, which remains with the copyright owner. You can read more about the licences on the Creative Commons website.
 
  • What is gold open access? For information on gold open access, please refer to our main Open Access page, and also to each journal's open access information pages, where applicable, which can be found from the open access link in the journal links on the right of the journal homepage.

USE OF THIRD PARTY CONTENT IN IOP JOURNALS

Use of figures
    • Do I need to obtain permission to use figure(s) taken from prior publications in my article? Yes. If you did not create the figure(s) yourself for use in this article, then it is likely that it is protected by copyright. You must seek the permission of the copyright owner to include it within the article. The copyright owner is usually the publisher of the content, although this should be checked as sometimes authors retain ownership of the copyright in their articles.Even if you are the creator of the figure(s) taken from your previous publication, if you transferred ownership of the copyright (assigned) or exclusively licensed the copyright to the publisher as part of the article publication process, then you will need to obtain permission. In those circumstances, it is likely that the copyright is controlled by the publisher.A few publishers allow authors to reuse their own content from their previously published articles without permission. You should check the permissions/reuse policy of the particular publisher before doing so.
 
    • Do I need to obtain permission to use a figure I have adapted from a previously published figure? Yes. Generally adapted figures require the permission of the copyright owner of the figure which you have adapted. You only do not require permission, if the figure you have created is so different to the original figure that it is no longer recognisable (this is judged on a qualitative not a quantitative basis). Changing the font, colour or size of the figure, or only using part of it, still requires permission.
 
    • How do I obtain permission to use figure(s) from third party publishers? You should first check whether the publisher is a signatory to the STM Permissions Guidelines 2014 (the "Guidelines"). This is an agreement between STM signatory publishers which allows re-use of small numbers of figures and small amounts of text of one signatory publisher in journal articles, published by another STM signatory publisher, free of charge. IOP Publishing is a signatory to the Guidelines.If the publisher in question appears in the first, "automatic process" column of the Guidelines, then you do not need to seek permission for use compliant with the Guidelines. If the publisher is listed in the second, "Notification required" column of the Guidelines, then compliant use will be permitted free of charge, but permission must nevertheless be sought from the STM signatory publisher. If use of the figure(s) or text exceeds the amount of reuse the Guidelines allow, then express permission must always be obtained from the STM signatory publisher (but they should grant the number of figures allowed within the Guidelines free of charge). Make sure you notify them that the content will be reused in an article published by another STM signatory publisher, IOP Publishing.If the publisher is not a signatory to the Guidelines, then you are likely to need permission. Some publishers have policies, which allow authors to reuse content from their own articles without permission, but you need to check the specific policy of the publisher concerned.If permission is required, you may be able to gain the consent of the publisher via the RightsLink service (many publishers now use RightsLink, most having a direct link to this service from the article); otherwise you should contact the publisher direct. Depending on the publisher's policy, you may also need the permission of the author. If the publisher doesn't use RightsLink, the permission request form can be customised for use when making direct requests to publishers and all responses should either be uploaded via the author centre, or emailed to the relevant journal mailbox, along with the manuscript ID number.
 
    • How many figure(s) am I allowed to use under the STM Permissions Guidelines? The STM Permissions Guidelines 2014 allow an STM signatory publisher with respect to a particular journal article or book being prepared for publication:
      • use of up to three figures (including tables) from a journal article or book chapter, but:
      • not more than five figures from a whole book or journal issue/edition;
      • not more than six figures from an annual journal volume;
      • not more than three figures from works published by a single STM signatory publisher for an article; and
      • not more than three figures from works published by a single STM signatory publisher for a book chapter (and in total not more than thirty figures from a single STM signatory publisher for re-publication in a book, including a multi-volume book, with different authors per chapter)
      Remember, depending on which basis the publisher signed up to the Guidelines, you may still need to request permission (see FAQ above).
 
    • Do I need to obtain permission to use figure(s) which have not been published before? If the figure(s) are unpublished, the copyright is likely to be owned by the author, whose permission will be required.If you created the figure(s) which are unpublished, and did not create them as part of your job, then you should not need to request permission. However you need to check the terms of any contract you may have with any third party relating to the creation of any copyrighted works.
 
    • I have downloaded a figure/photo from the internet. Do I need permission to use it? Permission should always be requested from the copyright owner of any figure or photograph taken from the internet before it is used elsewhere. You should supply full details of the planned re-use when sending your request to the owner of the copyright. Just because there is no © symbol next to the figure or photograph does not mean that permission is not required. Figures/photographs made available on the internet are available to look at but are not automatically available to reuse, unless legitimately made available (i) in the public domain or (ii) on a gold open access basis by the copyright owner under an open access licence which allows for commercial reuse.
 
    • Can I use figures/content from subscription articles in my article which is going to be published under the gold open access model? When seeking permission, you should make it clear that the article will be published under the gold open access model (and under which type of licence). If permission is granted, take care to include a © notice adjacent to the figure/content, in the form requested by the copyright owner, to ensure that it is clear to readers that the figure/content is not included in the gold open access re-use licence.
   
    • Do I need to obtain permission to use figure(s) from an article which was published under the gold open access model, under one of the Creative Commons Licences? If the figure(s) you wish to use were published in an article which was published under the gold open access model, for example under one of the Creative Commons Licences, you may be free to re-use them without express permission. In general, permission will still be needed for use of material published under any licence incorporating the "Non-Commercial" terms, as IOP Publishing is considered a commercial entity for these purposes. Set out below is whether you are generally free to reuse figure(s) from articles made available under the following Creative Commons Licences without permission in your article*:
        • CC BY = OK to use figure without permission
        • CC BY-SA = OK to use figure without permission provided you make the figure available under the same licence or a compatible licence
        • CC BY-ND = figure cannot be used separately from the article without express permission of the copyright owner, as the article can only be used unchanged and in its entirety
        • CC BY-NC = figure cannot be used without express permission of the copyright owner, as this licence only allows Non-Commercial reuse
        • CC BY-NC-SA = figure cannot be used without express permission of the copyright owner, as this licence only allows Non-Commercial reuse
        • CC BY-NC-ND = figure cannot be used without express permission of the copyright owner, as this licence only allows Non-Commercial reuse & the figure cannot be used separately from the article
      *Please check the terms of the specific licence for full licence terms and attribution requirements.
 
    • Do I need to obtain permission to use a figure which was published on a gold open access basis, under one of the Creative Commons Licences? If the figure(s) you wish to use were published on a gold open access basis, for example under one of the Creative Commons Licences, you may be free to re-use them without express permission. In general, permission will still be needed for use of figure(s) published under any licence incorporating the "Non-Commercial" terms (see below), as IOP Publishing is considered a commercial entity for these purposes. Set out below is whether you are generally free to reuse figure(s) made available under the following Creative Commons Licences without permission in your article*:
        • CC BY = OK to use figure without permission
        • CC BY-SA = OK to use figure without permission provided you make the figure available under the same licence or a compatible licence
        • CC BY-ND = figure can only be used without express permission of the copyright owner, provided it is not part of an article which is also available under the CC BY-ND licence (if it is, see FAQ above)
        • CC BY-NC = figure cannot be used without express permission of the copyright owner, as this licence only allows Non-Commercial reuse
        • CC BY-NC-SA = figure cannot be used without express permission of the copyright owner as this licence only allows Non-Commercial reuse
        • CC BY-NC-ND = figure cannot be used without express permission of the copyright owner as this licence only allows Non-Commercial reuse
      *Please check the terms of the specific licence for full licence terms and attribution requirements.
 
  • How should I cite material which I am re-using under a Creative Commons Licence? Best practice when citing material published under a Creative Commons Licence is to cite the author(s), the title of the work, the type of licence and the copyright owner, whilst providing a link back to the source work and to the licence. However, in the context of academic publishing, this can be impractical. In the absence of specific citation instructions in the source material, IOP Publishing suggests the following format: For electronic-only use: Figure description E.g. Smith et al J. Phys. D: Appl. Phys (2013). CC BY. (Where "Smith et al" hyperlinks via DOI to the original article, and "CC BY" links to the full licence (e.g. http://creativecommons.org/licenses/by/3.0/).) For print use, the full citation can be included in a footnote.The most important consideration is that the licence type, licence terms, attribution and details of the source material are clearly communicated to the reader. The specific attribution requirements vary by licence, therefore you will need to check the particular Creative Commons Licence for full instructions.
Use of text
  • Do I need to obtain permission to use text taken from a prior publication in my article? You may quote brief chunks of text without permission. There is no set amount or word limit which may be used. It is assessed on a qualitative not a quantitative basis. If in doubt, permission will be required.The STM Permissions Guidelines 2014 allow with respect to a particular journal article or book being prepared for publication by an STM signatory publisher:
    • use of single text extracts of less than 400 words from a journal article or book chapter of another STM signatory publisher, but
    • not more than a total of 800 words from a whole book or journal issue/edition of another STM signatory publisher.

RE-USE OF IOP CONTENT

Content Published under the Subscription Model
    • What does "published under the subscription model" mean? The article will be fully protected by copyright and is generally only available to subscribers of the journal. There is generally no fee for publication on this basis, although just a couple of our journals charge article page charges.
 
    • How do I get permission to re-use figure(s) from articles published under the subscription model in IOP Publishing journals or its partner journals? Please refer to the Copyright & permissions page.
 
    • I am the author of an article published by IOP Publishing under the subscription model. Can I re-use figures/text from my own work? All IOP Publishing authors may include original figure(s) and text from their articles which are within the quota outlined in the STM Permissions Guidelines 2014 (the "Guidelines") in new works created or co-created by them, provided they notify IOP Publishing of their intended use. (See FAQ: How many figure(s) am I allowed to use under the STM Permissions Guidelines?)Where there are co-authors, the other authors should be informed.Use which is not covered by the Guidelines, or which exceeds the Guideline quotas, will require IOP Publishing's permission.
 
    • As a third party (not an author), can I use articles published by IOP Publishing for lecture and classroom purposes if the article was published under the subscription model? If your institution is a subscriber, use of this kind may be included in your licence - please check with your librarian. Non-subscribers may be permitted to do this under the terms of a licence from a local Reproduction Rights Organisation (RRO). In the UK, this will be the CLA (http://www.cla.co.uk/) and in the US, the CCC (http://www.copyright.com/).Pay-per-use permission for photocopying and electronic use is available via the CCC: http://www.copyright.com.
 
    • As a third party (not an author), can I request permission to re-publish figures/text from an article published by IOP Publishing if the article was published under the subscription model? Yes. Please refer to the Copyright and Permissions page. IOP Publishing handles permissions requests for its own journals and for most of the partner journals it publishes (see Copyright and Permissions page for which partners handle permissions requests themselves).
 
  • As a third party (not an author), can I request permission to re-publish an article published by IOP Publishing if the article was published under the subscription model? Please let us know the full details of your intentions, such as what material you wish to use, where the material will appear, in what format and if it will be produced by another publisher, including the name of that publisher. Please send as much background information for the request as you can to permissions@iop.org and we will consider and respond to your enquiry. We aim to respond to requests within 3 working days.
  Content Published under the Gold Open Access Model
    • What does "published under the Gold Open Access Model" mean? The article will be made available under a Creative Commons Licence, which means the article is free to view and grants certain rights to third parties. All gold open access articles published by IOP Publishing from circa 2013 are, unless stated otherwise, published under the Creative Commons Attribution 3.0 (CC BY 3.0) licence which means the article will be freely available for anyone to view and full re-use by third parties is permitted. Most gold open access articles published by IOP Publishing prior to 2013 are, unless stated otherwise, published under a Creative Commons Attribution-Non-Commercial-ShareAlike 3.0 (CC BY-NC-SA 3.0) licence which means that the article will be freely available for anyone to view and re-use for non-commercial purposes is permitted, provided they distribute the content under the same licence. An article publication charge (APC) applies for publication on this basis.
 
    • Do I need to get permission to re-use original figure(s)/text from an article published under a CC BY licence? No. Anyone may reuse any original content, such as figures or text, from gold open access CC BY articles in any way they wish, so long as they include attribution to the author(s), the journal citation and notice of the CC BY licence. For full licence terms and attribution requirements, please refer to the CC BY licence on the Creative Commons website. Please note that you will need to obtain the permission of the copyright owner(s) to reuse any third party material included within the article as this may not be subject to the CC BY licence.
 
    • Do I need to get permission to re-use original figure(s)/text from an article published under a CC BY-NC-SA licence? Yes. Anyone may reuse any original content, such as figures or text, from gold open access CC BY-NC-SA articles, so long as it is for non-commercial purposes, they include attribution to the authors, the journal citation and notice of the CC BY-NC-SA licence and they distribute the content under the same licence. Publishing in a journal article is deemed to be commercial use and therefore you will need to obtain permission to use any CC BY-NC-SA content in an article you submit to us. For full licence terms and attribution requirements, please refer to the CC BY-NC-SA licence on the Creative Commons website. You will need to obtain the permission of the copyright owner(s) to reuse any original content for commercial purposes or to use any third party material included within the article.
 
  • Where do I find more information on Open Access? For more information on Open Access, please refer to our main Open Access page.

COMPLETING IOP PUBLISHING'S ASSIGNMENT OF COPYRIGHT AND PUBLICATION AGREEMENT ("COPYRIGHT FORM")

    • Which section of the Copyright Form is applicable to me (hybrid journals)? Hybrid journals offer the option of publishing an article either under the subscription model or under the gold open access model. For information on which journals are hybrid, please see the section on our open access page "Which subscription journals offer an open access publication option?"Part 1 - If you wish the article to be published under the subscription model, the Subscription Copyright Assignment terms outlined in Part 1 of the form will apply. The article will be fully protected by copyright and generally available only to subscribers of the journal. There is generally no fee for publication on this basis.Part 2 - If you wish the article to be published under the gold open access model, the Open Access Copyright Assignment terms outlined in Part 2 of the form will apply. The article will be made available under a Creative Commons Attribution (CC BY) licence, which means the article will be freely available for anyone to view and full re-use by third parties is permitted. An article publication charge (APC) applies for publication on this basis. More information on APCs can generally be found on the Open Access Information page, accessed via the journal links on the specific journal home pages of our website.To indicate on which basis you want the article to be published, select the appropriate tick box at the end of the form (Part 1 or Part 2). However, if all authors are US Government employees, see FAQ: "All authors of the article are US Government employees and the article was carried out as part of our duties. Can I use the Copyright Form?" By submitting the Copyright Form, you are deemed to have accepted all of its terms.
 
    • Which section of the Copyright Form is applicable to me (pure subscription journals or pure gold open access journals)? If you have submitted the article to a pure gold open access journal (i.e. a journal which only offers publication under the gold open access model), or a subscription journal which does not offer a gold open access option, there will be no need to make a selection. However, you will still need to sign and date the Copyright Form.Please ensure that you familiarise yourself with the terms of the Copyright Form before submitting it. By submitting the Copyright Form, you are deemed to have accepted all of its terms.
 
    • What if I am not the sole author? Only one author needs to submit the Copyright Form, as authorised agent and on behalf of all the authors of their article. The submitting author will be deemed to have obtained the consent of all their co-authors to the terms of the Copyright Form and to submitting their article to the journal before completing the Copyright Form.
 
    • My work falls under Crown Copyright. Should I still sign the Copyright Form? Paragraph 1.2 of the Copyright Form is designed to accommodate the needs of Crown employees. Under this paragraph IOP Publishing takes a licence to publish the content which is subject to Crown Copyright. You should therefore be able to submit the Copyright Form in the usual way. If there are any particular requirements not covered by the Copyright Form, please contact copyright@iop.org.
 
    • All authors of the article are US Government employees and the article was carried out as part of our duties. Can I use the Copyright Form? Please select the "US Government" option to confirm that all authors are employees of the US Government and that the article was prepared as part of your duties and therefore the article is not eligible for copyright. Please note this does not apply to US Government contractors (whose articles will be protected by copyright) who should tick the appropriate box to indicate on which basis they want their article to be published.
 
    • Some but not all of the authors are US Government employees. Can I use the Copyright Form? If some of the authors are not US Government employees, then there is still copyright in their contribution to the article, which needs to be transferred. The Copyright Form needs to be completed and submitted by one of the non-governmental employees. They should NOT tick the “US Government” option as this is not applicable to articles where some of the authors are not US Government employees. Instead they should tick the basis on which they want their article to be published.
 
    • What if I do not own the copyright of the article I have written? If your research lab, organisation, employer (or someone else who is not an author of the article) owns the copyright to the article, they will need to agree to the terms of the Copyright Form by inserting their full legal name in the "Name of copyright owner(s) if not the Named Author(s) ("the Institution")" box at the top of the Copyright Form. One of the named authors should still sign and date the Copyright Form at the bottom as authorised signatory for their co-authors.
 
    • Do all articles require a Copyright Form? Authors must complete and submit the journal's Copyright Form prior to acceptance. This transfers copyright in their article to IOP Publishing or its partner(s). This ensures both that IOP Publishing has the right to publish the article and that the author has confirmed various things including that it is their original work and that it is based on valid research.In some cases, it is not possible for the author or their employer to transfer ownership of copyright. If you think that you require an exclusive licence rather than an assignment of copyright, please contact copyright@iop.org and explain why you require this. The Copyright team will assess your request, and if agreed, will provide an exclusive licence for you to sign.
 
    • What happens to the copyright in my article if it is rejected? The transfer of copyright in the Copyright Form has no effect until an article has been accepted for publication. On acceptance, the copyright in the article transfers to IOP Publishing or its partner(s). If an article is rejected by IOP Publishing then the copyright remains with the original copyright holder (i.e. the author or their institution) and the Copyright Form has no effect.
 
    • Do you take an assignment of copyright for all content accompanying my article? No, we only take an assignment (transfer of ownership) of copyright for the article itself. This does not include any supplementary material or any video abstract you produce for the article, in which we generally take a non-exclusive licence. We do not take ownership of the underlying data or science.
 
    • Do the answers to these questions apply to all IOP Publishing journals? These FAQs apply to the majority of the journals IOP Publishing publishes. Some partner journals may vary.
 
  • Queries If you have any queries on completing the Copyright Form, please contact the relevant journal mailbox or contact copyright@iop.org.

AUTHOR RIGHTS

For most journals, see our Author Rights page and refer to the FAQs below on depositing rights in repositories and on websites. For Author Rights for the AAS journals, see the pages below or contact permissions@iop.org: For Publications of the Astronomical Society of the Pacific, see the PASP Author Rights page.

ARTICLE VERSIONS

The following defines the different versions of an article as adopted by IOP Publishing: Author’s Original: the author's original version of the article before peer review or editing (this is also known as a 'Preprint'). Accepted Manuscript: the author's original version of the article including any changes made following the peer review process but excluding any editing, typesetting or other changes made by IOP Publishing and/or its licensors. Final Published Version: the version of the article published by IOP Publishing in the relevant journal. Version of Record: the final definitive, authorised version of the article, including editing, typesetting, any post-publication corrections or enhancements and any other changes made by IOP Publishing and/or its licensors.

DEPOSIT ON REPOSITORIES/SSNs – SUBSCRIPTION ARTICLES

IOP Publishing, like other publishers, grants authors varying depositing rights in non-commercial repositories/SSNs for the Author's Original and Accepted Manuscript of their articles published under the subscription model. Some of these rights only apply after the end of the applicable Embargo Period (as defined below). Embargo Period: A period of 12 months (save where stated to the contrary) from the date of first online publication on IOPscience of the Final Published Version by the Journal, as that date is specified on the article. A Creative Commons Licence, or any other form of open access licence, may not be attached to articles published under the subscription model. For example, authors may not post the Accepted Manuscript in repositories or Scientific Social Networks, which automatically apply an open access licence to the article which grants reuse rights under the terms of the repository or Scientific Social Network. The below queries and answers relate only to articles published under the subscription model, i.e those which are not published under the gold open access model. See section further below for gold open access rights. Final Published Version and the Version of Record – Subscription Articles Authors cannot make the Final Published Version of an article publicly available, or deposit it anywhere else or share it with anyone who is not a subscriber to the particular journal, except as set out in the signed copyright form. This includes authors not being permitted to deposit the Final Published Version of an article on their institutional repository, or on any other repository or Scientific Social Network. Third parties/subscribers cannot make the Final Published Version of a subscription article publicly available, or deposit it anywhere, or share it with anyone who is not a subscriber to the particular journal. The Final Published Version and the Version of Record of articles published under the subscription model must only appear on IOP Publishing’s website, IOPscience, or with the express permission of IOP Publishing. IOP Publishing reserves the right to issue take down notices on anyone who posts the Final Published Version of a subscription article to another website, a repository or a Scientific Social Network, without the prior written permission of IOP Publishing, or to take other action as it considers to be appropriate. Author’s Original and the Accepted Manuscript – Subscription Articles Authors are granted certain rights to deposit the Author’s Original and Accepted Manuscript of subscription articles elsewhere. Please see below for more information. Before acceptance
  • I am about to submit, or have already submitted, an article to an IOP Publishing journal. May I also submit the Author's Original to arXiv.org or bioRxiv.org? You may post the Author's Original on arXiv.org or bioRxiv.org at any time. Before acceptance of the article you may not attribute it to any IOP Publishing journal. After publication you should add citation information and a link, via DOI, to the Version of Record, along with the following wording: "This is an author-created, un-copyedited version of an article accepted for publication/published in [insert name of journal]. IOP Publishing Ltd is not responsible for any errors or omissions in this version of the manuscript or any version derived from it. The Version of Record is available online at [insert DOI]."If you plan to submit an article to IOP Publishing, it is important that you select the licence statement offered by arXiv/bioRxiv when uploading the article – a "non-exclusive licence to distribute" and not an open access or Creative Commons Licence. If you have selected an alternative licence, please notify copyright@iop.org as soon as possible following submission to IOP Publishing.Once you have posted the Author's Original on arXiv.org, you can submit it to IOP Publishing using the arXiv article ID number instead of uploading the files.
After acceptance or publication
    • My article has been accepted to be published in an IOP Publishing journal on a subscription basis. May I submit the Author’s Original to a non-commercial repository or non-commercial Scientific Social Network (SSN)?

IOP Publishing Ltd is not responsible for any errors or omissions in this version of the manuscript or any version derived from it. The Version of Record is available online at [insert DOI]."
 
    • May I post the Accepted Manuscript on a non-commercial institutional repository, non-commercial subject repository or non-commercial Scientific Social Network (SSN)? Following expiry of the applicable Embargo Period, you may post the Accepted Manuscript on a non-commercial institutional repository or non-commercial subject repository or to a non-commercial SSN, provided it is not under any form of open access or Creative Commons Licence and only where any copyright notice is not deleted or modified. Citation information, a link to the Version of Record and the following statement of provenance should be included: "This is an author-created, un-copyedited version of an article published in [insert name of journal]. IOP Publishing Ltd is not responsible for any errors or omissions in this version of the manuscript or any version derived from it. The Version of Record is available online at [insert DOI]."This is known as 'Green Open Access'.A Scientific Social Network is an "online scientific community platform for scientific communication and interactivity which generally includes, but is not limited to, users having the ability to chat and make comments on forums, post their profiles, deposit documents in repository facilities, share information and research, find collaborators, work on shared documents together and manage collaborative projects within groups".You may not post the Final Published Version online, unless it has been published under the gold open access model after payment of an article publication charge.
 
    • Does this satisfy the requirements of most research funders for 'Green Open Access'?
