This year, more than half of the titles published by IOP have seen significant increases in citations from last year. 14 titles have had an increase of over 10% and 17 of IOP’s journals now have Impact Factors above 3.000. Over half the portfolio has an Impact Factor over 2.000.

Our full results will be published on IOPscience shortly.
