This chart shows the 2-year review impact factor of Organic Process Research and Development over time and its percentile among journals. Only review articles are counted in both the numerator (citations) and denominator (citable items).
The 2-year review impact for year X equals the citations received in year X to review articles published in years X-1 and X-2, divided by the number of review articles published in those two years. Unlike the standard 2-year impact, only items classified as review articles are counted in both the numerator and denominator.
