How to find if a paper is in top 10% most cited articles in a journal?
Go to Web of Knowledge and search by publication name. Then sort by citation count and find the 10% cutoff (e.g. if there have been 10,000 papers published in that journal, then the article with the 1000th highest citation count is the 10% cutoff). Then find the paper you're interested in, and see if it's above or below that 10% cutoff.
