The data above were extracted from the Thomson Reuters Essential Science Indicators database. This database, currently covering the period January 1999 to June 2009, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based on the journals in which they were published and the journal-to-category field-definition scheme used by Thomson Reuters. Hot papers are limited to those articles published in the last two years. A paper is selected if it meets a citation-frequency threshold determined for its field and bimonthly group. Citation-frequency distributions are compiled for each field and cohort. Thresholds are set by finding the closest citation count that would select the top fraction of papers in each field and period. The fraction is set to retrieve about 0.1% of papers. Here we focus on hot papers published this year; of course, papers published early in the year have had more time to collect citations than those more recently published.
