 "Publications" are items that are classed as "article", "review" or "proceedings paper" in the Web of Science (WoS) database; other items like editorials, corrections, notes, retractions and discussions are excluded.WoS is accessible to all registered users, who can independently verify the number of citable items for a given journal.In contrast, the number of citations is extracted not from the WoS database, but from a dedicated JCR database, which is not accessible to general readers.
