V3S detects suspected duplicate records according to WoS, Scopus and DOI code compliance – display on the result check tab, on the home page and in the search results. Also added new search filter options and listing columns: suggestions for links to WoS and Scopus (previously displayed only on the home page), www links and a set of research data. New types of results (popularization lecture and article, media appearances) and recognition (award for popularization). Added the ability to display citations for approval on records that I can edit on the home page.
