A survey of publications with chironomid content represented in bibliographic databases on the web

Abstract

Three online databases were searched between the 9th and 12th of December 2013. Each basic search operation covered a single calendar year only; sum totals calculated for longer periods were checked by searching with corresponding year ranges, where the entry fields and search functions allowed this. Many data for 2013 have yet to be entered in the databases; thus, this year can be considered only as far as general trends.
