Index Copernicus (IC) is an online database of user-contributed information, including scientist profiles, as well as of scientific institutions, publications and projects established in 1999 in Poland, and operated by Index Copernicus International. The database, named after Nicolaus Copernicus (who triggered the Copernican Revolution), has several assessment tools to track the impact of scientific works and publications, individual scientists, or research institutions. In addition to the productivity aspects, IC also offers the traditional abstracting and indexing of scientific publications.
The Index Copernicus aimed to offer an alternative to the English language dominance of publication indexing systems. The enterprise was co-financed by the European Regional Development Fund under the name: "Electronic Publishing House of Scientific Journals system of Index Copernicus Ltd."
IC's journal ranking system was criticized in 2013 by Jeffrey Beall because of the high proportion of predatory journals included in it and its suspect evaluation methodology; he characterized the resulting "IC Value" as "a pretty worthless measure".
