The Open Ukrainian Citation Index (OUCI), a search engine and scientific citation database based on the metadata of Crossref publications, is integrated with the contents of the open database Unpaywall, which contains information on over 25,500,000 legal free scientific publications. The OUCI users can quickly find open publications simply by using the Open Access search filter.
The database Unpaywall receives data directly from more than 50,000 open journals and repositories worldwide, and uses open data from PubMed Central, DOAJ, Crossref and DataCite. The Unpaywall is supported by Impactstory, a non-profit organization that helps make science more open and research results accessible to reuse.
If you want to make sure that the content of your journal or repository is submitted to Unpaywall, or if you want to add your open repository or journal to your Unpaywall source list, use the link below.
Thousands of OUCI researchers around the world will now save more time and effort in finding the full text of research papers. Institutional repository managers will also benefit from the integration by improving the content of their open electronic repositories in the global information space.
