The Open Ukrainian Citation Index (OUCI; http://ouci.dntb.gov.ua/en) was launched this month by Ukraine’s ministry of education and science, in conjunction with the country’s State Scientific and Technical Library. This database could be particularly useful for tracking relationships between findings that concern regional topics and target domestic audiences, which are typically published in Ukrainian journals (see also A. J. Nederhof Scientometrics 66, 81–100; 2006).

Scholarly communication systems often fall short in revealing knowledge networks if their bibliographic and citation data are not in machine-readable form. The OUCI database, which comprises citations from all publishers that use Crossref’s Cited-by service, corrects this problem. It upholds the aims of the Initiative for Open Citations, a collaboration of scholarly publishers, researchers and other stakeholders. It is accessible to researchers and the public, and it accounts for citations between publications (DOI to DOI) without the need to open the source articles. The database contains information from databases such as Scopus and the Web of Science, and can also be searched in English.
