Unrestricted and immediate access to new medical information is globally important. Open access (OA), availability and searchability of new research results have a significant positive impact in medicine, from research and education, to everyday medical practice. In the last decades, numerous efforts have been made to promote OA as a reliable and efficient model for communication, dissemination and deposit of medical information: from Bethesda Statement to OA mandates of prominent institutions and organisations (such as US National Institutes of Health, Welcome Trust), from PubMed and PubMed Central to Biomed Central and PLoS journals, etc. Therefore, OA has been rooted in biomedicine deeper than in any other science and technology discipline. According to a study published in 2010 by Bjork et al., the percentage of OA articles in the field of medicine was 21.7% on average (1).
Support and practice of OA has been growing in Croatia (eg. Hrčak archive, national Declaration on Open Access) as well as at the University of Zagreb School of Medicine (UZSM).Croatian Medical Journal, the official journal of all university medical schools in Croatia uses gold open access model since 1997, and it has been included in PubMed Central since 2006. On the other hand, UZSM employs the green way through its institutional repository, established in 2007.
