There is an active scientific publishing community in Croatia. The first Croatian Open Access initiative was launched in 1997, when Hrvatska znanstvena bibliografija (Croatian Scientific Bibliography or CROSBI) went online. CROSI allows researchers to search for scientific articles and books that were published in Croatia. 

As of March 2021, there are 134 OA journals indexed in DOAJ which have been published in Croatia. There is also a central portal of Croatian scientific journals (Hrcak) which offers Open Access to over 250 journals. As of May 2013 the Hrčak portal of scientific journals hosted 333 journal titles with 91,737 full-text articles, including dozens of journals in the Humanities and Social Science fields. Both the CROSBI and Hrčak demonstrate the effectiveness of Croatian open access policy initiatives. Whereas the official statement on open access in Croatia became public in October 2012, the projects that supported these initiatives came to fruition at a much earlier date. Although the success of these two open access projects may not point to a generalized conclusion about the development of open access in the Croatian context, their success clearly indicates a promising future for open access policy initiatives in Croatia

There are nine public universities (Zagreb, Split, Rijeka, Osijek, Zadar, Dubrovnik, Pula and Slavonski Brod) and 30 public and private polytechnic institutes, with more than 180.000 students enrolled. Research in Croatia is also conducted by 25 public institutes and six technology centres. There are approximately 11.500 active researchers in Croatia. The largest university in Croatia is the University of Zagreb with more than 70.000 enrolled students, and the largest research institute is Ruđer Bošković Institute with more than 550 researchers.

139 OA institutional repositories are registered in OpenDOAR. 02 institutional OA policies are currently registered in ROARMAP

Enabling Environment

Croatia is part of the European Research Area (ERA) and supports open science through different Open Access initiatives. Numerous bottom-up initiatives at the national level make Croatia a vibrant OA environment.

University of Zagreb Medical School Repository is a fully functioning OA institutional repository. Academic librarians have high awareness of OA. The public nature of the Croatian publishing industry lends itself to OA and self-archiving – publishers of Croatian scientific journals are non-for-profit organizations (mostly universities, scientific associations, scientific institutes) and they allow self-archiving. 

Potential Barriers

Lack of national mandates; non-Croatian publishers that publish research results of Croatian scientists do not always support OA – some of the articles written by Croatian scientists and published abroad cannot be self-archived (i.e. made accessible through OA repositories).

National and Institutional Level Policies/Mandates

None, although in the Ministry of Science, Education and Sports’ document “Science and technology policy of the Republic of Croatia 2007-2010” it is specified that the results of research (all research is publicly funded) should be accessible to the general public through open publications or databases.

The Croatian Research and Innovation Infrastructures Roadmap 2014-2020 addresses the promotion of OA to scientific papers and research data, especially those funded by public sources. MSE’s Strategy of Education, Science, and Technology (in Croatian) recognizes that setting up an OA system for research data, publications, and teaching resources is a key to improving the research environment.

Research data sharing in Croatia is in its initial phase, and researchers are not encouraged and/or rewarded for sharing their research data, except when mandated by funders (e.g. EC through H2020 projects).

The national contact point for the open access to the scientific information is Jadranka Stojanovski, appointed by the Croatian Ministry of science and education.

Research institutions in Croatia are autonomous, but they strongly rely on national policies and regulations. There are only a few institutional OA mandates, such as those of the RBI, SRCE, Faculty of Mechanical Engineering and Naval Architecture of the University of Zagreb, and the Physics Department of the Faculty of Science at the University of Zagreb, mostly addressing OA to publications. Only SRCE’s OA policy includes research and other data management.

Funding Mandate

Ministry of Science, Education and Sports’ document “Science and technology policy of the Republic of Croatia 2007-2010” it is specified that the results of research (all research is publicly funded) should be accessible to the general public through open publications or databases.

New OA mandates

On 17 April 2015, the Rudjer Boskovic Institute (RBI) adapted a new OA Policy which mandates researchers to submit a digital copy of all articles to the institutional OA repository FULIR (which is OpenAIRE compliant)  upon acceptance for publication. 

Some institutions provide support for OA and ORDM activities for their researchers. The level of support varies and usually consists of infrastructure, training for using the infrastructure, and creation of DMPs.

Key Organizations

Three public bodies play a major role in the consolidation of the research at the national level in terms of:

• strategy with the Ministry of Science and Education (MSE)

• funding with the Croatian Science Foundation (HRZZ)

• development and assessment with the National Council for Science, Higher Education and Technological Development (NCSHETD) and Agency for Science and Higher Education

Compliant with Open Access Initiative protocols. Communication address: University of Zagreb, Medical School, 10 000 Zagreb, Šalata 3; e-mail: smk(at)

Croatian Information and Documentation Society (HID)

Overview: Established to develop information and documentation sciences in Croatia, to promote professional principles and encourage free flow or materials including OA initiatives.

OA mandate: Article 7 of HID Statute includes “encouraging development of free flow, access and openness of scientific, professional and public information channels, which derives from the users right on information is making them equally accessible to everyone”.

Communication address: HID c/o National and University Library, Hrvatske bratske zajednice 4, 10 000 Zagreb, Croatia; e-mail: Marina Mayer, secretary, e-mail: mmayer(at)

Croatian Information and Documentation Society’s (HID) OA working group initiated in 2004. The result was the launch of the Hrcak portal for Croatian scientific journals (supported by the Ministry of Science,  Education and Sports, developed and maintained by University Computing Centre SRCE).
