Introduction

The Ministry of Education, Youth and Science has responsibility for education and research. The Bulgarian Academy of Sciences coordinates research programmes with National Science Fund as the main funder. The Parliament (Narodno sabranie) plays the key role in decision making about matters that concern the network of higher education institutions in the country.

As of March 2021, DOAJ indexes 74 OA journals. OpenDOAR registers 10 OA digital repositories.

There is currently one OA policy registered in ROARMAP.

Enabling Environment

The major research funder in Bulgaria is the National Science Fund.  Promotion of Open Access is more of an individual effort, than the result of institutional support or policy.

The Bulgarian Academy of Sciences (BAS), the coordinator of research in Bulgaria, intends to establish a network of scientific Open Access centres. Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences (IMI-BAS) will be the coordinator of the Bulgarian network and will provide support for academic institutions and researchers. IMI-BAS launch a national project to develop the research infrastructure and digital repositories for researchers, educators, public bodies and companies who need contemporary scientific and education information and resources. This foster integration between academia, the public sector and industry strengthen the institutional links between all major research and education organizations.

The Bulgarian research community is informed about the benefits of Open Science, Open Data, and Open Access. Some of the main activities in Bulgaria concerning open access include:

Maintaining the National Open Access Desks which connect researchers, research institutions, and policymakers at a national level on the one end, and the OpenAIRE project services on the other. The focus of the National Open Access Desks activities supports compliance with the EC Open Access policies;

• Maintaining the Bulgarian repositories for Open Access;

• Organizing conferences, workshops and seminars;

• Developing a policy vision for the development of the Open Access and Open Data, presented to the EC.

Key Organizations

• New Bulgarian University (NBU). The first private and one of a kind educational institution in Bulgaria acquiring national level of excellence in higher education by adopting innovative practices and developing critical analysis. The institutional repository, based on ePrints platform is the first operating repository in Bulgaria, designed and developed to enhance access to crucial up-to-date Bulgarian research output and preserves e-production of NBU academic staff and post-graduate students. Communication address: New Bulgarian University Library, 21 Montevideo Street, Sofia 1618, Bulgaria; Repository Editor, Head of Library and Information Services Department (Mrs. Radostina Todorova); e-mail: rtodorova(at)nbu.bg; Technical Support System Librarian (Tanya Stoyanova) e-mail: tstoyanova(at)nbu.bg

• Institute of Mathematics and Informatics at Bulgarian Academy of Sciences (IMI-BAS). Main mathematical centre of excellence with high priority on research.  Bulgarian Digital Mathematics Library (BulDML) at IMI-BAS is participating in a European network for mathematical repositories - the project EuDML (The Europian Digital Mathematics Library) which brings together the dispersed European heritage of digital mathematical literature in virtual collections. BulDML is based on Dspace digital depository. Currently (September 2012) there are more than 1500 publications from 6 journals and 2 proceedings. Communication address: Institute of Mathematics and Informatics, Acad. Georgi Bonchev Str., Block 8, 1113 Sofia, Bulgaria; Peter L. Stanchev, Ph.D., D.Sc.
