The Library of Congress has limited electronic resources for Bulgaria in comparison to its print holdings. Nevertheless, the collection of electronic materials is growing every year. Digitized versions of photographs, maps, rare books and other public domain materials appear on the main Library of Congress website using the search box at the upper right to locate materials and limit by material type.
Although the Library does not subscribe to any full-text databases devoted solely to Bulgarian publications, some scholarly journals appear in the subscription database Central and East European Online Library. Another subscription database with full-text of Bulgarian titles is EMIS Intelligence, which has a selection of Bulgarian business reports and news, including from the Bulgarian News Agency (BTA). These databases and others are described in the section of this guide titled Onsite Only Electronic Resources. Although the contents of the various databases may be accessed only onsite, prior to a visit you can search the Library of Congress Electronic Resources Catalog from offsite to discover which databases and e-journals we offer. Also, for online news content, consult the section for online newspapers in the Library of Congress guide Bulgarian Newspapers in the Library of Congress.
In 2021 the Library of Congress began transitioning away from preservation microfilming and towards digitization of Bulgarian newspapers. All digitized newspapers and other rights restricted electronic content are available via Stacks, an onsite-only database. To discover what newspapers have been digitized before you visit, consult the guide Bulgarian Newspapers in the Library of Congress, which is updated annually to reflect new acquisitions and format changes of materials.
The Microform and Electronic Resources Center (MERC) holds a small collection of Bulgarian CD-ROMs, mostly of statistical titles that are no longer being published in paper available. Materials are findable via the online catalog. Lastly, the Library of Congress has been web archiving Bulgarian government and political websites beginning in 2014 and 2020 respectively. The web archiving content from Bulgaria is described in the section of this guide titled Web Archiving.
The final section of the guide under the rubric of Digital Resources is an annotated list of various openly available Bulgarian resources which we have found to be helpful for research about the country and its publications.
