Various staff or divisions of the Library of Congress compiled or researched topics related to Bulgaria, beginning with the Cold War era when the Library took the lead to produce basic reference tools about Eastern Europe, and continuing to more recent times with articles on the historical development of the Bulgarian collection. This page gathers those materials together and either reproduces them in their entirety or links to freely available digital copies. Titles link to fuller bibliographic information in the Library of Congress Online Catalog. Items linked to pdf copies are immediately below, whereas articles reproduced in their entirety each are presented on their own page. Additional titles produced by the Law Library of Congress are included in the Guide to Law Online: Bulgaria under the section "Legal Guides - Law Library of Congress Resources."
