To support and stimulate with core reference collections and information services the independent research, intellectual creativity and dialogue on a national and regional scale.


The Library of the Centre for Advanced Study Sofia is developing collections of printed and electronic resources in the area of Humanities, Social Sciences, and Balkan Studies in the modern and contemporary era. It aims to serve as a Balkan information center about major scientific forums in these fields which take place in Bulgaria, the region of Southeast Europe and the Western Europe. The library is an open-stack, lending facility primarily designed for the use of CAS Fellows, but it is also open to the general public upon request. It provides library and reference services based on traditional and electronic information sources.

“The Balkan Bibliography” is a successful project of the CAS Library in co-operation with the National Library. It has created a bibliography of monographs, encyclopaedias, reference books and articles published in Bulgaria in the period 1985-2001. On the basis of the electronic databases a bibliographic index on ‘Bulgarian Publications in Balkan Studies 1985-2001’ has been published in April 2003.

CAS Library hosted a meeting of directors of Balkan national libraries and presidents of library associations from Albania, Greece, Macedonia, Romania, Serbia, Slovenia and Turkey in 2002, and a meeting of bibliographers from the national libraries of Bulgaria, Serbia and Macedonia on the 12th of June 2003.


The CAS Library collections and services are mainly specialized in the sphere of the Humanities and Social Sciences with focus on the Balkan Studies area. Collections consist of: books and monographs; periodicals; reference collections; online academic databases; offline database “The Balkan Bibliography 1985-2001″; special collections (monographs, articles, periodicals, bibliographical data, Internet resources) created for the purposes of each separate CAS project.


The CAS library serves and supports in a traditional and electronic way the CAS Fellows and external academic researchers with:

  • Books loans (only for CAS fellows);
  • Access to the collection of periodicals;
  • Access to online academic databases;
  • Written bibliographical references.

Questia is the first online library that provides 24/7 access to the world’s largest online collection of books and journal articles in the humanities and social sciences, plus magazine and newspaper articles. You can search each and every word of all of the books and journal articles in the collection. You can read every title cover to cover.
