Established in 1947, the Union of Slovene Library Associations aims to develop library programmes, to promote professional education and to protect the professional interests of its members. It comprises several sections focusing on public libraries, special libraries, school libraries, academic libraries, mobile libraries, local history collections and students of library sciences. Committees have been set up for cataloguing, bibliography, terminology, subject classification, training and education, preservation and restoration and standards. The Union is a member of the International Federation of Library Associations and Institutions (IFLA) and the International Association of School Librarianship (IASL). It co-operates with the European Bureau of Library, Information and Documentation Associations (EBLIDA) in the Central and Eastern European Copyright User Platform (CECUP) and the Central and Eastern European Licensing Information Platform (CELIP) projects.

The Union of Slovene Library Associations has member Library Associations in Celje, Dolenjska, Gorenjska, Koroška, Ljubljana, Maribor, Pomurje and Primorska. It publishes the quarterly Knjižnica (Library) Magazine and bestows the annual Čop Award for achievements in librarianship.
