There is a so-called collection share between the ELTE libraries, whereby the libraries of the various faculties and the collection of the University Library and Archives together provide direct access to the specialized literature of the sciences taught and researched at the university.
Under this agreement, the University Library and Archives collects academic works in the fields of social, human, and economic science, in Hungarian and in foreign languages (mainly English, German, French), which discuss their content in alignment with the depth of current scientific research. In accordance with The Doctoral Regulations, the University Library collects the dissertations defended in doctoral schools.
