The German library system is organised in six library unions (Bibliotheksverbünde), whose virtual union catalogues contain all references from their member libraries. Recently, all six union catalogues are contributing to the Combined Consortial Library Index (Gemeinsamer Verbündeindex, GVI), aiming to facilitate inter-library loan.

Out of these millions of catalogue references, we select those relevant to comparatists for The selection follows the "broad profile" for content and information available on

In addition to the catalogue data, selecting from the GVI allows to integrate availability information from almost all scholarly libraries in Germany. Thus, users can determine if a title is available for loan at their local library, or if it needs to be ordered by inter-library loan.

The Staatsbibliothek zu Berlin – Preußischer Kulturbesitz (Berlin State Library – Prussian Cultural Heritage) has an extensive collection in the field of general and comparative linguistics and literature.

"General linguistics and literary studies as well as comparative linguistics, comparative literature and Indo-Germanic studies interact strongly with the individual philologies. This constellation, in conjunction with the traditional cultivation of most of the philologies in the Staatsbibliothek zu Berlin (SBB-PK), results in a high demand for literature, which must be met by acquiring a very broad selection of literature. Even more so than in Germany, comparative literature and general linguistics in the Anglo-American world are disciplines with extensive publication activity. Added to this is the interdisciplinary character of the subjects, which are relevant not only for research in the individual philologies, but also and especially in the field of media, film and theatre studies. General and Comparative Linguistics and Literature is therefore a focal point of the SBB-PK collection. There is no focus on particular topics, nor are there any limitations in terms of content."
