About FBC?

What is FBC?

Digital Libraries Federation (Federacja Bibliotek Cyfrowych, FBC) is a search engine that brings together digital libraries, museums, archives and repositories.


We work with cultural and scientific institutions that form a network of distributed digital libraries. In digital libraries, institutions upload scans with descriptions of their resources-books, journals, images. Descriptions in the form of records are sent to our search engine. Thanks to the descriptions (so-called metadata), the user is able to search museum, library and many other collections in one place.


A scattered network of digital libraries centralized in FBC.


The mission of FBC is to make available and promote Polish cultural and scientific achievements. The use of the search engine is completely free, as well as the transfer of records to it. We believe that the preservation and sharing of cultural heritage resources supports the development of institutions and users.


We encourage institutions, libraries, museums, repositories to use Creative Commons licenses, which allow wider use of digitized resources. http://fbc.pionier.net.pl/pro/wp-content/uploads/2019/05/FBC_Plakat_Prawa_Autorskie_PL-1.pdf


We support the quality of metadata through the creation of PLMET schema. Metadata is the most important source of information about a digital object, its quality is crucial for processing and presentation in search engines.


The search engine was created in 2007. Developed at the Poznan Supercomputing and Networking Center in the Department of Digital Libraries and Knowledge Platforms. Since its inception, it has supported resources provided in the DInGO package, as well as in other repository systems with the OAI-PMH protocol.
