This document provides an introduction and overview of the "Books Discovered Once Again" project from the National Library of the Czech Republic. The project will catalog and digitize over 12,000 confiscated books in the library's reserve collection to research their origins and legal status. Key activities include accessing the documents, researching their historical context, assessing their legal status, and presenting results through a website, publications, and exhibitions. The project runs from January 2015 to April 2016 with a budget of over 13 million CZK shared between the National Library and collaborating Stiftelsen Arkivet organization.
