ENRICH is a targeted project funded under the eContent+ programme. Its objective is to provide seamless access to distributed digital representations of old documentary heritage from various European cultural institutions in order to create a shared virtual research environment especially for study of manuscripts, but also incunabula, rare old printed books, and other historical documents. It builds on the Manuscriptorium Digital Library (http://www.manuscriptorium.eu) that has already managed to aggregate data from 46 collections from the Czech Republic and abroad. The project groups together almost 85% currently digitized manuscripts in the national libraries in Europe. These collections will be enhanced by substantial amount of data from university libraries and other types of institutions. The consortium will make available more than five million digitized pages.
