European theological libraries are cooperating with national, professional, ecumenical and denominational networks to make their collections visible. The majority of European countries have a national catalog and within them, one can search for theological collections and resources mostly coming from theology faculty libraries. But there are also joint catalogs and search engines of religious literature in Europe organized by theological library associations and specific libraries.
Below is a list of some of these projects across Europe, all of which are available in the public domain.
