E-rara.ch is a project that aims to make all Swiss books from the 16th century available online. In a later stage of the project incunables, 17th century works and other materials will be added.

E-rara.ch is undertaken in the framework of the joint project E-lib.ch: Elektronische Bibliothek Schweiz by several partners: Bibliothèque de Genève, ETH-Bibliothek Zürich, Universitätsbibliothek Basel, Universitätsbibliothek Bern and the Zentralbibliothek Zürich. Other participating libraries are BPU Neuchâtel, the Bibliothèque des Pasteurs, the BCU Lausanne and the BCU Fribourg.

At the moment the following collections are available:

• Swiss prints from the 16th century
• Astronomy
• Architecture and urban construction

The collections can be browsed by title, author, place, publisher and year.
