What is e-rara.ch?
e-rara.ch is the portal for digitised printed works from Swiss libraries. These works range from books and maps to illustrated materials – from the earliest days of book printing to the 20th century.
e-rara.ch pursues the following objectives:
- Coordinated digitisation of printed works from the 15th to the 20th century from Swiss libraries in accordance with uniform quality standards
- Central import into the portal of digital documents and bibliographical metadata
- Persistent DOI referencing of electronic documents
- Presentation of full texts, maps and illustrated materials on a common portal
Swiss printed works are digitised to some extent in collaboration with the digitisation activities of German libraries. e-rara.ch makes its metadata available to international portals like Gallica and the SAO/NASA Astrophysics Data System (ADS) run by Harvard University.
The portal was developed as part of the e-lib.ch: Elektronische Bibliothek Schweiz project and went online in 2010. It is run by Bibliothèque de Genève, ETH Library, Universitätsbibliothek Basel, Universitätsbibliothek Bern and Zentralbibliothek Zürich. Many other libraries are contributing to the expansion of the portal with their stocks.
