Digitization at the Library

Book Digitizations

We have a growing collection of digitized books, comprising more than 1.400 titles. We digitize mostly rare books, but also modern specimens. The total number of scans as of 2020 is nearly 350.000. A distinguishing feature is that all volumes can be integrated into digital platforms using the IIIF API. The digitized volumes are listed here:

Newly acquired rare books -- which for the most part are not yet digitized -- are listed here. This is a good starting point if you want to keep yourself informed of our ongoing rare book acquisitions in the fields of guide books (Italy, Switzerland, France, Germany) and 20th century colonialism.

Book Projects

In 1924 Julius von Schlosser published his »Die Kunstliteratur«, a collections of primary sources for the history of art. Of the ca. 1400 cited titles, most are owned by our library and have been digitized. The transcription of the »Die Kunstliteratur« with direct links to all digitized sources is here.

Ludwig Schudt's »Le Guide di Roma«, published in 1930, lists nearly all known guide books of Rome. The publication has been transcribed and all sources cited by him have been linked to digitized specimen - most of them from our own extensive collection.

Finally, there's a new project coming about the artistic treasures of the town of L'Aquila, developed in partnership with the university of l'Aquila. The transcription of Leosini's »Monumenti storici artistici della citta di Aquila« from 1848 will be accompanied by an exhaustive comment and its cited monuments located on a interactive map. The website is only a mock-up.

Pablo Echaurren

This archive comprehends more than 1.000 pieces of pamphlets, sketches, photographies and printed materiel from the collection of Pablo Echaurren. A special website is being prepared. An announcement will be made in September 2020.

Early Texts on Perspective

We have collected some early printed and manuscript texts about the theory of perspective, with relevant modern documentation. Originally this was intended as a place for collaborative editing (using the annotate.it toolkit). The toolkit is no more, but the documents are still open.

Place Names of Rome

The data here exposed come from the -- now defunct -- LVPA Project by Andreas Thielemann. Exemplary guide books of Rome were manually indexed and all better known place names registered. The result was a database covering the most famous place marks of Rome -- more than 1.100 toponyms -- with more than 15.000 direct links into our digitized volumes.

Geographic Metadata Mapped

The data here comes from our bibliographic data stored in the OPAC - or better, the catalogue of our consortium. Specific keywords have been extracted - municipalities in Italy and some selected places in Rome - and mapped onto a map of Italy.

Digital Cartography

We've georeferenced some of the (better) maps of Rome, Latium and the Abruzzi from the library material. The results are quite nice, even more when overlayed on top of modern maps. They are collected here:

Surface Scans

Digitizations of surfaces (paintings, leather bindings, et al.) proved to be very interesting. A deeper look at the surface allows for better understanding of the production technique, of restorations and environmental damage. Some examples are collected here:

3D Object Digitizations

3D scans of our rare book collection proved to be a good approach to present the materiality of our objects. A good example is the 1493 german edition of Hartmann Schedel's »Buch der Chroniken«. We've also done some digitizations of frescoes from rock sanctuaries in the Abruzzi region, too (»Santa Maria dell Ritornata« near Civita d'Antino). All digitizations have been executed using photogrammetry.


All of our digitized volumes are accessible using the Open Archives Initiative Protocol for Metadata Harvesting . The Getty is using this API to include our collection into its Research Portal . The use of our API is free.


All of our digitized volumes are accessible using the International Image Interoperability Framework . This allows harvesting of volumes and -- even more importantly -- single scans bypassing traditional HTML interfaces. The use of the IIIF API eliminates the cumbersome download process and facilitates distributed research.

Online Database and API

All titles held by the library have been uploaded to DBHub.io . They can be queried directly using SQL (as of now, select statements only) or using the DBHub API . Results can be exported as CSV or SQL. This allows mass querying and harvesting of titles in a more convenient way than by using the BVB Open Data , limited to 25 results per query.
