Digital Resources
The Photothek's digital and electronic resources can be freely consulted online. They include the digitized negatives and positives in the Digital Photothek, a searchable index yielding the accession date of each individual photograph, a collection of 19th and early 20th-century sales catalogues published by various European photographic studios, the Photothek's online exhibitions, its digitized collection of prints and engravings and a platform (Virtual Photothek) with further digital projects. Plans are being made to digitize the inventory books and the card catalogues.
