The Catalogue seeks to put the entire corpus of the approximately 20,000 known surviving Talbot negatives and prints online.

On 31 January 2019, we moved from the 'developmental'phase to the'delivery' phase. However, new material is being added periodically. Please help contribute to this project.

From May 2015 to January 2019 a new blog was posted every Friday. Covering a wide range of basic and specialized topics, these were normally written by the Director but many were contributed by Guest Editors. The topics were often unpredictable. The blogs are archived and fully searchable. From now on, blogs will come out on a periodic unscheduled basis. You can subscribe to a reminder if you wish.

Internal resources include biographies, bibliographies and case studies. The Catalogue is also being linked to a wide range of external resources in the study of the early history of photography, including correspondence, conservation and historical studies.
