Paul Deschamps' archives were divided into two parts in the 1970s, and bequeathed by his daughter, Mrs Geny, to two public bodies. The archive service of the Monuments Historiques, now the Médiathèque de l'architecture et du patrimoine, was given some 2,200 negatives of photographs taken by Deschamps and Captain Lamblin, as well as animated films. The collection mainly covers the Near East and has several dozen pictures of the Krak including architectural photos, but also photos of the excavation site and Western visitors to the castle. A remarkable witness to the state of the Crusader fortresses in the Near East in the early 20th century, the collection was fully digitised in the summer of 2016 and placed online in the course of 2017.
The other collection, which includes the papers of Paul Deschamps, was donated to theInstitut national d’histoire de l’art in 1976 by Mrs Geny. It bears the number "Archives 001", and represents approximately 3.3 metres of documents, classified and catalogued in 2015-2016 by Clément Moussé. It contains Deschamps' personal notes on his successive missions (notebooks, correspondence, etc.) and the documents (proofs, notes, and prints) he used to write his three volumes on Crusader architecture.
