Principles of description :
The cataloguing principles used have been specially established to describe the history and stigma of positive photographic prints, not the images as referenced by their negative numbers.
When an old photographic print leaves a library or an attic, or a simple documentary record enters a collection or a museum; the way we look at it changes at the same time, this is what we seek todescribe. The description accompanying a photograph signifies and transforms its meaning.
Each of our descriptions begins with an author's name, thus emphasizing the artistic nature of photography.
