The full conservation treatment performed on a large 19th-century Canadian photograph album at the National Archives of Canada is outlined in detail. The Jacobs Album, considered to be one of the most valuable in the collection, was completely taken apart. All 913 photographs were lined and remounted onto new pages, and new bindings were constructed. The original pages and binding jackets were treated and stored separately. Also outlined are the treatment options presented prior to treatment and the decision-making process that resulted in this treatment.
