Wallace's field notebooks, diaries, artwork etc have all been catalogued by the Wallace Correspondence Project (WCP), but are not in EPSILON because EPSILON is restricted to letters. However, most of them are available online via other websites - see below. Note that all of these documents have been assigned unique identifiers by the WCP, and these should be given when they are cited.
