Volume I, which was originally published in 1915, catalogues the incunabula in the collection. Volume II catalogues later printed books, and Volume III autographs, including books and autographs relating to the French Revolution. Volumes I & II were compiled by Frederick W. Ashley and Volume III by Henry Eldridge Bourne with the assistance of Gertrude Albion MacCormick.
Interestingly, the notes in Vol. II seem to have been written by someone intimately involved with the collection. Very good .
