The fonds is separated into three series: Manuscripts, Working Notes and Osler's Correspondence. It also contains photographs, annual reports, publications, clippings, one watercolor painting, one postcard. Osler's correspondence is further arranged in three subseries based chronologically.

Fonds consists chiefly of ephemera and correspondence relating to the work of wood engravers of Thomas and John Bewick of Newcastle, England, in the late eighteenth and nineteenth centuries. The ephemera found in series 1 includes various examples of fine printing, including proofs and printed keepsakes featuring Bewick engravings from printers such as Havilah Press and Anchor and Acorn Press. Series 2 contains correspondence, chiefly between Geraldine Cole and booksellers, as well as general correspondence with friends and acquaintances. Series 3 consists primarily of bookseller descriptions and clippings and excerpts from catalogues describing Bewick works (generally with the catalogue cover appended to a loose page on which a Bewick item appears). Some are with accompanying correspondence. Also included in this series are documents listing all of the items found in the Cole-Bewick Collection at McGill Library. Series 4 consists of other ephemera related to Bewick and his life, including short biographical pieces, postcards and products featuring Bewick engravings and watercolours, and articles and clippings. The last file in this series contains 4 original letters from Thomas Bewick to various correspondents, dating between 1819 to 1825.

There is a significant amount of content related to the First and Second World Wars, and Anglo-German relations more broadly.

The fonds is arranged into 5 series, grouped by activity: 1 - Correspondence, 2 - Writings, 3 - Subject files, 4 - Personal and financial documents, 5 - Published material.
