The bulk of the collection spans the period from the beginning of Foss' Oxford University Press career in 1921 to the time of his death. Records dated after this time relate to the Double Crown Club and were added to the collection by Hubert Foss' brother, Christopher Foss, who kept up the connection with the club and continued to gather material, and daughter Diana Sparkes, who created facsimiles of material to add to the collection.
The focus of the collection is on records accumulated through his role as a Double Crown Club member. Approximately one third of records were accumulated through his roles at the Oxford University Press and Henderson and Spalding printing company or through the activities of his professional life in general. Amongst these records there is a focus on the printing of music.
The collection includes correspondence, publications, privately printed books, booklets and leaflets and handwritten notes relating to business matters, history, key personalities and techniques in printing. It also includes examples resulting from different printing methods, including an extensive set of menus designed by members of the Double Crown Club, and other memorabilia.
