A large portion of the 184-page ledger was never used. Pages 1- 47 and 181-184 contain technical notes about refrigeration in no apparent order. Entries are predominately for the years 1953 to 1955, but there are a few for 1979. An index section at the front of the book was used to record addresses as well as a few notes. Inserted within the pages were several printed instruction sheets and handwritten notes of a technical nature, assorted newspaper clippings, a wallet-size safe boating guide, and two colour photographs pertaining to family. They have been removed to a separate folder.
