The collection primarily consists of the Maunders' published works both on their research and explanatory works on astronomy for a more popular audience. Some of these publications bear annotations. There are also some notes on a variety of subjects, a pin-hole camera, a planisphere and some items of correspondence. There is supporting material in the form of obituaries, letters of condolence and subsequent published works on the Maunders and their work.

The minutes cover meetings held from 28 October 1903-25 February 1922. Pages from the Baskerville Club Stock Book, copies of club rules, letters to members, and postal reply cards are tipped into the volume.

The records comprise correspondence, including with speakers, accounts and annual programmes.
