The minute books cover committee meetings and general meetings of the Peterborough branch of the English Association 1923-1928 and the PLS 1928-1972 and are the fullest source of information about the PLS in the collection. They include a record of works read or discussed at meetings and the subject of lectures, as well as summaries of income and expenditure and membership registers.
Financial and business papers consist chiefly of invoices and receipts relating to the hire of premises, advertising meetings, and printing.
The files of correspondence deal chiefly with guest speakers and prospective speakers and are fullest for the 1940s and 1950s, when the Society appears to have been able to attract the interest of a number of contemporary writers and critics. There is some evidence that this may have been due in part to the Society's links with L.P. Hartley. Leslie Hartley himself addressed the Society more than once.
Programmes relate chiefly to those meetings addressed by guest speakers, and to which the public was admitted. Speakers included: Sir Osbert Sitwell, Pamela Hansford Johnson, Clifford Bax, E.M. Delafield, and Louis Macneice.
The majority of documents relating to Peterborough Arts Council, of which PLS was a member, date from the period 1949-1953. They include copies of the draft constitution, agenda and minutes of meetings, accounts, and papers relating to a proposed Arts Centre,1949, Peterborough Arts Week, 1951, and Peterborough Arts Festival, 1953.
