| Custodial History | Prior to passing to the donor, the pamphlets were amongst the personal papers of Mary Hayes, the donor’s late aunt. They were in a postal envelope addressed to Mary Hayes and ink stamped 'C. M. S. Readers' Club'. The postal envelope had been repurposed by the donor; it is not made available for consultation as part of the archive but is held in the Cadbury Research Library deposit file. The papers were accessioned retrospectively in January 2023 . |
