The collection consists of documents, sound and video recordings and photographs relating to children’s games and songs, which have been created and assembled by Mavis Curtis in the course of her research. The majority of the material deals with research in schools in West Yorkshire, notably in the Keighley area, but there are also conference papers and fieldwork notes of more general scope.

Correspondence, fieldwork notes, audio recordings and transcripts, and reference and research material relating to Nigel Kelsey's research into folklore and language of primary school children, mainly dating from the 1960s to the 1980s.
