The collection includes correspondence between Juanita Casey and Tim Vignoles, mainly personal in nature, but also with discussions about arranging for the publication of Casey's writings. Casey's letters are candid, and discuss her family, finances, health, horses and dogs, housing moves, joys and frustrations, and writing. The collection also includes Vignoles's administrative files regarding his option on a potential film adaptation of Casey's The Horse of Selene, and collections of Casey's poems, short stories and one play at various stages of drafting.

Some files in this collection contain outdated racist language about Romani people and Irish Travellers.
