This collection contains materials from the literary and musical (both traditional and filksong) career of Dr. Ada Palmer. Materials include manuscripts from Palmer's science fiction and fantasy novels (published and unpublished), as well as papers, graphics, and other files relating to Palmer's singing activities, most notably as the director of the noted filksong group Sassafras.

A significant portion of the collection includes materials such as con badges, program books, etc., from a number of science fiction and anime conventions at which Palmer has been an attendee, a panelist, a guest performer, and/or an administrator (i.e, Cosplay Coordinator at Anime Boston).

This collection consists of several pages of musical score material composed by Kristina A. Bishoff. The score comes from Bishoff's 2018 'Green Rider: The Original Book Soundtrack', which was inspired by the Green Rider fantasy series by Kristin Britain.
