The fonds consists of sheet music belonging to various members of the Burrill and Field famiilies, but mostly Emerson L. Burrill and his wife, Myrtle I. Field Burrill.
Most pieces are annotated with initials or signatures: E.L. Burrill, E.L.B., Myrtle Field, M.I Field, or M.I. Burrill. A few pieces, annotated Ethel L. Field, are assumed to belong to Myrtle's sister, Ethel Louella Field.
Other pieces have no initials, signatures or annotations. It is possible, perhaps likely, that these pieces belonged to Violet S. Field.
The music is mostly sacred and spiritual, but also includes popular and patriotic works.
Note: the annotation on some Burrill pieces appears as if it could be E.S. Burrill. However it is suspected to be a short-hand fancy script for E.L. Burrill. The handwriting is identical and there are no other Burrill family members with the initials 'E.S.'.
