The Archives also accepts external donations of material that is significant to the legal profession in Ontario.

The Archives serves as an information resource centre for Law Society staff, the legal profession, and the public.

The bulk of the Archives' holdings are corporate records that document the administration, activities, and functions of the Law Society of Ontario since it was established in 1797.

Virtual exhibits focus on individuals or legal organizations, Osgoode Hall, or interesting items from the archival collection.

The Archives also maintains two display cases, located outside of the Great Library at Osgoode Hall.
