Redwood remains a "membership library" (open to the public) supported by Proprietors, who own shares and pay an annual assessment, and Subscribers, who pay fees.

The Original Collection of 751 titles has grown to a collection numbering more than 160,000 volumes.In 1833 the Library's name was changed to The Company of the Redwood Library and Athenaeum to reflect its expanding role as an educational institution.

Today the Library is open without charge to qualified scholars and researchers and to those making use of the collections.Lectures, exhibitions, fine arts displays, and other educational activities are part of Redwood Library and Athenaeum's continuous offerings to the community.
