The library is a nonprofit corporation open to public use without charge. Support comes from membership gifts, fundraising events, endowment income, and appropriations from the Town of Falmouth. It is a member of CLAMS (Cape and Islands Automated Materials Sharing Network) and SEMLS (Southeastern Massachusetts Library system).
The Library’s collection of books, magazines and newspapers, videos, books on cassette, music CDs, ebooks, and audiobooks totals nearly 40,000 items. It includes four special collections: the Thomas G. Ratcliffe Collection of plays and books on theater and film, local history, maritime books, and non-technical books on all of the sciences. A unique collection of historic paintings by Franklin L. Gifford is also housed in the Library.
The Woods Hole Historical Museum is a subdivision of the same nonprofit corporation. Established in 1977 to bring together people interested in the history and character of the Woods Hole community, the museum maintains an active schedule of exhibits, talks, and special events designed to highlight many aspects of Woods Hole life, history, and culture.
