Call Before You Visit
The Mayflower Library in Oakland is open for research on most, but not all, Thursdays, between 9:00 am and 5:00 pm.
Please call ahead of time to make sure a dedicated volunteer will be there on the Thursday you plan to visit. We have an answering machine to catch all messages when a volunteer is unavailable. Someone will contact you as soon as possible. But leaving a voicemail will not guarantee that a volunteer will be available on any particular Thursday. Double check with a live person.
The library is also available by appointment. Call the number above when available.
