1. Donate your used books to the library. Grapevine Public Library accepts book donations on Thursdays from 10 am to 9 pm, Fridays from 10 am to 6 pm, and Saturdays from 10 am to 5 pm. We do not accept magazines. Please bring your donations to the doors on the south side of the library near the Convention Center. Ring the doorbell located next to the doors and we will assist you. Donated materials may be incorporated into our collections, sold by our Friends group, or recycled. Once donated, materials become property of the library.
