The Friends of the Cardiff-by-the-Sea Library Book Nook sells donated, used items at low prices and uses the proceeds to support the Cardiff Library. The Friends of the Cardiff-by-the-Sea Library organization was established in 1984, but it was a few years before the library had a Book Nook. The Book Nook has been in its present location since 2003. Renovations to the library are scheduled to be completed in 2011, and the Book Nook will have a new entrance. Currently, the Book Nook is accessible through the Community Room of the library.
Selected items are available for purchase online through librarybooksales.org.
