I have had many questions about the new Free Library that is in front of the library. Maybe this will answer your questions too.
Do I have to leave a book, if I take one? No. You may leave one if you want, but you certainly do not have to.
What do I do with the books that I take? When you are finished reading a book from the free library you may bring it back for someone else to read, you may pass it on to a friend or you may keep it so you can enjoy it again.
What if I am not excited about the selection? Come back as the books change frequently.
If you have any other questions please ask.
