What to do with those extra books.

First, consider donating them to the Friends of the Monrovia Public Library. Recycling at its best! The Friends take your books and sell them inexpensively. You can get a charity tax deduction for the donation; do ask for a receipt. The money raised goes right back to the Library for programs and services.  Everything stays right here in town.
