A used book store is having its grand opening in Washington today. ReBook, a project by the Washington Public Library’s Teen Advisory Board, will be open from 9 a.m. to 5 p.m. today in the lower level of the library. The teen group has been organizing the adult and children’s books and making recycled book art for the store. Proceeds from the book sales will go toward teen programming at the libary. There are drinks and snacks to celebrate the grand opening. The store will be open during regular library hours.
