The Friends of the Johnson City Public Library will hold a book sale this weekend featuring quite a few donated items.Friends Book Sale Committee Chair Kathy Hall said, “Our bi-annual book sale is a great place to find an unexpected treasure or just your next great read. We always have a huge variety of adult and children’s books, DVDs, CDs and even puzzles. This sale in particular will feature a large selection of children’s books.” Organizers say all proceeds from the sale will go to furthering the library’s work.
