There’s an army of volunteers behind the Wilton Library’s Awesome Autumn Book Sale, set for Friday, Sept. 23 through Sunday, Sept. 25.

“During the three days of the book sale, a cadre of 50 to 60 volunteers will straighten the shelves, cashier and assist people. This is in addition to the 100 or so people who tirelessly volunteer each and every week keeping ahead of the donations that are dropped off at the bins on Godfrey Place every day,” said Janet Crystal, marketing communications manager for the library.

The book sale covers tots to teens in the Brubeck Room with board books and picture books to young adult novels. The entire Book Cellar will be open featuring a large assortment of items including fantasy and science fiction, bestsellers and nonfiction and categories such as mysteries, gardening, travel, biographies, cook books, art and more. The items include gently used, new, collectible, rare books, DVDs, CDs, and books on CD. Proceeds benefit the library.

Friday hours are noon to 6, Saturday 10 to 5, and Sunday, 1 to 5. On Sunday items will be half-price.

The sale has a bit of history. Originally it was a children’s book sale that ran the first weekend of December, Crystal said. After several major snowstorms canceled the fund-raisers a few years in a row, the organizers decided to move the sale to September and call it Tots to Teens. As more and more people began to take advantage of the early fall sale, they asked if the library had adult books in addition to the children’s. The Tots to Teens book sale morphed into the Awesome Autumn Book Sale about four years ago and it has been going strong ever since.
