Book Exchange From Rosann Fox, a library media specialist at Centennial Junior High School in Casper, Wyoming: ìI have a sure fire way to circulate books. Our library media center purchases students' used paperbacks for the cover price -- with fake funny money. After a week as buyers, the books are organized by genre and displayed for sale to those who possess the fake funny money. Hint--when advertising this event, make sure that you state that you will ëbuyí appropriate books only -- or you will get little brothersí or sisters' discards. The kids love it, moms love the cleaner room, and kids get new books to read.î
