The South End Library staff is holding its annual book sale in Library Park on Saturday, May 21, but needs volunteers to help make their revenue dreams come true. Carrying tables, putting out the (already sorted) books from their boxes, keeping track of the cash, and helping the book lovers find their favorites are among the tasks. Hardcovers will go for $1 and paperbacks for 50 cents. No surcharge for gas..just kidding. Come and enjoy, a book is your best friend: you can take it anywhere and it will not complain.
