INDIANOLA, MS—According to a report from a pair of bored teens, The Wondrous World Of Fishes was last checked out of the Indianola Public Library on April 17, 1967. "Hey, check it out—this one's been here since '67," Brad McEvoy, 14, told friend Todd Tyler, 13, while trying to find the library book with the longest unborrowed streak Monday. "Dude, that's like 30 years." Despite the disuse, Houghton-Mifflin, the book's publisher, said it stands behind The Wondrous World Of Fishes, calling it "an exciting, educational look at life beneath the sea."
