Some 40 books on gay issues were vandalized at a Harvard library last month, doused with what's believed to be urine. An empty bottle was found next to the volumes, add the staff members, who have spent the last two weeks determining the value of the books, which they place at several thousand dollars. The books are too damaged to keep, says a library rep. "Once the urine is poured, they can’t really fix" the tomes. Campus police are treating the matter as a bias crime, the Harvard Crimson reports.
