They might not be as riveting as Guitar Hero, but the games in the Library Arcade can actually help you develop your library skills. The first game is "I'll Get It," where you take the role of a librarian helping students find the right research materials. In the second game, "Within Range," you must shelve books according to their LC call numbers, but hurry - the clock is ticking! Graduate students from Carnigie Mellon's Entertainment Technology Center developed the games.
