This link has been making the rounds. San Francisco Public had been having a problem with vandalism. Over 600 gay and lesbian themed books were defaced and left inthe library with slips of paper advertising a bible radio station. The man who did the damage was finally caught, but the library was having a hard time deciding what to do with all the remains of the vandalized books. "Reversing Vandalism" was their solution and is available online and in selected SFO branch libraries. [thanks all]
