The librarians of Occupy Wall Street saw their carefully catalogued collection of over 5,000 books and archive of original writing, art and other material from the historic protest destroyed by the NYPD. There were early reports (spun and promoted by the office of NYC Mayor Bloomberg) that the library had been carefully stowed in a nearby lockup from which protesters could claim it. But these claims were overstated — the books were indeed largely destroyed or missing, along with laptops, shelves and other library equipment.
As Xeni mentioned, OWS's librarians are rebuilding, and they're soliciting donations of books for their collection. Tachyon, who publish my essay collections, alerted me to this when they wrote to ask if I minded them donating copies of my books to the effort (the answer was an enthusiastic yes!).
You can donate to the library by posting books to:
