The Library Hotel is a 60-room boutique hotel in New York City, located at 299 Madison Avenue , near the New York Public Library, Bryant Park, and Grand Central Terminal. The Hotel was designed by architect Stephen B. Jacobs.

The hotel boasts a unique organizing principle: each of its ten guest floors has a theme, designated after a major category of the Dewey Decimal Classification , with each room as a subcategory or genre, such as Mathematics or Botany . Other room themes include Erotic Literature , Poetry , and Music . All rooms have a small complement of books and decorations that accompany the theme, with 6000 books overall throughout the hotel.

Because of this classification scheme, the hotel owners were sued in 2003 by the OCLC . OCLC reached an agreement with the hotel enabling the hotel to continue using the Dewey system. OCLC Press Release

Hotel Denouement from Lemony Snicket's The Penultimate Peril was modeled after the Library Hotel.
