Rem Koolhaas designed the stacks of the new Seattle Public Library to spiral Guggenheim-like in order to seamlessly accommodate the linear arrangement of the Dewey Decimal System. But there's a more surprising example of a building built on Dewey: the Library Hotel in New York.
Says their blurb at Cheap US Hotels,
Each Of The Librarys Elegantly Appointed Accommodations Have Been Individually Adorned With A Collection Of Art And 25-100 Books Based On One Distinctive Topic. The Topics Are Organized Throughout The Hotel Based On The Dewey Decimal System, With Floors Dedicated To The Ten Major Categories Including The Arts, Literature, Philosophy, And Language.
(I Guess They Missed The Book On Orthography.) The Library Hotel's own description is a little less wild-eyed:
Designed to feel more like a private club than a hotel, each of the Library's richly appointed accommodations are individually adorned with art and a collection of books that relate to the room's unique theme. Personal service goes one step further as guests may request their room based on their personal interests (subject to availability) such as the Literature floor featuring subjects from Poetry or The Classics to Erotic Literature. Such intriguing room themes offered on the Math and Science floor are Astronomy and Botany. Law, Eastern Religion, Money, and New Media are also among the 60 eclectic themes available on the room menu at The Library Hotel.
Basing their room-numbering scheme on a loose adaptation of Dewey got them sued by the OCLC, fortunately settled in the hotel's favor. I would guess that rooms 800.001 (Erotic Literature) and 1100.006 (Love) get more requests than 600.002 (Manufacturing) or 1000.002 (Almanacs). Do you suppose that rooms 1100.005 and 1200.003 (Paranormal and Occult) are haunted?
