Each floor in New York City’s Library Hotel is devoted to one of ten Dewey Decimal Classification categories, and the six rooms on each floor contain books from a specific topic in that category. The hotel is near the New York Public Library, where hotel management would probably prefer people to check their books out from. According to one article, book lovers are leaving with more than the towels from their rooms. Perhaps they need to have their 6,000 books catalogued into the honor bar system.
