I had this ready to go yesterday but never got near a computer to post it.  So I'm backdating to Friday and life goes on...

“The Prelinger Library is a small privately owned “public library” in San Francisco with the unique philosophy that browsing library stacks can reveal new knowledge, if the books are arranged for browsing. This is counter to most public libraries who rely on computer terminal searching, databases and the Dewey Decimal system to atomize books and subjects, with stack browsing a sort of random after effect. Now a (real) public library in Arizona has joined the revolution and claims to be the first public library in the nation to drop the Dewey Decimal system. Instead, books will be shelved by topic, similar to the way bookstores arrange books. The demise of the century-old Dewey Decimal system is overdue, county librarians say: “People think of books by subject. Very few people say, ‘Oh, I know Dewey by heart.’ “”
