Jinbo-cho, Japan's mecca for book lovers, is undergoing a quiet transformation that will change the way people browse for books.

The district in Tokyo's Chiyoda Ward hosts 45 bookstores for new books and 120 offering rare and secondhand books, with estimated combined holdings of 3 million titles and 10 million books.

An electronic database is now being constructed to catalog these inventories on a Web site for the public.
