The Apple Developer Connection has launched its ADC Bookshelf Service. “For an inexpensive monthly subscription fee, developers can search or browse the entire ADC Bookshelf collection — which includes top-rated programmer books on Mac OS X, Cocoa, Java, Perl, PHP, MySQL and other topics — and add up to 10 books to their personalized ADC Bookshelf. Once on their bookshelf, the books are available to the developer whenever needed — all ten for less than the typical price of a single book at a bookstore.
