O’Reilly Media today announced the release of iPod & iTunes: The Missing Manual, Fourth Edition, by J.D. Biersdorfer. The 328-page book (US$24.99 retail) offers tips, tricks, and information on the popular digital media player and Apple’s iTunes software. “Like the device itself, this book is a long-running bestseller, now in its fourth edition. What makes it so popular is the wealth of useful, accessible information it provides– especially since Apple doesn’t supply a manual of its own. Fully updated, iPod & iTunes: The Missing Manual gives you everything you need to evolve with each new version of iPod and iTunes.”
