I recommend supporting local independent bookstores; if you want to buy my and Josie Wernecke's The VRML 2.0 Handbook, published by Addison-Wesley, try ordering it through a local (non-chain) bookstore. If your local bookstore can't or won't order it for you, you can buy the book from Amazon.
For more about VRML, see my VRML pages, which include the example files from the book. Sadly, the Tenochtitlan model from the book is not currently available online.
Note that the Handbook has been out for eight years now, an eternity in Internet time. If you want the latest and greatest developments in 3D graphics, it may not be the best choice of book.
