Acommon thread running throughout most of my computer-book–writing career is that I tend to write a book I wish I had had in order to learn a new technology in the first place. Because I must write that book without the benefit of existing models, I begin by doing my best to master the technology, and then I write the book to help other newcomers learn as much as I did, but more quickly and with less pain, anguish, and confusion. To accomplish that goal, I write as much content as I feel is necessary to cover the topic in the depth that my readers require.
As my editor and I began counting the pages I had assembled for these new editions, we discovered that the number of pages far outstripped the printer’s binding capabilities, even in a thicker volume made possible by using a hard cover (the Gold edition). Certainly not all of the words that I had written were so precious that some of them couldn’t be cut. But we were hundreds of pages beyond capacity. To cut that much content would have forced exclusion of coverage of language or document object model vocabulary.
