Throughout the book, you discovered a number of resources that would help you perform some tasks with less effort or faster. In some cases, a product added the special functionality required to make Google Web Services access possible. I usually placed the special products in a separate section or used them to demonstrate a particular type of Google Web Services access. The book also references a number of Web sites that feature special information ”these helpful Web sites normally appear as part of notes or tips. This appendix is an extension of all those special sections, notes, and tips ”it contains a number of helpful third party resources that will make your Google Web Services experience better.
Of course, this appendix begs the question of why these third party products and sites don't appear in the main part of the book somewhere. In many cases, these products fulfill a special need that I didn't demonstrate in the book or they duplicate a functionality that you'll already find in the book. This appendix contains additional information that I thought you would find helpful, but didn't find a place in the main part of the book for whatever reason.
I'm always on the lookout for great third party products, and I like to know about Web sites with helpful information. These sites often appear in my newsletter (sign up at http://www.freeenewsletters.com/). I also provide them as updates to the book on my Web site at http://www.mwt.net/~jmueller/. If you know of a special third party product or Web site that has special information that would help users of this book, please let me know by writing to me at JMueller@mwt.net.
