to start, I am a crystal developer who is responsible for putting reports on our sales intranet, and I bought this book thinking it could help me with the new version of Crystal. To be fair, the book does a good job of showing you how to create simple reports. Unfortunately, it never moves far beyond that and is not really deserving of the title "complete reference".
Once you get through the basic material on report design, the chapters on distributing reports through the web, ASP, etc. are weak and the sections on other languages are worse-- the code examples are similiar to the projects that come with the product itself. And probably the worst part of it all, is a MAJOR chunk of the book refers to the previous versions of the product (including Crystal Enterprise 8.5, NOT 9) and outdated features with a disclaimer of "this hasn't been released yet, so here is the old stuff". Why would I buy a book with "version 9" on the cover, when it uses filler material from the previous version? It is a sad attempt to bulk up the page count and make you think you were getting something you are not. So in total, if I could rip the book in half, I would keep the first section and throw out the other half. It is still a good reference for report design, but not much else.
