I own several Visual Quickstart Guides and have enjoyed Sandee Cohen's books for several years now and "InDesign for Macintosh & Windows" is a good reference book to have.
As mentioned, I'm one of those that try to not visit a bookstore because I end up coming out with too many design books (and yikes, you know how much those books can cost).
With InDesign 2.0, there is anticipation for the upcoming Real World InDesign book by Olay Kvern which will be released in September 30th and of course there is Adobe's InDesign 2.0 Classroom in a Book which has been receiving bad reviews due to it's rush release with text omissions and typos galore.
But with this book (which is the cheapest among the InDesign books out right now), Sandee Cohen does a great job. Actually, what made me enjoy this book compared to her other books that I have purchased is that she goes into how she makes books with InDesign and from reading her sidenotes, she has passion for the software even though she has taught Quark for over 15 years.
When the writer shows enthusiasm about the software and also gives 100% in helping the reader understand in preparation for the print side of their work in InDesign, you can't help but enjoy this book.
Many of us who switched to InDesign 2.0 are learning every moment with each product about how cool this software is and this book helps appreciate InDesign even more.
She tackles everything from color, styling, layers, pen and beziers, text effects, pages and books, libraries, tabs and tables, automatic text, typography controls, color management, output and so much more.
Anyway, for those who want an great reference book for InDesign 2, check out this Visual Quickstart Guide.
