The book I particpated on (Pro WCF: Practical Microsoft SOA Implementation) finally has had the index created. It's getting close to publication date, I'm told January. This has been a long road, actually inception goes back 2 years. Timing is good as we're up to RTM on the content & code.
An index is fundamentally how I judge a book. Generally, tech books you pick up, read in the reading room, but refer back to it for concepts starting at the TOC or the Index.
This one's rich...
