What I liked most about the book, is that it really broadened my perl horizons. Especially the section "building a toolkit". A great start to using some perl modules that help you get the job done -fast-.

Being someone who has built a variety of spiders/scrapers, I appreciated the insight from the authors, and appreciate finding the info in a consise condensed reference... something unknown to builders (and would-be builders) of crawlers in the past.
