I first wrote about Blawgworld 2006 in November, in a post at Legal Underground titled "A Book About Law-Related Weblogs from TechnoLawyer." Back then, you had to register with TechnoLawyer to download the book, which includes posts from 51 law-related weblogs, including Legal Underground and this weblog.
More than 25,000 people have downloaded BlawgWorld 2006, but now it's even easier. Using this link to a pdf version of the book, you can access the book directly without having to register with TechnoLawyer. Once you've followed the link, you can save the book to your hard drive. Or you can just click on the image of the book above and do the same (again, pdf).
