This year's editor Jennifer Rohn put together a collection of fifty-two selected blog posts showcasing the quality and diversity of science writing on blogs in 2008. You can see the background story on how the book came about here. You can order the first (2006) volume here and the second (2007) here.
I'll be ordering one copy for myself and one for the collection at work as I think that this is a worthy project to support.
If you want a preview of the contents of the book, links to all the winning posts are here.
I look forward to reading and reviewing the book.
