The Law Library of Congress has recently announced an archive of legal blawgs dating back to 2007, comprising more than 100 blogs categorized by topic. This is an extremely useful research resource for both legal scholars and students alike. The blogs were selection based on variety, authority (frequenty cited, widely read, awards won, and scholarly nature) and user nomination. Blogs are monitored regularly to ensure that they continue to fit the selection criteria.
Thanks to Wisblawg for this info.
