Check out the following post, from In Custodia Legis, the blog of the Law Librarians of Congress:
Our humble blog made the cut -- which means that you may leave messages to future historians in the comments.
Over the last five years, legal blogs (or “blawgs” = law + blogs) have increasingly become vehicles for legal scholars, practitioners, and observers from across the globe to share information on developments in various areas of law, as well as opinions as to how good or bad those developments are. Intellectual property law enthusiasts, for instance, routinely follow blawgs such as Patently-O and Blog@IPJUR.com, while those interested in business/corporate law may find The Conglomerate and The Becker-Posner Blog to be must-view websites. There are even blawgs following particular courts, such the ECJBlog for the European Court of Justice and SCOTUSblog for the Supreme Court of the United States; as well as blawgs that track the thoughts of some of the world’s most respected law school professors, such as The Faculty Lounge and The Volokh Conspiracy.
The Law Library of Congress has been working since 2007 to archive monthly entries for blawgs such as these, so that the legal events addressed in the blawgs of today may be studied many years from now. This collection is called the Legal Blawg Archive, and a link to it may be found on the Law Library’s homepage.
