Justia has just launched a Federal District Court Filings and Docket database. beSpacific offers a nice summary:
Another terrific project from the Justia team, this database [still under development] of recently filed Federal District Court civil cases allows users to browse by State, Nature of Suit and Cases, as well as seach by Party Name, jurisdiction, type of lawsuit, and within a given date range. According to Tim Stanley, there are currently "over 300,000 case titles since January 1, 2006, and they are updating [the database] daily."TVC, Law Dawg Blawg, Valpo Law Blawg and BoleyBlogs all have additional information about Justia and its new database.
