Jureeka! Creates Links to Cases, Statutes, etc. in Ordinary Webpages
Jureeka! is a new Firefox add-on that looks for legal citations in ordinary web pages and turns them into hyperlinks that lead to a free version of the cited source. Pretty nifty. You can download it at the Jureeka! blog, but you'll need to register first.
It apparently works for statutes, case law, regulations, federal court rules, international law sources, and more. See source coverage spreadsheet for a complete listing.
Jureeka! also has a toolbar which allows you to search for source material by legal citation and to find HTML versions of PDF pages.
