The limited access to Canadian court documents available for decided cases on WestlaweCarswell's Litigator is pretty cool. I have to say though, that the US courts PACER system is even better.
The PACER Service Center is the Federal Judiciary's centralized registration, billing, and technical support center for electronic access to U.S. District, Bankruptcy, and Appellate court records.
PACER (Public Access to Court Electronic Records) is the go to site for extremely cost effective electronic access to the procedure cards, and often, the digitized content of the ongoing court record for a small fee of 8 cents a page. Very Cool! Even more cool is notice from the Law Librarian Blog about a PACER recycling site.
Now the cool stuff that others have gathered for a fee can be retrieved for free through digital recycling. This service is organized by public.resource.org an a memo about this service can be read here. It is always nice to read about people sharing.
