If you use PACER, please install RECAP
Launched in 2010, the RECAP extension is a free tool for your browser that helps us collect the content you see on CourtListener. Once installed, anything you buy on PACER gets automatically added to the RECAP Archive and anything another RECAP user has bought is automatically free to you.
