RECAP is an extension to the popular Firefox web browser that gives PACER users a hassle-free way to contribute to a free, open repository of federal court records. When a RECAP user purchases a document from PACER, the RECAP extension helps her automatically send a copy of that document to the RECAP archive. And RECAP saves its users money by notifying them when documents they’re searching for are already available for free from the public archive.
