CALI and Cornell's Legal Information Institute have partnered to release freely downloadable e-books for the Federal Rules of Evidence, the Federal Rules of Civil Procedure, and the Federal Rules of Criminal Procedure. The e-books are in .epub form and compatible with iPhones and iPads. The books are based on the rules versions available on the LII site and include advisory committee notes, internal links to referenced rules, and links to the LII's U.S. Code version. CALI's eLangdell site asks downloaders to consider a donation to LII, which published the books. CALI provides a help page for e-book files and downloading.
