Ravel, a search visualization, analytics, and annotation platform of United States Supreme Court and Circuit Court cases, now offers free and unlimited access directly through the website (in beta mode). The database, according to its founders, is generally as comprehensive and up-to-date as Google Scholar (meaning complete Supreme Court collection & Circuit Court coverage back to ~1950). They expect to add California, New York, and Delaware case law during the summer.
According to a story from the Daily Journal (“Entrepreneurs use design to launch legal startup,” December 31, 2012) founders Dan Lewis and Nik Reed
. . . set out to create a website that would visually map out case histories so legal professionals could more easily extract important information, such as how many times a case had been cited and what cases incorporated similar key words and phrases.
Co-founders Dan Lewis and Nik Reed are Stanford Law School alumni and their company is discussed in a recent article from the Stanford Lawyer, “The Cutting Edge:
A Positive Disruption: The Transformation of Law Through Technology.”
