Legal Technology Blog features a post, Text-Mining Case Law, by Dr. Adam Zachary Wyner. This post discusses the short history of the currently known what the author calls ‘closed sources’ of case corpora, Westlaw and Lexis Nexis, the subscription based proprietary services, in contrast to ‘open source’ case corpora and open source search tools. This article stretches the importance of access while pointing to almost unaffordable services provided by the two giants, Westlaw and Lexis, while it features the first attempts of open source case corpora, such as public.resource.com or the decisions from United States Courts of Appeals available online.
