The Open Shakespeare package provides a full open set of shakespeare's works (often in multiple versions) along with ancillary material, a variety of tools and a python API.
Specifically in addition to the works themselves (often in multiple versions) there is an introduction, a chronology, explanatory notes, a concordance and search facilities.
All material is open source/open knowledge so that anyone can use, redistribute and reuse these materials freely. For exact details of the license under which this package is made available please see COPYING.txt.
Open Shakespeare has been developed under the aegis of the Open Knowledge Foundation (http://www.okfn.org/).
