Textus is a toolbox and web application for working with and presenting textual material from shakespeare to schopenhauer, and letters to literature.

Textus represents the evolution of more than 6 years of software development, building as it does on the OpenShakspeare platform (which powered http://openshakespeare.org from 2005 until 2011) and the OpenCorrespondence system (which powered http://opencorrespondence.org from 2009-2011).
