The Versioning Machine was a display environment designed specifically for displaying and comparing deeply-encoded, multiple versions of texts, including a robust typology of notes and bibliographic information. It also displayed manuscript images of each version in an applet which provides for several image enhancement features (such as increased/decreased contrast, image enlargement/reduction, etc. In short, it proved an electronic environment for creating a critical electronic edition. The Versioning Machine made its debut at the 2002 ALLC/ACH (Association for Literary and Linguistic Computing/Association for Computers and the Humanities) Conference in Tübingen, Germany, July 2002.
