The manuscript viewer is based on the Edition Visualization Technology (EVT). EVT is a software for creating and browsing digital editions of manuscripts based on text encoded according to the TEI XML schemas and Guidelines. This tool was born as part of the DVB (Digital Vercelli Book) project in order to allow the creation of a digital edition of the Vercelli Book, a parchment codex of the late tenth century, now preserved in the Archivio e Biblioteca Capitolare of Vercelli and regarded as one of the four most important manuscripts of the Anglo-Saxon period as regards the transmission of poetic texts in the Old English language.

To ensure that it will be working on all the most recent web browsers, and for as long as possible on the World Wide Web itself, EVT is built on open and standard web technologies such as HTML, CSS and JavaScript. Specific features, such as the magnifying lens, are entrusted to jQuery plugins, again chosen among the open source and best supported ones to reduce the risk of future incompatibilities. The general architecture of the software, in any case, is modular, so that any component which may cause trouble or turn out to be not completely up to the task can be replaced easily.

For more information about how to use and/or customize EVT please refer to the EVT Manual included in the archive you downloaded, in the "doc" folder.

EVT is used in the following projects:

• Codice Pelavicino Digitale
• Vercelli Book Digitale

EVT has a home page in the SourceForge repository, but development is done on Gitlab and Github: if you are interested in learning more about EVT and/or in adapting it to your specific needs please contact the project Director, Roberto Rosselli Del Turco roberto.rossellidelturco@gmail.com.
