The scholarly digital edition was built in 2017 using Drupal and TEICHI (a Drupal module) from a single TEI XML file. Due to security updates and version issues (both with Drupal and TEICHI), the site could no longer be maintained, so it was converted to a basic html, css and javascript site. Some features like search were lost in the conversion.
