Understanding collation is an important part of studying material texts. However, current tools for representing this information, such as collation formulae, can provide obstacles to accessibility. The Collation Visualization project (VisColl) helps to remedy these issues by providing a means of visualizing a codex’s collation via a digital model. In this project, I created models for 39 codices held by Penn Libraries using VCEditor, the software implementation of VisColl. I then helped prepare the models for upload to ScholarlyCommons, University of Pennsylvania’s open-access institutional repository, and created documentation to assist future VisColl contributors.
