Dot Porter of Penn Libraries created VisColl to visualize collation structures alongside digitized images of manuscript leaves. During the Digital Tools for Manuscript Studies project, the Old Books New Science Lab and Information Technology Services at University of Toronto Libraries built a web-based application based on Porter's model. It produces detailed and downloadable collation diagrams. 

 UofT's VisCodex is downloadable on Github, and VisCodex To Go can be run on your own computer.
