Hi @terryribb, if I am understanding correctly, you want to simply create multiple collections, which each collection sorted alphabetically. This is possible in Webflow.
Each lesson would be input as an individual collection item record, sorted by the Name field. Take a peek at the video lessons in our help center: http://help.webflow.com/courses/webflow-cms
Here is a good article (thanks @sabanna) from the tips and tips collection, that gives some things to think about when working with “archived” or “older” posts: Blogs Archive concept - Webflow Tips - Forum | Webflow
