Morgan and Chris talk about the Scribble document authoring format, with Morgan talking about authoring her dissertation in it and Chris talking about writing an OpenDocument Format (sometimes shortened to "ODF" or "ODT") exporter. (That code is now a merge request which will hopefully become part of Scribble itself!)

The Digital Humanities Workshops episode... this is kind of a continuation of those topics.
Racket 7.4 release notes, where Morgan is mentioned as a contributor.
Clarification: At one point we talk about whether or not Scribble includes support for "image lists". It has the relevant building blocks with support for images and figures, we were talking a bit more specifically about fitting a particular document formatting and organizational pattern used in art history papers.
