Short summary of work to be done before February 1.
We need to do some work on one of our earliest works the Library and Epitome of Pseudo-Apollodorus.

1. Add the Epitome for the surviving part of the Library. The first goal is to see how well we can train a model to replicate the way the summarizer extracts from the larger work. The second goal is to see what we can infer about the missing Library when only the Epitome survives.
2. Add to Frazer, Greek and English, the extra layer of citation found in the Wagner edition. That makes alignment with the Epitome much easier.
3. Best way to add that citation level is to add the Wagner edition.
