There are four books in this series, three of which are on Logos already.
The only one that is in a Digital Logos edition is this one:

The other two are in ebook format. Would it be possible to format them into Logos readers editions? It's easier to use if there are page number references and things like footnotes and indexes are more easily accessible.
