There three (that I know of) books by Ralph Dale Davis on the first 37 Psalms which follow the Psalm format. Two of them are classified as monographs an one as a biblical commentary.
The three resources are setup as Logos Research Editions, are setup with the same indices and setup with the same search fields. They should all be of type Bible Commentary.
Not only this but even though there is no official series title they should be grouped as a series. I've added my own. Reading the blurb for the fastest resource it is clear the publisher / author intended these resources to form part of a 'loose' series.
So fixing up the type to make it consistent and assigning a series title to these three resources, FL could then bundle them together and promote the bundle in order to attract sales of the older titles for those who only have the latest title and might not be aware of the older two titles or vice versa.
