By "semi-commentaries" I mean resources whose contents are already divided into sections that correspond to Bible passages, even though the books themselves are not Bible Commentaries in the strictest sense of the term. Here is a short list of examples:
4,000 Questions and Answers on the Bible, https://www.logos.com/product/7300/4000-questions-and-answers-on-the-bible
The Great Texts of the Bible, https://www.logos.com/product/8527/the-great-texts-of-the-bible
Hard Sayings of the Bible, https://www.logos.com/product/742/hard-sayings-of-the-bible
The Prophecy Knowledge Handbook, https://www.logos.com/product/600/the-prophecy-knowledge-handbook
When Critics Ask: A Popular Handbook of Bible Difficulties, https://www.logos.com/product/8810/the-norman-l-geisler-apologetics-library
Everyone would recognize that these are not Bible commentaries in the traditional sense of the term, but it does seem that they should be included in the passage guide somehow by default. If I am studying a passage and a book in my library has a section dedicated to discussing that passage, Logos should be smart (integrated) enough to point me to it. The "obvious" solution would be to change the resource type from monograph to Bible commentary, but this would eventually "junk up" the commentary section with resources that are not technically commentaries.
The "official" workaround is and has been to add these books to a collection and then add the collection to a custom passage guide. It is a passable solution, but it is not ideal and must be done on a per-user basis. Another idea, which I think would be better, is to add these sorts of resources to a brand new section of the passage guide (maybe call it "related material," "from your library," etc.?). If anyone has any suggestions regarding a better solution, please post it. Also, please feel free to add to my list of examples, as I was intentionally trying to be brief rather than comprehensive.
