Books/resources for 3...Qd8 Scandinavian as Black?

Looking for any good resources on 3...Qd8 Scandi from Black's perspective. Here is what I have found so far. Please add to it, thanks...

1. The 3...Qd8 Scandinavian: Simple and Strong by Lowinger. This is the only book that I could find that is primarily dedicated to this particular Scandinavian.
2. Understanding the Scandinavian by Sergey Kasparov (one chapter out of the seven ... although it is just one chapter, these Gambit books tend to pack in a lot of moves/variations per page)
3. Starting Out: The Scandinavian by Jovanka Houska (8 pages / 2 annotated games)
4. Play the Scandinavian by John Emms (2 pages / 1 annotated game)
5. On chessable, IM Bartholomew has a comprehensive repertoire for Black and GM Colovic has a lighter leaner repertoire.

Andrew Martin's video series on YouTube about the Qd8 line is hands-down the best!

[COMMENT DELETED]

Thanks for the suggestions/advice ... i don't plan to do much opening study, but I am looking to input moves/games/variations from these books into a large database over time as a reference to compare with my own games (to see where I or my opponent deviated and what these authors' or an engine suggests), since I am planning to be consistent and stick to as narrow and simple a set of opening moves as possible.
