I know that quite a few of you are using my Collection Rules to split your commentaries into technical, historical, expository, etc.
Sometimes you might find it helpful to create commentary collections for specific books of the Bible. Thankfully, Logos' metadata makes that easy. Just use a collection rule exactly like this one:
type:bible-commentary subject:"bible n.t. acts"

Personally, I don't create collection rules for every book in the Bible. Having too many collection rules can slow Logos' start time. I create them when I know I'm going to use them quite a bit. If it's just a one-off, I use the rule with a Quick Collection.
You may also want to combine these two types of collection — that is to create a collection of just your technical commentaries on Acts. Although you can add collections together, there's no simple way to create a collection of all the books that are in both Collection 1 and Collection 2. But it is possible — it just takes an extra step.
The extra step is to create a collection of all your commentaries that are not technical. That's easy — just create a collection for all your commentaries, then drag your technical collection into the "Minus these resources" section.

Once you have that, it's easy to create a collection of your technical commentaries on Acts. Just create a new collection with your Acts commentaries in "Plus these resources", and your "not technical" in your "Minus these resources". If you're ever done boolean algebra, you'll know that a AND NOT(NOT(b)) = a AND b.

If you rate your commentaries, you can use the same method to create a collection of your favourite or preferred commentaries. Create a collection of all resources with 0-3 stars, and another with 0-4 stars (use the rules myrating:<4 and myrating:<5). Dragging one these into the "Minus these resources" column, will mean you only see 5-star or 5- and 4-star commentaries.

I use these collections in a custom passage guide that only shows my favourite commentaries. It's the guide I go to when I'm in a hurry. I have a separate guide that shows all my commentaries for when I want to do more in-depth study.

Of course, if your prioritisation is 100% accurate, then you won't need to do this because your favourite commentaries will bubble to the top anyway. But I tend to prioritise series but rate individual volumes, which means that poor commentaries in a good series will appear before good commentaries in an average series. Restricting the guide to just commentaries I've rated highly helps me see commentaries I might otherwise miss.
You can also create collections of your favourite Bible Dictionaries, etc., in exactly the same way.
