for the 1st one, A Cumulative Index to the Grammar and Syntax of Biblical Hebrew, couldn't this entire work be created today by running a search? So the script says "go through entire Tanakh verse by verse and search for that reference in all the grammars the author sites" -> format nicely?
- Yes, Logos does this for you -- but only for grammars you own. So this book could possibly inform you of additional information when you're doing studies on a particular passage but none of your grammars discuss it. Unfortunately, its citation format is incredibly terse; there are no clues about what the grammars say about the passage, so you cannot use this as any kind of substitute for the grammars themselves. Probably Logos would profit by buying this book for all their users and publishing it as a dataset :).
