For some players, this could be too difficult, while for some other players, this could be way too simplistic. More variety of pages should be added in for things like revtech design docs. Those should take some specific pages that are for revtech in addition to other pages.
For a much harder version, each book could consist of a number of pages, and each of those pages could be added to the loot tables for scavenging with the rarer books being more rare to find pages from. Then, you would need to find pages 1-10 of Archery for Beginners in order to craft Archery for beginners. This would completely remove the current implementation of generic pages.
While this approach would be more realistic, it would also be potentially prohibitively difficult to get even a single book done. But that should be available as an option.
As for a different version for an easier time utilizing the mod, increasing the drop chance of the torn pages coupled with reduced number of pages needed for crafting would probably be the best approach.
