Some quests require the books for a mod, some give the book for the mod. Additionally, most mod books are provided in the inventory button added by PatchouliButton mod.

I would recommend:

1. remove the book requirements to start the quest chapters (except where the book plays an interactive role in interacting with the mod, similar to blood magic or ars nuveau)
2. remove the books as rewards for starting quest chapters
3. remove botania books from loot chests
4. provide a botania book in the quest that makes the gateway
5. for mods that require books to get into the mod, add a chapter start quest to standardize the chapters. Some chapters being "click to start" and some being "make item to start" gives an inconsistent feel to the chapters.

With the removal of PatchouliButton, this would need re-evaluation. closing for now
