Akashic Tome: One Book for Every Mod's Manual
The 
Akashic Tome is a single book that gathers the manuals of many mods into one place. Instead of carrying a stack of separate guide books, you carry one item and pick the manual you want from it. That is the whole point of the item: consolidation.
What It Does
Mods often add their own documentation as a book or manual. Each one normally takes its own inventory slot. The Akashic Tome holds those manuals together, so the reading material for several mods lives inside a single book. You no longer need to sort through a pile of guides to find the one you want.
Crafting the Akashic Tome
There is exactly one recipe for this item, and it is shapeless. That means the arrangement of the ingredients in the grid does not matter — only which items are present.
The recipe is:
Book- #c:bookshelves
Place a Book and a bookshelf together in a crafting grid and the result is the Akashic Tome. Because the recipe is shapeless, you can put the Book and the bookshelf in any slots you like and still get the same output.
The bookshelf entry is written as a tag rather than a single specific block. Any bookshelf that belongs to that tag works as the ingredient. If you are unsure which bookshelves qualify, try the one you have on hand and check the result in the crafting output slot before committing your materials.
Why the Recipe Is Worth Knowing
The Akashic Tome costs very little. A Book is cheap to make, and a bookshelf is a modest amount of wood. For that price you get one item that replaces a growing collection of manuals. As you add more mods, the value of that single slot only increases.
Using It
Once crafted, the Akashic Tome is the item you keep with you. Rather than hunting for the right manual in your inventory, you open the tome and choose from the manuals it contains. The individual guide books are still the source of the information — the Akashic Tome is the container that keeps them reachable without the clutter.
Practical Notes
- Keep the Akashic Tome in a hotbar slot or somewhere quick to reach, since it is meant to be consulted often.
- The recipe is shapeless, so there is no wrong layout as long as both ingredients are present.
- The bookshelf ingredient comes from a tag, so more than one kind of bookshelf can satisfy it.
- Because there is only one recipe, there is no alternate path to the Akashic Tome — a Book plus a bookshelf is the only way.
Summary
The Akashic Tome turns a shelf of mod manuals into one book. Craft it with a Book and a bookshelf in a shapeless recipe, then use it as your single source for the guides your mods provide. It is a small craft with a large payoff in inventory space and convenience.
