Title says it all.

The village box

In regards to the pokedex I don't expect to be able to open it because it has its own GUI and a bunch of other functions. I just want to store it there.

You can add books to the config files yourself. Even if @GirafiStudios does this by default you'd still need to update/delete your existing config for it to work.

Yeah as Joshie said you can add the book yourself in config/enchiridion/ssp.json.
I just did a release for 1.10.2 the other day adding support for more books, not planning to do any 1.10.2 releases anytime soon, unless it is a major bug.
