So people can stop reporting it as a bug on my side.

I tested and it is not working :(

I don't know what you are doing but you're doing it wrong. It's confirmed to be working with both normally enchanted books and books enchanted through NEI in version 109+.

I will try in a new instance

books from the creative tab and from ender io enchanter tested

I see now. I confused the issue with the one that wouldn't let you place a book in the slot at all.

Now it really works.thanks a lot.you are an awesome person.
