Accessories of the world problem

Hello guys! I need help with a crafting knowledge issue in Crimson Desert.
I am trying to unlock the “Addendum/Extension: Accessories of the World” in my Equipment Plan.
I previously obtained “Accessories of the World, Vol. IV”, but I did not read the entire book… :(
so I missed the Addendum/Extension contained in it. I no longer have the book in my inventory, and I guess I sold it..
I have already completed the Circulating Energy Research at the Urdavah Research Institute, so I can no longer obtain the Volume IV book from that research again.
How to get it again?
Thanks a lot!
