How to unlock the Bookworm achievement in Kingdom Come: Deliverance - Definitive Guide
After this just find books, buy them from scribes, steal them off bookshelves. Some specialists even have books that level the skills they specialize in (the millers for example have thievery related books).
You don't have to read skill books for this, any of the bland old knowledge books lying around will do. Once you read your 20th book the achievement should pop.
Hope this helps,
Let's keep cheevin' together!
Scribes always have a ton of lore books you can flip through really easily.
In order to read books, you must first learn how to read. When you first visit the Bailiff in Rattay during the main quest "Keeping the Peace", you can ask him who can teach you to read. This will give you the side quest "Mightier than the Sword". Complete this quest to gain the ability to read. It will cost you 50 coin and a few days will pass.
Once you can read, you will need to find books. You can buy them from Scribes you encounter or they can be stolen/looted from various places. You should not have any issues finding 20 books to read but can also earn this without technically "reading" the books, because the recipes for the potions count towards this and you don't need to be able to read to learn them.
WARNING: Learning to read before obtaining the trophy Trial-and-error from the "From the Ashes" DLC will void it.
