In my Fairy Kingdom, writing and reading is considered to be phenomenally important. Literacy rates are perfect - everyone in the realm reads. Okay the material varies from Play Pixie Monthly to serious works on history but everyone has at least one book on the go at any one time.
The realm doesn't officially ban books though it discourages anyone from reading Eileen's alternative history. The classic fairytales are studied at school. Those taking an interest in other worlds, which they may or may not get to explore, tend to read biographies and auto biographies of prominent folk from those worlds. They usually study the geography of those worlds too.
So reading then is considered vital for keeping informed as well as for entertainment. And all of that is just in my fictional creation. Prophecies, usually on scrolls, form an important part of a lot of fantasy novels. Fictional schools, like Hogwarts, have their own libraries. So how is reading treated in your fictional world? Can anyone read or is it limited to those of a certain class? What books are read or banned?
