Welcome to Diamond Tiara's Library! (Yes, they actually read.) She likes anything with higher class ponies, mostly ponies living in Canterlot, the Princesses, and of course, herself and her best friend, Silver Spoon.
She also likes anything portraying the blank flanks or their sisters as idiots.

She isn't very literate herself, so she doesn't care much about the quality or grammar.
If you are reading this message, I am currently adding more folders.
