I don't like that so many interesting books are not on the shelves. When you don't know what to take to read, you flip through the book, skim through it and understand whether you like it or not. But sometimes I walk between the shelves for 2 hours, I can't find anything interesting: either junk that I read 20 years ago, or primitive tabloid reading. But if someone advises me a good book, then they take it out of the vault for me. That is, I would not have stumbled upon it myself.
I don't like the assortment.
