Did you know you can buy books with blank pages? You can even choose the severity of the discoloration and degree of mottling of the pages. Utter psychopaths.
I know someone who has beautiful 2 story bookshelves with a rolling ladder. The only real books I saw on their massive bookshelves? The hunger games and Harry Potter. So sad.
Which is honestly hilarious and sad, because you can basically just spend a weekend going to estate sales and get a phenomenal amount of gorgeous old books for less than what they probably paid for those fake ones. I've picked up so many cool turn of the century science/engineering books that are sometimes hilariously outdated, but they cost like a dollar or two at most, the majority being like 10/$1, and at the very least look really nice on the shelves if that's all you care about.
