Demand mixed with a librarian's sense of worth/taste is one approach. There are many others. And libraries do have to choose due to shelf space and publisher agreements. My hackles rise whenever I hear someone tell me what's worthwhile and what's not. But I do recognize practical necessity. I don't believe there's anything magical about the book/text format over electronic/other formats, other than "that's how it's been" up until recently. I would be pleased to see "Fart Proudly" in any library's holdings, regardless of format. https://en.wikipedia.org/wiki/Fart_Proudly https://en.wikipedia.org/wiki/Fart_Proudly
