I don't have any statistics on physical books, but anecdotally the physical books I check out from the library happen to be much older than 2 years and still in good condition -- perhaps survivorship bias combined with my preference in books. For ebooks there's this: > Macmillan’s claim of only making $1.15 per book is incredibly misleading, Potash argued. “Seventy-nine percent expired and were removed from library catalogs because the two-year limit occurred first—not because they were checked out 52 times,” he said. In reality, the average is about 11.5 lends. According to Potash, the cost to the library is $6.07 every time someone borrows a Macmillan book.[1] [1] https://www.vice.com/en/article/pa78wv/one-of-americas-largest-publishers-is-screwing-over-libraries https://www.vice.com/en/article/pa78wv/one-of-americas-large...
