This headline reads like a Bee article. The juxtaposition in the story couldn't be more stunning, and your comment couldn't be more spot-on.
And yet, it'll be lost on scores of people.
In reality libraries routinely “deselect” or cull books from the existing shelved ones to make room, often for seating space for half asleep readers to use their phones and laptops rather than actual volumes.
Also due to cost of cataloging and shelving, most donation books are sold for book sale fundraising or more likely put in the trash compactors in back.
I worked in university libraries from 1969-2017. One perfect example:
I saw on the shelf of incoming new books for processing a donated copy of And That’s the Way It Isn’t: A Reference Guide to Media Bias
by Brent Bozell and Brent H. Baker (1990). Next it was deemed too conservative by librarians and went to the trash outside (not book sale).
Funny true story: A writer went to a library book sale (50 cents and $1.00) and brought a book up to “a librarian” at the checkout table (admittedly ,it may have been a clerk or volunteer he talked to) and said :
“I want to tell you this book was put with the cheap books but I can assure you this is a genuine Ernest Hemingway first edition.” She said, bored, “So, who is Ernest Hemingway?”
