"The Five Foot Shelf". Those were once a common set of books. They'd show up in used bookstores. Back when there were bookstores.
More than 45 years later, I've read maybe 70% of the books in the list (maybe more), but all in different, more readable editions. Today almost everything I read is in epub, and pdf for technical and scientific papers.
Shouldn't it be "used-book stores"?
