Earlier this year, something strange began to happen in the world of used books.
A number of used booksellers were seeing really sharp increases in sales.
Some of them would get 20 or 30 orders, one book at a time,
but all from the same buyer within the course of a day or two.

Others would get one order for 50 books or 100 books.
And these are much bigger volume sales than they were used to.
Some of them didn't really even know how to ship that many books at once.
They had never needed to before.
And what kinds of books were being purchased?
First of all, some of these book titles, the fact that these are books at all is kind of incredible.
And the fact that somebody is seeking them out to buy is just as incredible.
