Times change, as David Allen notes in a Daily Bulletin article:
One of the Inland Valley's few remaining used bookstores is closing its doors. The Book Exchange, a used book store at 4847 Arrow Highway in Montclair, has been in business for 30 years, said owner Luisa Conner, who bought it in 1997. The last day of business is Saturday.
The closure of a used bookstore is no surprise.
Conner said her store was affected by the shift to online sales and e-reading, the same factors that have hurt other bookstores.
So what happens to the books?
After the close of business Saturday, remaining books will be boxed up and donated to libraries.
This assumes, of course, that the libraries (a) are still around, and (b) if they are still around, that they're actually stocking deadwood books.
