Airports see healthy used book trade

Here's an interesting story in the Chicago Sun Times about used book sales at airports.

In North Carolina, it's a reader's paradise at Raleigh-Durham International. New books are sold at Borders, Hudson News & Books, CNBC, Press Plus and other retail outlets.

But there are about 8,000 used books for sale at 23-year-old 2nd ed. Booksellers, a shop owned by Walter and Karen High.

Walter High says the shop sells about 60,000 books a year.
