Lingering in the stacks.

This article presents information regarding used-book browsing in the Internet age. Used bookselling has become a "click and mortar" business, says store owner Doug Wilson, and he's not happy about it. O'Gara & Wilson Ltd. is the city's oldest secondhand bookstore. Joseph O'Gara opened his store in 1936, after having spent time as a bookseller's apprentice, just as Wilson was an apprentice to O'Gara before buying the business in 1996. Like many of Chicago's other used bookstores, O'Gara & Wilson has made an uneasy peace with the Internet, which places even the rarest books within easy reach of anyone, anywhere. Berg estimates that 25% of Powell's sales are online, even though the stores began Internet sales only three years ago.
