Newsstand sales of U.S. magazines are continuing to fall.

An industry group says single-copy sales fell 12 percent in the first half of this year compared with the same period in 2008.

Total circulation, including subscriptions, edged down 1 percent.

The figures are being released Monday by the Audit Bureau of Circulations, based on 521 magazines that gave circulation numbers for both years.

The total circulation of those titles stands at roughly 340 million. About 36 million are sold at newsstands and other retailers but account for a disproportionate amount of publishers’ revenue because subscriptions are discounted.
