In the comments to the SF MAGAZINES: 2009 Circulation Numbers post, ASIMOV’S editor Sheila Williams kindly expands on her magazine’s electronic sales, and I’m pushing her comment to its own post. Sheila Williams:

Asimov’s has a solid presence on Amazon’s list of best-selling Kindle magazines (usually hovering between the 13th and 17th places). Electronic subscription sales continue to grow. Amazon doesn’t allow any magazine-The New Yorker, Time, The Economist-to carry advertising in their electronic formats. Last Monday (August 2), Asimov’s and the other Dell fiction magazines became available on the Nook as well. B&N doesn’t rank magazines the way Amazon does, but as of right now it looks like we’re third on their list. That will change in five minutes, but it’s a fun start.
