I get Newsweek, Entertainment Weekly, The Economist, and Sports Illustrated, Esquire, seems like you could save a lot of trees if these just showed up on your Kindle, anyone heard how long until these are readily available?

My boss has a Kindle. He wants to be able to save his New York Times papers indefinitely. He’d also like to be able to choose certain issues of other papers for unlimited amounts of time. So far I can only find that it auto saves for 7 days. Any ideas?
