I've pinched this from another thread. Our member Jsh1120 has supplied this info. For some reason I couldn't get the whole quote though, but this says it all Hope you don't mind Steve.
() Apple has negotiated contracts with several publishers to put their publications into "Newsstand." These include all of the Conde Nast publications as well as others, e.g. New York Times.
() A user cannot eliminate the "Newsstand" or put it into another folder. Like other apps forced on the user by Apple it cannot be eliminated. And since it's a folder it cannot be placed in another folder. (Another of iOS's annoying limitations.) If you don't want to look at an empty set of shelves your only option is to stick it on that back page you never look at.
() If you happen to subscribe to a publication that is part of a Newsstand contract, that subscription will go into the Newsstand "folder." You cannot move it out. (I know this because I've had a subscription to the New Yorker, a Conde Nast publication, for a long time and it's now stuck in Newsstand.)
() If you subscribe to a publication that is not part of a Newsstand contract, (e.g. Washington Post) you cannot put it into "Newsstand." Nor can you put any other "news" app such as Flipboard into Newsstand. Or any other app (e.g. The Onion) for that matter.
