I know I've seen a bunch of agents say they think "alternate world" or "portal" books are overdone (those in which people can travel to a different world, usually a fantasy land, from ours, or can travel from one fantasy land to another, for example the Narnia books, or the Amber series).
And I'm also quite sure that one of the reasons they are often perceived as overdone is because there have been so many famous, influential novels that use this device.
What I'm interested in, is this: what are the top ten or fifteen works (either stand-alone novels or series) of this type? I know what I would choose, but I'd like to see a range of opinions. Perhaps I'll stumble on some great works I haven't heard of yet.
