As you may know, it's become custom recently for the folks who have memberships (attending or not) to the upcoming Worldcon to get free copies of most of the nominees, so that they can all be checked out before it's time for voting. Even better this year, however, is that all five of the nominees for the Short Story Hugo are already free on the web, so why not have a look and enjoy?
