Once upon a time, if you wanted to read a book or a short story by one of your favorite authors, you either had to borrow the book from a library or a friend or else you had to go buy it in a store. The key in any of those options is that you had to be physically in the same place as the book. If you lived in a country where that book hadn't yet been published, you may never get to see it. If the book had gone out of print, it might be very difficult to find a copy of the book. These days, you can read out of print books as well as numerous new works by great authors online.
