To rate this effectively, we need a dual star system, i.e. one for the stories which would, of course, be awarded five stars and one for the Kindle format, which I would give three stars. The idea of a downloadable complete works is excellent (in fact, when I first saw it, I was stunned into disbelief!) but, like any of these massive compilations, an effective way to navigate them is critical. Unlike a book in which a quick flick back to the contents will help, the Kindle format is not so easy and the lack of page numbers and chapters does not help although the percentage marker is useful. I have the original Kindle, so bear that in mind. I have little doubt that the newer model will have taken observations like this into account.
Reading one book from "cover to cover" is quite straightforward but a much more dynamic and interactive process is required for speedy movement through the collection, e.g. an effective active table of contents.
A great idea in concept but there is some way to go before it is effective in reality. To be fair, it was an early attempt at such a challenging and wonderful facility on a machine which has now improved and, no doubt, will continue to improve and be refined, especially now with the i (and other) Pad formats in competition. However, Kindle needs to do a little more than take over the Eformat files from publishers and I am sure it will. A good idea but ...
PS Computer users can soon become intolerant and fail to see what is actually in their grasp; the faster they work, the faster we want them to work. This complete works was free so beggars should not make too much fuss unless they are trying to improve future variants of what was a ground-breaking concept. All of Tolstoy, Austen, Dickens, Dostoyevsky, Shakespeare ... On a tiny little machine! All at once! Free! Who are you trying to kid!
