In the flesh, it's a novel of nearly a thousand pages that includes footnotes. An impractical proposition for a coat pocket when travelling on the tube, but fine on the Kindle. I was also pleased to see that the footnotes work seamlessly on the digital version.
I've discovered that Project Gutenberg supports the Kindle Mobi format as well, though I haven't downloaded anything from it yet, but maybe it is always worth paying for a professional port. I've got a free e-book of Kipling's Kim but it is practically unreadable due to mad stuttering line breaks.
