I have recently discovered that .pdf documents can be uploaded or imported to Kindle. They do not display a front page image, but they are as readable as standard kindle documents. This is a convenient way of carrying lots of scientific papers around without the need to Internet access or a laptop. The system works well on kindle handheld or kindle for PC, which is how I processed these images. Of course, the conversion to kindle hand held reader looses all colour, but that is seldom an issue.
Technology is always moving on and I would expect with the new generation of readers, the colour loss will be corrected.
