Does anyone know a way of unlocking the digital rights controls on Kindle books? A year or two ago, I downloaded software which took screen images as the basis for conversion to a pdf file. It was trial software, so there are ugly watermarks over each page. Now, the website has gone, perhaps shut down under pressure by Amazon.
I agree with Phil about certain ethics but, on the other hand, a few of the Kindle books I paid for and downloaded in 2012, somehow expired. It was a real pain to sort it out and be able to read them again. That never used to happen with printed books. I'm keen to convert them all to pdf format in order that I take control, rather than be at the mercy of Amazon.
An application called Calibre will convert ebooks to pdf as long as they are not digitally locked, so unlocking is the first step. Can it be done?
