For what it may be worth, a couple of years back, one acquaintance of a great nibling (both of them were university students at the time) created a program for his Mac that paged through a textbook downloaded from Amazon and took a screenshot of each page. Those images were OCRed and used to generate a PDF file with the OCRed text layer being used to allow search and the page images being used to display the pages. From what I was told, an 1200 page textbook took ~30 minutes to grab the images and about 1 hour to generate the PDF from them plus any manual cleanup that might be needed.
This did not require removing DRM from the file since that was taken care of by the Amazon app that displayed the book on the computer screen.
