Ask Slashdot: State-of-the-Art In Amateur Book Scanning?

An anonymous reader writes: I have a shelf full of books and other book-like things ranging from old to very old that I would like to turn into PDFs (or other similarly portable format), and have been on a slow-burn quest for the right hardware and method to do so on a budget. These are mostly sentimental — things handed down over generations, and they include family bibles, notebooks, and photo albums, as well as some conventional — published, bound — books from the late 19th and early 20th Century. None of them are especially valuable as antiques, as far as I know; my goals in preserving them are a) to make them available to other people in my family who are into genealogy or just nostalgia, and b) so I can read some of those old, interesting books (et cetera) without endangering them any more than it takes to scan them once. I was intrigued by the (funded, but not yet available) scanner mentioned earlier this year on Slashdot; it seems to do a lot of things right, but like any crowdfunded project, the proof is in the pudding, and the pudding hasn't yet arrived. It's also cheap, and that fits my household budget. What methods and hardware are you using to scan old documents? Any tips you have from a similar project, with regard to hardware, treatment of the materials being scanned, light sources, file formats, clean-up and editing tools, file-size-vs-resolution tradeoffs? In the end, I'm likely to err toward high-resolution scans, since they can be knocked down to size later if need be, but I'd be interested in hearing about what tradeoffs you've found to work for you. One big question that I'd like to have answered: Is there stand-alone Free / Open Source software, or even just cheap software (I am mostly on Linux, by choice, but won't leap onto a sword to keep my Free Software purity) that makes for easy correction of the distortion introduced by camera-based imaging? If I could easily uncurl and keystone-correct pages, then a lot of input methods (even my phone) are suddenly much more attractive. My old Casio camera could do this 10 years ago, but I haven't found a free software desktop utility that lets me turn photos into nicely squared-up pages.
