All scans updated with flat scans. Also, posted this link to all the scans in the OP, so all scans can be accessed directly.
Definitely appreciate the scans mate, and I'd love to get working on them, but there's still a bit of blurring on then that I wouldn't be able to work out. Like vlad said, laying them flat and putting something heavy on them is a good way to go, but to get
really flat scans, which are what make the best covers, you'll need to put a significant amount of weight on them in addition to the books. What I do is lay them flat the scanner bed, take a small hardback book (ideally you should have one that's about the size of the box itself, and certainly not large enough to touch the sides of the platen), and while the cover is scanning I cross my arms and physically lean on them, putting my upper body weight on top of the book. This gives it enough weight to make sure there are no bends in the middle and also eliminates nearly all blurring on the creases near the spine, and since it's a hardback book it puts even weight distribution throughout the whole box. What you'll end up with is nice clean, flat, sharp scans which, in turn, can make nice clean, sharp-looking covers.
I know it's asking quite a bit, but if you could re-scan with the above method, or something functionally similar, it would produce the perfect scans I need to be able to make covers for them. And thanks again for all your contributions!
