DIY Book Scanner

Wow, that's interesting. I use the Canon LIDE scanners and they definitely work. I hadn't thought about X-Y resolution being different.

Aw crap! To prove my point, I scanned a ruler in both directions, and carefully calculated the resolution in the images in both directions. They both came out to 600 dpi. Yet, when I display a scanned PDF book on the monitor and hold the real book beside it, I can see that the text looks compressed horizontally. I guess there's something else going on in the conversion process. Anyway, I was wrong about the X-Y resolution being markedly different on my model of scanner. Sorry.
