[Haskell-cafe] ocr'ed version of "The implementation of functional languages"

I have just embarked on creating a ocr'ed version of the jpeg images that have been made available for "The implementation of functional languages". However, my ocr software is clunky at best and (not surprisingly) it is slow going. It struch me that someone else might also be hard at work doing this and that there is not point duplicating work. Is anyone else doing this? If so, how can I help? Matt
