As this is to be, in part, a retroactive exercise, we will have to use whatever exists.
Indeed. The vast majority of scanning done for DP has been bitonal 300DPI. This provides perfectly adequate images for OCR. While low-dpi grayscale images may look prettier, higher resolution black-and-white images generally OCR better, as well as taking up much less disk space. -- Jon Ingram __________________________________________________ Do You Yahoo!?
