With the exception of a few full page photos, most pages are 80% text - 20 % photos (1-3 small photos per page). All the pages were scanned as full resolution tiffs, and have also been saved as 150dpi greyscale jpgs. As a test I have done the first 15 pages (out of 150) without OCR and now have the size down to 7.5 meg. This would equal 75 meg for the enitire book. I have looked at other PDF books out there with roughly equivalent text/image ratio and page numbers and they have been 10-12 Meg in size. These other books are real text and not all image files which acounts for the discrepency. Time is a factor so I will rephrase my request slightly. Would a 75 Meg PDF be unreasonable? What if it was availible by chapter as well? What about if it was availible by request on CD ($1-$3 to cover materials and postage)? Now if I go OCR and convert it to text how difficult will it be?Is there software that would convert the text but leave the layout so it doesn't have to be reformated? What software?Even given Hi-res Tiffs how accurate is OCR? Will I have to spend hours looking for mistakes and correcting them manually (And I will have to ensure accuracy)?</blockquote>
