What puzzles me most is which part of what I have posted you haven't figured out yet. (First, for the vast majority of DP books PG does *not *have the images and if they did they aren't correlated to any page numbers that may or may not be in the text, but that's a detail.) For many of those early texts, Google, TIA, etc. images are available and can be used as comparison sources. You can see that demonstrated at eb.tbicl.org, where most pages have a page number on the right, which when clicked displays the TIA image for that page. On the readingroo.ms wordpress installation I'm currently building the ability to compare the text of one of those oldies, http://www.gutenberg.org/ebooks/1013 using images from here http://www.archive.org/stream/firstmeninmoon00wellgoog#page/n13/mode/1up You apparently wouldn't find that useful?
