The other day, I found this at WeirdStuff:
Click on the image above for the PDF. It is the original scan, but it is fully searchable in your favorite PDF reader, you can extract text, and the entries in the table of contents are hyperlinks.
I know Craig Bruce has scans online, but I find searchable PDFs a lot more useful than single images on a website. Search engines are even going to index this issue!
Some background: The pages have been downsampled to 196 dpi (which was the native resolution of the press) to get rid of MoirĂŠ patterns. The color pages have been converted into CMYK, and every channel’s curve has been adjusted to get rid of unwanted parts of the histogram. All images are JPEG compressed greyscale – while this is not optimal for printing (although you can scale the images up and then convert them to B/W with quite good results), it looks better than monochrome/G4 in most viewers, and works well with pages that combine text and graphics. I’m open to input on how to improve the quality or get the size down more.
