For the most part, each letter is clearly legible although it isn't as clear as a vector or TrueType font. These are bitmaps of a very old scanned document, so the characters will be a bit rough. Still they should be clearly legible for the most part. There may be some places that are more clear than others, so if you find a sentence or formula that is difficult to read, please write to me and I'll try to touch up the image file in that specific spot. But overall, I think you'll find the document is clear enough to read, once you save the files on your computer in the 2544 x 3299 pixel format they are stored as on the server.
