I've had trouble finding a legible electronic copy of '93 for my ereader.
Both the Kindle and Barnes and Noble versions appear to be created from
optical character recognition (OCR) software output from a poor quality scan,
and they are full of errors.
I finally found a PDF scan of a (the original ?) poor quality scan, which is
still more legible than the OCR versions. Here's how I got it:
1 - go to:
2 - select the first one on the list (Victor Hugo - 1888 - 524 pages)
3 - hover over the "EBOOK - FREE" button; a pop-up appears
4 - select "PDF"; bottom of the pop-up where it says "Download EPUB, PDF "
