A few notes on the different versions. The Archive version is a scan of the printed version. The scans are OCR'd to make it somewhat searchable, but the large filesize reflects the fact that it contains text scans. The Project Gutenberg and GITenberg versions derive from proofread and corrected text produced by Distributed Proofreaders. ( https://pgdp.org/ ) The GITenberg PDF is a conversion from EPUB by xvfb.
Archive.org does have a source scan in PDF too.[0]
It would be good then change main link from Gutenberg/GITenberg pages to direct link on Archive.org's PDF.
