Having finally finished Dave Gorman’s Googlewhack! Adventure, I found an interesting reference about the 1911 version of the Encyclopædia Britannica, which found me googling today to find the entire encyclopædia online. It is available in the public domain due to its copyright having expired. One reason why the 1911 edition is so different and considered to be the greatest edition of the Encyclopædia Britannica is because experts in particular areas wrote the articles corresponding to their areas. For example: Henry Ford wrote the article on mass production.
And so I found an OCR’d, non-proofread version of the 1911 Britannica, as well as a Wikipedia entry about the 1911 edition.
