Thank you so much for this. I've been over there for a while, very interesting. This was scanned and there are many scanning-type errors, more than one would think necessary, but even so, a real find.
Now, when asked where I got the information, I have a link to refer to. Of course my print edition has an index and list of contributors. I haven't found either at the 1911 site. Still, for things before 1910 or so, it's good.
Missing naturally are articles on Yugoslavia, the USSR, WWI, WWII, Vietnam, Mao, Rachmaninov, Stravinsky, lasers, TV, antibiotics, and Pakistan.
