My father is giving away one of his prize possessions: the 11th edition of the Encyclopedia Britannica, published in 1911.
According to my father, this was known as the “scholars edition” because it was the last edition that could be used as a primary resource. For example, the article on penicillin was written by Alexander Fleming; the article on Communism was written by Leon Trotsky.
The taker would have to pay the postage if they wanted it shipped to them. That would be substantial since technically the 11th edition had 33 volumes, though I don’t know if my father has all the supplements. If a library wanted it, my father would consider paying for the shipping.
The volumes are not bound uniformly. My father assembled the collection over the course of years, and the books come from at least two different printings.
