The Origin of Species on the list twice (#8, #138). Why? — Preceding unsigned comment added by 122.108.160.52 (talk) 09:41, 7 February 2013 (UTC)

Because it was published twice in the series, first in 1929, and then again in 1950. #8 is based on the 6th edition of the Origin, and #138 is based on the 1st edition. --Dannyno (talk) 09:53, 23 August 2013 (UTC)
