Quotes
Like bats in caves, there are words which nowadays live almost entirely in the semi-darkness of footnotes. Ibid (short for ibidem) is one, denoting a reference to a work already quoted, a function also performed by op cit (work cited) and its cousin loc cit (much the same).
-- David McKiein, "Step Forward, All Friends of the Footnote," The Guardian, August 21, 1996
Origin
Ibidem came to English in the mid-1600s from the Latin, literally meaning "in the aforementioned place."
