Citations for ibidem
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
You are on page 3 of your endnotes before you remember that ibid is supposed to end with a period, since it is an abbreviation for ibidem ("in the same place"). What genius decided that it was worth saving a character by this practice no longer matters. What matters is that it is now three-thirty in the morning and you have to retype three pages of notes. Louis Menand, "The End Matter," The New Yorker, October 6, 2003
Origin of ibidem
Ibidem came to English in the mid-1600s from the Latin, literally meaning "in the aforementioned place."
