Q. While developing a bibliography, I came across a book whose title was different for the first edition than for later editions. How should this be indicated in a bibliography?
A. First, cite the edition that you consulted. For example, a bibliography entry for the fourth edition of Garner’s Modern English Usage, published under different titles for the first three editions, would look like this:
Garner, Bryan A. Garner’s Modern English Usage. 4th ed. New York: Oxford University Press, 2016.
Then, add the info about the other title(s) to the end of the entry:
Garner, Bryan A. Garner’s Modern English Usage. 4th ed. New York: Oxford University Press, 2016. Earlier editions published as A Dictionary of Modern American Usage (1st ed.) and Garner’s Modern American Usage (2nd and 3rd eds.).
