(From my enormous backlog of Things to Blog On.)
In The Atlantic of December 2013, a letter (p. 13) from Tom Bourne of Woodstock VT:
The word sic is used to indicate an incorrect word in a quote. Why, then, does Karl Greenfeld use it after a perfectly correct its? I can only assume someone thinks its should be it’s here: “We have also to read 79 pages of Angela’s Ashes and find ‘three important and powerful quotes for the section with 1-2 sentence analyses of its [sic] significance.’ ” The possessive its is fine just the way it is. I’ll bet both Greenfield and his daughter know that. How about your proofreader?
The Copy Desk disputed this in a reply; see if you can anticipate its content. And then we’ll talk a bit about the perils of [sic].
