"Haddocks' Eyes": there's the song, what the song is called, the name of the song, and what the name of the song is called! Or as annotator Martin Gardner puts it: "Carroll is distinguishing here among things, the names of things, and the names of names of things.") However, since there was no cross-reference for "Times Square" on the name authority record and no 670 field justification for the spelling "Time Square," I've determined that this is clearly what's called a typo and I will be notifying OCLC of this in due time by way of their "Authority Record Change Request" form.
(Speaking of bygone times, here's a picture of a "giant mailbox stamp selling booth in Times Square" with Assistant Postmaster Aquiline F. Weierich dispensing stamps from inside the booth. From Wikimedia Commons.)
