I want to know if there is a name for this, and how to make one LaTeX.
It's a paragraph, usually on the first page of a research paper, that provides information about the publisher and/or the author(s). It seems to be clearly distinct from adjacent text, perhaps it's even a float.
There is an example of what I mean at the first page of this paper, just above the footnote:

Sorry for being unclear, but I have no idea what search terms to use even.
