I'd like to have three authors that use the same footnote for their \thanks identifier (they are at the same university, and don't need separate affiliation notes). I've read one of the solutions proposed in How to write a footnnote attached to the author in a LaTeX paper?, but the last solution (using recalled footnotes) only works for two authors.
So an example: I'd like to have
Author1* and Author2* and Author3*
- University of Podunk, Timbuktoo.
How about the following?
\newcommand*\samethanks[1][\value{footnote}]{\footnotemark[#1]}
\author{Foo\thanks{University of Podunk, Timbuktoo}
\and Bar\samethanks
\and Baz\thanks{Somewhere Else}
\and Bof\samethanks[1]
\and Hmm\samethanks}
The \samethanks either duplicate the previous value or if you give it the optional argument, it uses that value. So Foo, Bar, and Bof have the same affiliation. Baz and Hmm have the same affiliation, different from Foo, Bar, and Bof's.
I ran into this problem often in the past and my solution is like this
\author{Author1\thanks{University of Podunk, Timbuktoo.} \and
Author2\footnotemark[1] \and Author3\footnotemark[1]}
Not really flexible as one has to count but this is the easiest way I know.
\thanksto take an optional argument which sets a counterthanks@#1to the value of footnote, and recall that mark in\samethanksrather than passing in the value offootnoteby hand. – Willie Wong Oct 15 '10 at 18:01Bof\samethanks[1]. I would much prefer if you can sayFoo\thanks[foo]{..}and then refer to it withBof\samethanks[foo]which will be less of a hassle if you ever need to re-order the authors. I was not completely sure how\thankswork (is it really just a footnote environment?), so I wasn't sure if you can just\labelit. Is this clearer now? – Willie Wong Oct 16 '10 at 01:44\thanksuses\footnotemarkand then defines\@thanksas\@thanks\footnotemark \protect\footnotetext[\the\c@footnote]{#1}}I guess you could probably use\labeland\ref, but it hardlyl seem worth it. – TH.
