I created this simple macro, for citing papers. Basically just use this format: \turabian{bibtextkey}{page range} or \turabian{smith1980}{10-23} ...and it places a citation. Now, one feature I needed was if the bibtextkey ever repeated, it should instead display "Ibid. p. 10-23" So if I have text like this... This is a passage about some trees. The trees were tall. \turabian{smith1980}{2-30} The trees were also really green.\turabian{smith1980}{40-44} ...the second citation just displays the "Ibid., p. 40-44". I did this by at the end of the macro, setting \setvalue{previousmymacro}{#1}, then checking if that value is the same the next time hte macro is called. So its just checking, if #1 is same as last time the macro was called, then use Ibid. Something though isn't working as expected. Why isn't this displaying Ibid. when it should for repeated bibtextkeys? --Joel Code: \let\previousmymacro\empty \define[2]\turabian{% \iftok{#1}{\getvalue{previousmymacro}}% \doifemptyelse{#2}{% \footnote{Ibid.}\nocite[#1]% }{% \footnote{Ibid., #2.}\nocite[#1]% }% \else% \doifemptyelse{#2}{% \cite[#1]% }{% \cite[loctext={#2}][#1]% }% \fi% \setvalue{previousmymacro}{#1}% }%
