Citing the same reference twice includes a copy rather than a duplicate of the reference number

[Rick Muller]

I think I'm doing something wrong in the way that I'm citing references in tufte-latex.

I have a set of notes that I'm writing in which I want to cite multiple literature references, often multiple times each.

I have a paragraph that might look like

Lorem ipsum dolor sit amet \cite{Ref1}, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat \cite{Ref2}. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum \cite{Ref1}.

I would like the second citation to Ref1 to simply be the number of the reference inserted into the text for the first reference to Ref1. However, tufte-latex inserts a duplicate reference. How do I get it to insert the original reference number?

Thanks in advance,

Rick
