Frequently Asked Question List for TeX
Bibliographies
Multiple citations
A convention sometimes used in physics journals is to “collapse” a group of
related citations into a single entry in the bibliography. BibTeX,
by default, can’t cope with this arrangement, but the mcite
and mciteplus packages deal with the problem.
mcite overloads the \cite command to recognise a
* at the start of a key, so that citations of the form
\cite{paper1,*paper2}
appear in the document as a single citation, and appear arranged appropriately in the bibliography itself. You’re not limited to collapsing just two references. You can mix “collapsed” references with “ordinary” ones, as in
\cite{paper0,paper1,*paper2,paper3}
Which will appear in the document as 3 citations “[4,7,11]” (say) — citation “4” will refer to paper 0, “7” will refer to a combined entry for paper 1 and paper 2, and “11” will refer to paper 3.
You need to make a small change to the bibliography style
(bst) file you use; the mcite package
documentation tells you how to do that.
Most recent versions of REVTeX (version 4.1 and later), in
conjunction with recent versions of natbib, already contain
support for combined citations and so no longer even need
mciteplus (but mciteplus is more general and will
work with many other class and package combinations).
The mciteplus package adresses many of the infelicites of
mcite. Again, “ordinary” bst files will not
work with mciteplus, but the package documentation explains
how to patch an existing BibTeX style.
The collref package takes a rather different approach to the
problem, and will work with most (if not all) BibTeX packages.
Collref spots common subsets of the references, so if it
sees a sequence
\cite{paper0,paper1,paper2,paper3}
...
\cite{some_other_paper,paper1,paper2,and_another}
it will collect paper1 and paper2 as a multiple reference.
