Chapterbib and Bibunits ======================= `chapterbib' and `bibunits' are two LaTeX packages which produce multiple bibliographies in a document. This is no problem for RefTeX as long as all bibliographies use the same BibTeX database files. If they do not, it is best to have each document part in a separate file (as it is required for `chapterbib' anyway). Then RefTeX will still scan the locally relevant databases correctly. If you have multiple bibliographies within a *single file*, this may or may not be the case.
