Name of contribution: natbib Author's name: Patrick Daly Location on CTAN: /macros/latex/contrib/natbib/ Summary description: Major revision to natbib package, contributions from Arthur Ogawa for REVTeX License type: lppl
Announcement text: ---------------------------------------------------------------------- Arthur Ogawa has made substantial revisions to the natbib package for the American Physical Society and their REVTeX collection. These are mainly to emulate the features of the mcite package of Thorsten Ohl, which is otherwise incompatible with natbib. All this is to allow the upcoming new release of REVTeX to function properly.
The new features allow references to be merged within the bibliography listing itself. They require special BibTeX style files, provided by the APS.
Patrick Daly has made extensive tests to ensure that the regular features of natbib are unchanged. ----------------------------------------------------------------------
