Announcement text: ---------------------------------------------------------------------- This is a fully reworked and completed release of opcit, the package for footnote-style bibliography.
The package keeps track of what works have already been cited, so that a further citation produces Idem or op. cit. (both of which are customizable, both globally and locally).
New features include a complete bst file; corrections or improvements suggested by users of the first version; cross references between entries and between footnotes; and more. ----------------------------------------------------------------------
