The package allows the user to include several bibliographies
covering different 'topics' or bibliographic material into a
document (e.g., one bibliography for primary literature and one
for secondary literature). The package provides commands to
include either all references from a .bib file, only the
references actually cited or those not cited in your document.
The user has to construct a separate .bib file for each
bibliographic 'topic', each of which will be processed
separately by BibTeX. If you want to have bibliographies
specific to one part of a document, see the packages bibunits
or chapterbib.
