bibtopic – Include multiple bibliographies in a document

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.
