Multiple Bibliographies with the bibtopic Package

This example shows how to generate multiple bibliography sections with the bibtopic package. Each bibliography section can have its own .bib file. This can be very useful in books or theses, if you'd like one references section per chapter, and also in grant and research proposals. See the package documentation for more information.
