Bibliographies with biber and biblatex
This example shows how to automatically generate citations and a bibliography with biblatex and biber.
Biblatex and biber work together to automatically format references and citations like the older cite or natbib and bibtex tool chain, but they offer more powerful and easier to use formatting and better support for special characters (unicode).
For a full list of biblatex styles, see the user guide in the biblatex manual.

LaTeX Coffee Stains
This package provides an essential feature to LaTeX that has been missing for too long. It adds a coffee stain to your documents. A lot of time can be saved by printing stains directly on the page rather than adding it manually. You can choose from four different stain types.

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.
