The Chicago Citation Style with biblatex
The biblatex-chicago package implements the citation style of the Chicago Manual of Style, 16th edition. In this example, the notes option causes biblatex's autocite command to put citations in footnotes. The package can also produce inline author-year citations in the Chicago style. See the package documentation for more information.
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 Bibliography Example: The natbib Package
The natbib package provides automatic numbering, sorting and formatting of in text citations and bibliographic references in LaTeX. It supports both numeric and author-year citation styles.
The natbib package is the most commonly used package for handling references in LaTeX, and it is very functional, but the more modern biblatex package is also worth a look.
The Mouse's Tale in LaTeX
This example from section three of the LaTeX verse package documentation demonstrates an ambitious use of \indentpattern to create a striking visual effect. In this case it is defined to recreate the famous typesetting of the original Mouse's Tale as it appeared in print.
Background: "The Mouse's Tale" is a poem by Lewis Carroll involving a 'quadruple pun' which appears in his novel Alice's Adventures in Wonderland. It uses typesetting style to create the final pun (it is a mouse's tale typeset in the shape of a mouse's tail).
For more details see the poem's Wikipedia entry.
