# LaTeX Resources

LaTeX is a software system for typesetting documents, especially those containing lots of mathematics.

The following page contains links to LaTeX resources. I will be adding more in the coming weeks; stay tuned!

### LaTeX Packages

Packages extend LaTeX by providing additional features or structures. The following is a list of some packages that I find quite useful.

amsmath
“The amsmath package is a LaTeX package that provides miscellaneous enhancements for improving the information structure and printed output of documents that contain mathematical formulas.” Produced by the American Mathematical Society, this package contains a number of useful features:
• A subequations environment that produces subordinate numbered equations, such as (3.2a), (3.2b), etc., and allows for cross-referencing to a subequation, such as (3.2b), or to a parent group, such as (3.2).
• A \tag command that overrides the numbering of an equation with a tag that you provide.
• A \text command for typesetting a fragment of text inside a mathematical display. This command can be used in a subscript, e.g., $I_{\text{Na}}$, and automatically adjusts the text, Na, to the appropriate font size, in this case \scriptsize.
• And many more mathematical structures.

Whenever I have a document containing mathematics, I always use this package!

graphicx
The graphicx package provides commands for importing graphics prepared by other computer programs into LaTeX documents, and allows for geometric transformations, such as scaling and rotation. Documentation (16 pages): Gzipped PostScript PDF
(This document also serves as the user manual for the color and graphics packages.)
natbib
“The natbib package is a reimplementation of the LaTeX \cite command, to work with both author-year and numerical citations.” This package allows you to “produce numerical citations even with an author-year bibliographic style, something that permits easy switching between the two citation modes.”

### LaTeX-Related Documentation

• The Not So Short Introduction to LaTeX2e
This document gives a brief introduction to LaTeX2e and “should be sufficient for most applications of LaTeX.”

• Using Imported Graphics in LaTeX2e
This document goes into more detail than the graphicx manual on how to import graphics in LaTeX documents.

• Symbols Galore!
(La)TeX provides you with many symbols. Fortunately, someone has brought all of those symbols together in one comprehensive list. The following file gives you list of over 2200 symbols. Warning: it’s 58 pages long!
• BibTeXing
This document describes BibTeX, a program for creating bibliographies to use in (La)TeX. In particular, pages 7-11 of this document describe the standard BibTeX bibliography entries (e.g., article, book, phdthesis) and the associated fields (e.g., author, title, year).
