LaTeX is a word processor and a document markup language written in the TeX macro language. It is sometimes used in academia to prepare documents such as dissertations and theses.
Dissertation/thesis packages for LaTeX were last released by the Graduate School in 2002:
The styling contained in these packages met the requirements of the Graduate School in 2001, some of which have since changed. It is the user’s responsibility to compare them to current formatting requirements and update as necessary.
If your LaTeX installation is missing any external packages needed to compile the UT Austin dissertation/thesis packages, it’s possible they may be found on the Comprehensive TeX Archive Network, a contributor-generated repository for TeX materials.
