The Gentle Introduction is the longest-established comprehensive tutorial on the use of plain TeX.

SyncTeX allows navigating between the TeX source and (usually PDF) output, in both directions, given a SyncTeX-aware front end. It is compiled into most engines and can be enabled with the --synctex=1 option.

This is a package for incorporating the values of Subversion keywords into typeset documents.

This package extends the doc package to cater for documenting non-LaTeX code, such as Metafont or MetaPost, or other programming languages.

The sTeX package collection is a version of (La)TeX that allows marking up (La)TeX documents semantically without leaving the document format, essentially turning it into a document format for mathematical knowledge management (MKM).

This LuaLaTeX package provides a wrapper to use the penlight Lua libraries with LuaLaTeX, with some extra functionality added.

This style file makes the alchemical and astrological symbols accessible in Unicode.

This font family is a modification of cm-unicode fonts, with Arabic support.

This package provides several groups of macros cover different branches of mathematics. Those are useful in preparing teaching material.

Built on top of the xcolor package, this package defines the sixteen colors of Ethan Schoonover's popular color palette, Solarized, for use in documents typeset with LaTeX and friends.

Third parties often change the page numbers without rerunning makeindex. One would like to make the page numbers in the index entries more robust. This bundle provides robustindex.sty and robustglossary.sty, which use the \pageref mechanism to maintain correct page numbers.

The package, as the name suggests, supplies tools to automatically suppress indentations in following paragraphs, specifically those following a particular macro or environment.

The bytefield package helps the user create illustrations for network protocol specifications and anything else that utilizes fields of data. These illustrations show how the bits and bytes are laid out in a packet or in memory.

The package simplifies the process of writing differential operators and brackets in LaTeX. The commands facilitate the easy manipulation of equations involving brackets and allow partial differentials to be expressed in an alternate form.

This Perl script allows the user to extract (and display) elements of the log file.

The luamaths package is developed to perform standard mathematical operations inside LaTeX documents using Lua. It provides an easy way to perform standard mathematical operations. There is no particular environment in the package for performing mathematical operations. The package commands can be used in any environment (including the mathematics environment).

This module provides the finnish style that can be set using \DTMsetstyle provided by datetime2.sty.

The package provides a comprehensive and flexible set of commands for combinations of left and right sub- and superscripts.

The package provides commands to convert CJK characters to Unicode in non-UTF-8 encoding; it provides hooks to support hyperref in producing correct bookmarks. The bundle also provides /ToUnicode mapping file(s) for a CJK subfont; these can be used with the cmap package, allowing searches of, and cut-and-paste operations on a PDF file generated by pdfTeX.

The package provides a simple and easily extensible biblography/citation style for Chinese LaTeX users, using BibLaTeX.

The package provides a number of commands for adjusting memoir output to Serbian style.

This package provides a Perl script that provides support for thumbnails in pdfTeX and dvips/ps2pdf. The script uses Ghostscript to generate the thumbnails which get represented in a TeX readable file that is read by the package thumbpdf.sty to automatically include the thumbnails. This arrangement works with both plain TeX and LaTeX.

This is a re-implementation, for LaTeX, of the original Harvard package. The bundle contains the LaTeX package, several BibTeX styles, and a Perl package for use with LaTeX2HTML.

Harvard is an author-year citation style (all but the first author are suppressed in second and subsequent citations of the same entry); the package defines several variant styles: apsr.bst for the American Political Science Review; agsm.bst for Australian government publications; dcu.bst from the Design Computing Unit of the University of Sydney; kluwer.bst, which aims at the format preferred in Kluwer publications; nederlands.bst which deals with sorting Dutch names with prefixes (such as van) according to Dutch rules, together with several styles whose authors offer no description of their behaviour.

Using the \AtBeginPage hook provided by this package, you can add material in the background of a page. \PageLayout can be used to give page makeup commands to be executed on every page (e.g., depending on the page style).
