PDF documents containing formulas generated by LaTeX are usually not accessible by assistive technologies for visually impaired people and people with special educational needs (i.e., by screen readers and braille displays). The axessibility package manages this issue, allowing to create a PDF document where the formulas are read by these assistive technologies, since it automatically generates hidden comments in the PDF document (by means of the /ActualText attribute or suitable tags) in correspondence to each formula.

This package is used for typesetting exercise or exam sheets. In addition, the exesheet class loads the schooldocs package. The package provides: macros to mark out exercises and subparts, specific settings for enumeration lists, environments for questions and answers, with conditional display, macros for marking schemes with detailed comments.

The willowtreebook class is a simple book class, which the author uses for his lecture notes to be found on his web page Benjamin McKay. It actually just selects options for the more sophisticated memoir class.

Many of David Carlisle's more substantial packages stand on their own, or as part of the LaTeX latex-tools set; this set contains: making dotless j characters for fonts that don't have them; a method for combining the capabilities of longtable and tabularx; an environment for including plain TeX in LaTeX documents; a jiffy to create slashed characters for physicists.

This is a simple package which defines about 140 different colours using XeTeX's colour feature. The colours can be used in bidirectional texts without any problem.

The sidecap package defines environments called SCfigure and SCtable (analogous to figure and table) to typeset captions sideways. Options include outercaption, innercaption, leftcaption and rightcaption.

The Molecular Coding Format (MCF) is a linear notation for describing chemical structure diagrams. This package converts MCF to graphic files using MetaPost.

This is a LaTeX package allowing Feynman diagrams to be easily generated within LaTeX with minimal user instructions and without the need of external programs. It builds upon the TikZ package and leverages the graph placement algorithms from TikZ in order to automate the placement of many vertices. tikz-feynman allows fine-tuned placement of vertices so that even complex diagrams can still be generated with ease.

This is a tutorial for XY-pic, in Portuguese.

This package provides document classes (report and article style) for writing technical reference manuals. It offers a wide left margin for notes to the reader, like some of the manuals distributed by Adobe.

The package aims to help a LaTeX author to keep track of all defined labels by typesetting a complete list of labels wherever the author requests it. (Of course, the user may need to have additional LaTeX runs to get the references right.)

The Neo-Hellenic style evolved in academic circles in the 19th and 20th century; the present font follows a cut commissioned from Monotype in 1927. The font supports both Greek and Latin characters, and has been adjusted to work well with the cmbright fonts for mathematics support. LaTeX support of the fonts is provided, offering OT1, T1 and LGR encodings.

This package allows you to create high-quality publication-ready graphics directly from MGL scripts embedded into your LaTeX document, using the MathGL library.

MathGL is a fast and efficient library by Alexey Balakin for the creation of high-quality publication-ready scientific graphics. Although it defines interfaces for many programming languages, it also implements its own scripting language, called MGL, which can be used independently.

Initally a logbook for me, a person with type one diabetes mellitus, this evolved over time into a TeX project, making it prettier and easier to use. I've made it simple to use, while not forgoing the document's beauty or the speed of input. The logbook, with slight commenting out and editing, could be used as a journal by anybody, although the template and graphing functionality are set up for people using insulin injections and blood glucose teststrips, as well as counting/estimating carbs, protein, and fat.

The package provides facilities to draw Bode, Nyquist and Black plots using Gnuplot and Tikz. Elementary Transfer Functions and basic correctors are preprogrammed for use.

This package provides expandable arithmetic operations with big integers that can exceed TeX's number limits.

TeXstudio is an integrated writing environment for creating LaTeX documents. It makes writing LaTeX comfortable by providing features such as syntax-highlighting, an integrated viewer and reference checking.

Sometimes it is necessary to be able to refer to subexpressions of an equation. In order to do that these subexpressions should be numbered. In standard LaTeX there is no provision for this. The subeqn package solves this. Note that this package is not compatible with the package subeqnarray, but it can be used together with the LaTeX class options leqno and fleqn.

The macros defined in this package are used in papers written in Plain TeX for publication in TUGboat.

This collection provides support for Chinese, with additional packages from collection-langcjk.

This package can help to draw sun path charts using a polar coordinate system.

The package generalises the macro patching commands provided by Philipp Lehmann's etoolbox.

This PSTricks package enables you to produce oscilloscope screen shots. Three channels can be used to represent the most common signals (damped or not): namely sinusoidal, rectangular, triangular, dog's tooth (left and right oriented). The third channel allows you to add, to subtract or to multiply the two other signals. Lissajous diagrams (XY-mode) can also be obtained.

This package provides a derivative of the CV class available to LyX users (renamed to avoid the existing cv package).
