Astrosym is a font containing astronomical symbols, including those used for the planets, four planetoids, the phases of the moon, the signs of the zodiac, and some additional symbols. The font is distributed as Metafont source.

This LaTeX package generates a completed standard form 298 (Rev.: 8-98) as prescribed by ANSI Std.: Z39.18 for report documentation as part of a document delivered, for instance, on a U.S. government contract.

The Plain TeX program (typed in the shape of the towers of Hanoi) serves both as a game and as a TeX programming exercise. As a game, it will solve the towers with (up to) 15 discs.

This small package aims to provide two simple commands and many options to easily write linear operators as they appear in many-body physics, quantum theory, and linear algebra, in any of the ways commonly in use.

The file processes to produce (real) rulers; the author suggests printing them on transparent plastic and trimming for use as a real ruler. The rule widths are 0.05mm, which can be challenging for (old) laser printers.

The basic operations (addition, subtraction, multiplication, division, power to an integer) are implemented by TeX macros in this package. Operands may be numbers with arbitrary numbers of digits; scientific notation is allowed. The expression scanner is also provided.

Instead of having to transform the common source into program or documentation, the central idea was to develop a method to have one common source which can be interpreted by a Prolog system as well as by LaTeX.

The package defines commands that create macros for typesetting vectors, matrices and functions, in a logical way. For example, logical indexing can then be used to refer to elements or arguments without hard-coding the symbols in the document.

The package contains commands for students and teachers of introductory physics. Commands for physical quantities intelligently handle SI units so the user need not do so. There are other features that should make LaTeX easy for introductory physics students.

The EMISA LaTeX package is provided for preparing manuscripts for submission to EMISA, and for preparing accepted submissions for publication as well as for typesetting the final document by the editorial office.

This package provides a LaTeX environment numcases to produce multi-case equations with a separate equation number for each case. There is also a subnumcases environment which numbers each case with the overall equation number plus a letter.

This package provides a cult Greek font from the eighties, used at the University of Crete, Greece. It belonged to the first TeX installation in a Greek University and most probably the first TeX installation that supported the Greek language.

The package defines the \efbox command, which creates a box just wide enough to hold the text created by its argument. The command optionally puts a (possibly partial) frame around the box, and allows setting the box background colour.

These are the Computer Modern fonts extended with Russian letters, in Metafont sources and ATM Compatible Type 1 format. The fonts are provided in KOI-7, but virtual fonts are available to recode them to three other Russian 8-bit encodings.

This package is a rewrite of the multibibliography package providing multiple bibliographies with different sorting. The new version offers a number of citation commands, streamlines the creation of bibliographies, ensures compatibility with the natbib package, and provides other improvements.

The package provides virtual fonts and LaTeX support files for mathematical calligraphic fonts based on the rsfs Adobe Type 1 fonts, with the slant substantially reduced. The output is quite similar to that from the Adobe Mathematical Pi script font.

With pxpic you draw pictures pixel by pixel. It was inspired by a lovely post by Paulo Cereda, among other things (most notably a beautiful duck) showcasing the use of characters from the Mario video games by Nintendo in LaTeX.

The package provides a Unicode font with over 4,000 symbols to supplement the Unicode math symbols. It is compatible with and complements the AMS STIX2 math fonts, but focuses on new symbols and symbol variants more suited to work in logic.

The package is designed to produce from BibTeX or BibLaTeX bibliographical databases the different indices of authors and works cited which are called indices locorum citatorum. It relies on a specific \icite command and can operate with either BibTeX or BibLaTeX.

The pecha class provides an environment for writing Tibetan on LaTeX2e in the traditional Tibetan Pecha layout used for spiritual or philosophical texts, using the cTib4TeX package. It provides features like headers in different languages, page numbering in Tibetan and more.

The macros enable the user to draw simple circuit diagrams in the picture environment, with no need of special resources. The macros are appropriate for drawing for school materials. The circuit symbols accord to the various parts of the standard IEC 617.

This package, initially based on pxfonts, provides many fixes and enhancements to that package, and splits it in two parts (newpxtext and newpxmath) which may be run independently of one another. It provides scaling, improved metrics, and other options.

This package provides a package to scale a document by sqrt(2) (or by \magstep{2}). This is useful if you are preparing a document on, for example, A5 paper and want to print on A4 paper to achieve a better resolution.

The reason for the creation of the tasks environment was an unwritten agreement in German maths textbooks (especially (junior) high school textbooks) to organize exercises in columns counting horizontally rather than vertically. This is what the tasks package helps to achieve.
