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.

This package offers tools to draw simple or barely complex schemes of chemical processes. The package defines several standard symbols and styles to draw process units and streams. The guiding light of the package is the UNICHIM regulation.

This citation style covers the citation and bibliography guidelines of the Kunsthistorisches Institut der Universitat Bonn for undergraduates. It introduces bibliography entry types for catalogs and features a tabular bibliography, among other things.

The package adds reference-page-list to bibliography-items. It does its job without using the indexing facilities, and needs no special \cite-replacement package.

The package supports authors use of consistent typesetting of foreign words in documents.

The package facilitates the use of stealth prefixes for counter names in order to help distinguish between counters from multiple input files. The package also provides a means to generate random counters and save such counter values for future typesetting.

The package enables the user to make reference to division marks (such as book, chapter, section), in the document being referenced, in addition to the page-based references that BibTeX-based citations have always had.

This PSTricks package provides a command \pstPutAbs(x,y) to put an object at an arbitrary absolute (or even a relative) position on the page.

The package uses a text font (usually the document's text font) for the letters of the Latin alphabet needed when typesetting mathematics. (Optionally, other characters in the font may also be used). This facility makes possible (for a document with simple mathematics) a far wider choice of text font, with little worry that no specially designed accompanying maths fonts are available. The package also offers a simple mechanism for using many different choices of (text hence, now, maths) font in the same document. Of course, using one font for two purposes helps produce smaller PDF files.

ijqc.bst is a BibTeX style file to support publication in Wiley's International Journal of Quantum Chemistry.

This is a small wrapper for the expex package, adding ways to define, use, and summarize glossing abbreviations. It also provides commands to refer to examples, as well as some inline formatting commands commonly used in linguistics.

This package provides a Plain TeX macro \figflow that allows one to insert a figure into an area inset into a paragraph. Command arguments are width and height of the figure, and the figure (and its caption) itself. The package does not work with LaTeX; packages such as wrapfig, floatflt and picins support the needs of LaTeX users in this area.
