These packages are either mandated by the core LaTeX team, or very widely used and strongly recommended in practice.

This package provides some commands useful to correctly write the logo of Gruppo Utilizzatori Italiani di TeX (Italian TeX User Group), using the default document color or any other color the user may ever choose, in conformity with the logo's scheme as seen on the group's website https://www.guitex.org. Likewise, commands are provided that simplify the writing of the GuIT acronym's complete expansion, of the addresses of the group's internet site and public forum, and the meeting GuITmeeting and the magazine Ars TeXnica's logo. Optionally, using hyperref, the outputs of the above cited commands can become hyperlinks to the group's website https://www.guitex.org. The Documentation is available in Italian only.

Erewhon is based on the Heuristica package, which is based in turn on Utopia. Erewhon adds a number of new features --- small caps in all styles rather than just regular, added figure styles (proportional, inferior, numerator, denominator) and superior letters. The size is 6% smaller than Heuristica, matching that of UtopiaStd.

The Cherokee script was designed in 1821 by Segwoya. The alphabet is essentially syllabic, only 6 characters (a e i o s u) correspond to Roman letters: the font encodes these to the corresponding roman letter. The remaining 79 characters have been arbitrarily encoded in the range 38-122; the cherokee package provides commands that map each such syllable to the appropriate character.

This package establishes a simple and easy-to-use LaTeX template for Tsinghua dissertations, including general undergraduate research papers, masters theses, doctoral dissertations, and postdoctoral reports.

This package provides a LuaLaTeX package to draw pixel-art pictures using TikZ.

This package provides a collection of packages containing: accenti, dblfont, envmath, evenpage, graphfig, mathcmd, quotes, and sobolev.

This package enables the visualization of seating charts, whereby the seating layouts (i.e., the arrangement of seats in a room) and the seating scheme (i.e., the selection and labeling of occupied seats) can be controlled independently of each other.

The package characterises and defines the author's B1 encoding for use with LaTeX when typesetting things using his Bookhands fonts.

This package provides a set of fonts that extend the txfonts bundle with small caps and old style numbers, together with Greek support. The extensions are made with modifications of the GNU Freefont.

The Latin Modern fonts are derived from the famous Computer Modern fonts designed by Donald E. Knuth and described in Volume E of his Computers & Typesetting series.

The package the creation of references to multiple bibliographies within one document. It thus provides complementary functionality to packages like bibunits and chapterbib, which allow the creation of one bibliography for multiple, but different parts of the document. Multibib is compatible with inlinebib, natbib, and koma-script.

The package simplifies production of custom shapes with correct anchor borders, in PGF/TikZ; the only requirement is a PGF path describing the anchor border. The package also provides macros that help with the management of shape parameters, and the definition of anchor points.

The bundle provides a template for UNAM's College of Engineering Theses.

BibTool manipulates BibTeX files. The possibilities of BibTool include sorting and merging of BibTeX databases, generation of uniform reference keys, and selecting references used in a publication.

The package provides commands to draw and annotate various kinds of timing diagrams, using TikZ.

This template is for theses at Southeastern University, Nanjing, China.

The Math Design project offers mathematical fonts that match with existing text fonts. To date, three free font families are available: Adobe Utopia, URW Garamond and Bitstream Charter. Mathdesign covers the whole LaTeX glyph set including AMS symbols. Both roman and bold versions of these symbols can be used. Moreover, there is a choice between three greek fonts (two of them created by the Greek Font Society).

The package allows you to input (subsections of a) file, print them in verbatim mode, while automatically breaking up the input lines into pieces of a given length, which are output as figures. These figures are posted using the [H] specification, which forces LaTeX to place the figure at the spot of invocation, rather than floating the figures to the top of the next page.

Active-conf is a class for typesetting papers for the Active conference on noise and vibration control. The class is based on article with more flexible front-matter, and can be customised for conferences in future years with a header file.

This package provides key-value style author and affiliation information tagging in a structured format. Each field has a specific name within \author and \affil commands similar to BibTeX format, and can be customized individually.

The package provides tools for inserting nonbreakable spaces after nonsyllabic prepositions and single letter conjunctions as required by Czech and Slovak typographical rules. It is implemented using encTeX and provides files both for plain TeX and LaTeX.
