You can hyperlink DOI numbers to doi.org. However, some publishers have elected to use nasty characters in their DOI numbering scheme (<, >, _ and ; have all been spotted). This will either upset LaTeX, or your PDF reader. This package contains a single user-level command \doi, which takes a DOI number, and creates a correct hyperlink to the target of the DOI.

DSSerif is a mathematical font package with double struck serifed digits, upper and lower case letters, in regular and bold weights. The design was inspired by the STIX double struck fonts, which are sans serif, but starting from a Courier-like base.

This package recreates some AmongUs characters in TikZ environments. Some interesting uses alongside other packages are also supported.

This package provides bold latin and greek characters within \mathversion{normal}, by using ~ and " as prefix characters.

This PSTricks package facilitates the drawing of protractors, rulers, compasses and pencils.

The 2up package offers considerable flexibility as to paper size and layout, and produces a standard DVI file without involving additional DVI or PostScript filters.

The package is prepared for typesetting some German translations of the Holy Quran. It adds three more German translations to the quran package.

This package provides a tool (preprocessor) for writing your pRaa-ne-r ka-thaa in the Bengali language. It allows one to write the text in Rapid Roman Bangla and convert it to the BangTeX format by a Python program. All LaTeX markups are preserved in the target file.

The distribution includes a package and a Lua library that can together read OpenDocument spreadsheet documents as LaTeX tables. Cells in the tables may be processed by LaTeX macros, so that, for example, the package may be used for drawing some plots. The package uses Lua's zip library.

This LaTeX package allows the creation of (even large) Karnaugh maps. It provides a tabular-like input syntax and support for drawing bundles (implicants) around adjacent values.

The package provides the \pdfmarginpar command which is similar in spirit to \marginpar. However, it creates PDF annotations which may be viewed with Adobe Reader in place of marginal texts. Small icons indicate the in-text position where the message originates, popups provide the messages themselves. Thus bugfixes and other such communications are clearly visible together when viewing the document, while the document itself is not obscured.

This is a Greek font written in Metafont, with inspiration from the Bodoni typefaces in old books. It is stylistically a little more exotic than the standard textbook Greek fonts, particularly in glyphs like the lowercase rho and kappa. It aims for a rather calligraphic feel, but seems to blend well with Computer Modern. There is a ligature scheme which automatically inserts the breathings required for ancient texts, making the input text more readable than in some schemes.

The Perl script pkfix looks for DVIPSBitmapFont comments in PostScript files, generated by not too old dvips, and replaces them by type 1 versions of the fonts, if possible.

E-TeX provides 32 768 mark registers; using this facility is far more comfortable than LaTeX tricks with \markright, \markboth, \leftmark and \rightmark. The package provides two commands for marking: \marksthe and \marksthecs, which have starred forms which disable expansion; new mark registers are allocated as needed. Syntax is closely modelled on the \marks primitive. Four commands are provided for retrieving the marks registers content: \thefirstmarks, \thebotmarks, \thetopmarks and \getthemarks; and the command \ifmarksequal is available for comparing the content of marks registers. The package requires an e-TeX enabled engine, and the etex package.

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.

nomentbl typeset nomenclatures in a longtable instead of the makeindex style of nomencl. A nomenclature entry may have three arguments: the symbol, description and physical unit.

The package provides a paragraph generator designed for use in Plain TeX documents. The paragraphs generated contain many f-groups (ff, fl etc.) so the text can act as a test of the ligatures of the font in use.

This package provides environments for selectively including or excluding pieces of text, allowing the user to define new, separately controlled comment versions.

The package provides a version of the LaTeX for Word Processor Users document in Italian.

This package provides LaTeX, pdfLaTeX, XeLaTeX and LuaLaTeX support for the Inter Sans family of fonts, designed by Rasmus Andersson. Inter is a typeface specially designed for user interfaces with focus on high legibility of small-to-medium sized text on computer screens. The family features a tall x-height to aid in readability of mixed-case and lower-case text.

This package provides a complete set of macros for information, warning and error messages. Under LaTeX, the commands are wrappers for the corresponding LaTeX commands; under Plain TeX they are available as complete implementations.

This package provides an extended version of the Japanese document class collection provided by jsclasses. While the original version supports only pLaTeX and upLaTeX, the extended version also supports pdfLaTeX, XeLaTeX and LuaLaTeX, with the aid of suitable packages that provide capability of Japanese typesetting.

This package adjusts the figure and table environments to ensure that centered objects as one line captions are centered as well. Also the vertical spaces for table captions above the table are changed.

This package provides a means of writing vanilla letters and memos is provided, with support covering ConTeXt Mkii and Mkiv. The design of letters may be amended by a wide range of style specifications.
