Comprehensive TeX Archive Network
The CTAN root directory
This is the root of the Comprehensive
TeX Archive Network directory tree.
Most information in CTAN is contained in subdirectories:
Systems for maintaining and presenting bibliographies within documents
typeset using TeX
- Collections of
TeX mailing list digests,
TeX-related electronic magazines, and indexes,
etc., of printed publications
Printer drivers and previewers, etc., for .dvi files
Fonts written in Metafont, and support for using fonts from other
sources (e.g., those in Adobe Type 1 format)
Systems and TeX macros for producing graphics
and similar direct assistance
Systems for maintaining and presenting indexes of documents typeset
Manuals and extended how-to information; errata for
TeX-related publications, collections of project
(e.g., LaTeX and NTS)
ZIP files of ready-to-install CTAN packages. The package contained in
CTAN directory a/b/c/d/ appears as
install/a/b/c/d.tds.zip – each such file may be unzipped
tree, and should contain no “tree prefix”
Support for various languages; hyphenation patterns
macros; several directories have significant sub-trees:
The ConTeXt distribution
and contributed material
- Macros that work in several environments
distribution and contributed material
- Macros that require the LuaTeX engine
- Donald Knuth's example macro set and contributed material
- Macros that require the XƎTeX engine
Material which is now obsolete, but which needs to remain
on the archive for some reason (such as the 1992
distribution). The tree maintains a “shadow hierarchy”
– for example obsolete/macros
has the same basic structures macros.
TeX support environments and the like
organised by operating environment, but also including:
- Donald Knuth's current distribution.
Complete systems that can potentially operate in more than one
- The distribution of MacTeX for Mac OS X
The Live collection of freely distributable TeX
material, including the TeX
Live on-line installer.
The distribution of MiKTeX; CTAN provides a
home for MiKTeX's package repository, part
of its online installer.
The TeX Directory Structure standard
(the output of the TUG TDS working group)
- Information supplied by TeX User Groups
Literate Programming tools and systems
CTAN on the Web
The home page for CTAN is at
which provides several features:
You can search the content of the Catalogue with the
following form on the CTAN site:
In addition, CTAN archives maintain lists of their contents
as plain text files, in a number of ways:
Sorted by name
(This is a big file…around 20M bytes).
New or changed in the last 7 days
(This is usually a more manageable size…)
This is an experimental page. Comments, to
the CTAN team,
will be most welcome.
