The catalogue began life in 1986! It was originially maintained as a BibTeX database, and started generating HTML in 1992. It migrated to XML using XSL style sheets to generate the various formatted versions of the catalogue in 1997. The source migrated to the open source server Sarovar in 2004, together with a rewrite of all the processing code from XSL to Python, with much relief. The DTD for the Catalogue is in catalogue.dtd or generically here.

The catalogue is regularly updated and others are welcome to join the team maintaining the catalogue. There are bound to be errors in the catalogue. If you come across any, or have comments, enhancements, and additions, please send them to

The catalogue has evolved over quite a few years. Thanks to many who have contributed entries and ideas. In particular, Piet van Oostrum supplied quite a few one line descriptions and Sebastian Rahtz has added many entries for the TUG TeX Live CDROM. Robin Fairbairns and Barbara Beeton have provided various updates and suggestions. Stanislaw Wawrykiewicz maintains many of the Polish entries from GUST. Randy Kobes contributed code and ideas for the alphabetic and hierachical editions and created the extremely useful CGI script used to locate a nearby CTAN node. Jim Hefferon implemented and maintains the Catalogue search facility. Joao Palhoto Matos made the icons look great.

Juergen Fenn maintains the topical index to the Catalogue and Martin Bayer has provided a template for the improved look and feel of the catalogue.

Robin Fairbairns and the CTAN team have been active maintainers of the Catalogue, particularly as new packages are added to CTAN and other deficiencies of the Catalogue are identified.
