Hey, got some­thing new for CTAN? Great! This page al­lows you to up­load it.


Ready? Then fill in the fields be­low and up­load.

  1. Please add a few bits of in­for­ma­tion that will help us to cat­e­go­rize it. The re­quired fields are: your name, your email, and a sum­mary (which is typ­i­cally just a few words, or at most a sen­tence).

    • In ad­di­tion, your sug­gest­ing a CTAN di­rec­tory is a help (if you are not sure, just leave it blank). And, a one or two para­graph de­scrip­tion will, be­sides be­ing in the an­nounce­ment made when the pack­age is in­stalled, be the ba­sis for what might go into the Cat­a­logue. You can help to bring your work to the largest au­di­ence by mak­ing sure that this de­scrip­tion is clear to a non-ex­pert and that it in­cludes words that a per­son might use in a Cat­a­logue search.
    • About the an­nounce­ments: we have a mail­ing list for peo­ple who are in­ter­ested in hear­ing about changes in our hold­ings. New pack­ages are al­ways an­nounced on this list. For a re­vi­sion of an ex­ist­ing pack­age, please note that we don't mail the list about re­vi­sions that are bug fixes, mi­nor fea­ture ad­di­tions, etc. If you make a ma­jor up­grade and would like an an­nounce­ment then tell us so, and in­clude a de­scrip­tion of the im­prove­ments.

  2. Indi­cate the li­cense. We need to know the li­cense un­der which you are shar­ing your work. For more in­for­ma­tion about the dif­fer­ent kinds, see the Cat­a­logue Li­cense Def­i­ni­tions. If you don't know what to pick, you might note that the LaTeX Project Public Li­cense was de­vel­oped to suit this pur­pose.

    Please also in­di­cate the li­cense within the pack­age it­self, at least in the top-level README .

    Note that some file names are blocked, like those end­ing in .exe , .php , .asp , .cgi . We would pre­fer a sin­gle zip archive. Please do not use any spe­cial or non-print­able char­ac­ters (like blank spaces) in file names.

  4. Thanks for pro­vid­ing the in­for­ma­tion – and thanks for your con­tri­bu­tion. You keep TeX go­ing!



To get ready for up­load­ing please read the points be­low. You may also find help­ful the in­for­ma­tion at­con­trib.html.

  • If you have more than one file then please pack­age your con­tri­bu­tion as a ZIP archive or a gzip-ed tar archive (with the ex­ten­sion tar.gz or tgz).

    The CTAN team has de­cided that pack­ages on the archive shall re­main in a brows­ing-friendly lay­out, i.e. the best for­mat is to have all the files in­side a di­rec­tory, as il­lus­trated here.

    Here xxx should be the CTAN name of your pack­age.

  • Very large pack­ages (such as mod­ern font dis­tri­bu­tions) are im­proved by a sin­gle ex­tra layer of di­rec­tory:

    and so on.

  • In par­al­lel to the main di­rec­tory tree, CTAN of­fers the in­stall/ sub­tree for TDS-struc­tured ZIP files. Such a file will only be ac­cepted as an ad­di­tion to your up­load, not as a re­place­ment. If you want to in­clude such a file in your up­load, please check the TDS guide­lines. Call this file and in­clude it at the toplevel of your up­load (along­side the xxx di­rec­tory).
  • Even if what you are send­ing is a re­vi­sion of an ex­ist­ing pack­age, please send all of the files, changed or not. We have tools to han­dle whole up­loads so this leads to the fewest er­rors on our part.

  • We hold thou­sands of pack­ages, and many thou­sand files. Our vis­i­tors will be helped, and your work will get the recog­ni­tion that it de­serves, only if peo­ple can find your pack­age.

    • In­clude in your up­load a plain text file with in­for­ma­tion that would be use­ful to a CTAN vis­i­tor con­sid­er­ing us­ing your pack­age. This in­for­ma­tion in­cludes a brief de­scrip­tion and li­cense in­for­ma­tion, as well as whether your ma­te­rial re­quires spe­cial fonts or only runs on one kind of plat­form. Name this file README be­cause then it will show up at most sites when that user is brows­ing your di­rec­tory.

      In­clude in the README file a state­ment giv­ing your choice of li­cense. That way peo­ple who are brows­ing can see whether your ma­te­rial is avail­able to them (e.g., if your li­cense choice ex­cludes com­mer­cial use). Some­thing like: This ma­te­rial is sub­ject to the LaTeX Project Public Li­cense.

    • Al­most all pack­ages should have doc­u­men­ta­tion be­yond the README. It should be in PDF for­mat, since this is what our web vis­i­tors can read; in par­tic­u­lar, Postscript and DVI for­mats are not ac­cept­able. In­clude its source in your up­load since free dis­tri­bu­tions such as TeX Live can­not use the doc­u­ment with­out source. (For many LaTeX pack­age au­thors, pro­duc­ing the doc­u­men­ta­tion is a mat­ter of run­ning your .dtx file through pdfLaTeX: pdflatex <docname>.dtx.)

Some ad­di­tional prac­ti­cal tips can be found in the Ad­di­tional In­for­ma­tion for CTAN Upload­ers.
