In my work I have to cite some papers from the Planck Collaboration. Unfortunately, in my bib file, it is always placed as the first author:

author = {{Planck Collaboration} and Akrami, Y. and Arroja, F. and Ashdown, M.} %and so on

When I call the reference with, for example


I obtain "Planck Collaboration et al (2018)", while I would like to obtain "Planck Collaboration (2018)". I want this change only for certain references, and I was wondering if there is some option I can give to Textcite (or equivalent) to not place the "et al" here. I could only think about manually writing

Planck Collaboration (\cite*{planck2018})

But I know this is style dependent and could give some problems if I have to change the style

I am using biblatex with the biber backend.

Note: this question is similar to Remove "et al" from one in-line citation (unaswered), but using biblatex and biber, which may give more flexibility.

    Please help us help you and add a minimal working example with bibliography (MWEB) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. Aug 15, 2018 at 12:05

    Normally you can't suppress the "et al." it is generated automatically and if it was suppressed in the output that could lead to confusing name clashes. I would suggest shortauthor = {{Planck Collaboration}}

  • @moewe That worked perfectly, I did not know about that field (I guess I was too focused searching for collaboration in the docs haha). If you turn this into an answer I will accept it so future people find it easier.

    If I understand correctly, the Planck Collaboration in this instance is exactly those hundred-something people listed in the paper, so author = {{Planck Collaboration} and Y. Akrami and ...} is not strictly speaking correct. It's either author = {{Planck Collaboration}} or author = {Y. Akrami and ...}. biblatex and BibTeX have no notion of "a group consisting of ..." - you can either list the group name, or each member individually.

    Yes, that is exactly the case. My bibliography comes from a standard source in Astrophysics, NASA ADS (adsabs.harvard.edu/cgi-bin/bib_query?arXiv:1807.06208 ), where it lists it as an additional author.

If I understand correctly, the Planck Collaboration in this instance is exactly those hundred-something people listed in the paper, so

author = {{Planck Collaboration} and Y. Akrami and ...}

is not strictly speaking correct. It would be either

author = {{Planck Collaboration}}


author = {Y. Akrami and ...}

I can see how each of those solutions is not perfect: If you give only the group name, you effectively deny the people their name in the citation (although you would not give all hundred odd names anyway, so only about three out of 120 people will be mad at you, that is quite a good overall score). But if you cite only the people, the collaboration name, which is probably more widely known, will not be mentioned.

Unfortunately, biblatex and BibTeX have no notion of "a group consisting of ..." - you can either list the group name, or each member individually.

In this case you might be able to get away with

shortauthor = {{Planck Collaboration}}

but note that while the citation will look as expected, the bibliography entry will still have an incorrect "and" or "et al." if you use author = {{Planck Collaboration} and Y. Akrami and ...}.

I guess it would be ideal if you could put all individual names into the author field and the collaboration name into shortauthor. You would then have to convince your bibliography style to show both the shortauthor (collaboration name) and author (individual names) in the bibliography. Off the top of my head I know of no style that does this by default, but the modifications necessary to make biblatex do this are not too involved.


\usepackage[style=authoryear, backend=biber]{biblatex}

    test \ifuseauthor
    not test {\ifnameundef{author}}

  shortauthor = {{Planck Collaboration}},
  author      = {Y. Akrami and F. Arroja and M. Ashdown and J. Aumont and C. Baccigalupi and M. Ballardini and A. J. Banday and R. B. Barreiro and N. Bartolo and S. Basak and K. Benabed and J.-P.

  • Thank you, you are completely right. If I set author = {{Planck Collaboration}}, is there a field to still have the complete list of authors in the .bib file, in case I would like to name them eventually?

    @Javier Not really, no. You could put them into the editor or any other name field, but that would not feel right and would not give good output. You could use the nameaddon field, which is not used by the standard styles, but then you would not see the names in the bibliography ...

  • Thank you for your answer and the edit, I think that modification to show the shortauthor in the bibliography is probably the best way to go for me.

  • @Javier I agree that that is conceptually the nicest solution, but it is not very portable, I'm afraid.
