Article with unspecified-but-present authorship ("consensus document") I'd like to properly refrence an article whose author is mentioned as A Consensus Document (it has some 25 authors).

I have never seen this kind of authorship before; the citation entry generated by the website does not contain an "Author" field (which is problematic for BibTeX and somewhat intriguing on a personal level).

I don't know what would be appropriate to remedy this situation. Would adding an author such as Consensus Document make sense?

Otherwise, could I just add the first author in alphabetical order1, or would this misrepresent the authorship?

Another possible alternative is that, since one of the authors (not the first one in alphabetical order) wrote a foreword to the paper, maybe he could be considered as the first author instead?

1 The authors are only presented in alphabetical order.
The website you've linked to, under the "How to cite" tab, suggests the following format for the entry:


  (2008), Vacuum Assisted Closure: Recommendations for Use. International Wound Journal, 5: iii–19. doi: 10.1111/j.1742-481X.2008.00537.x


Note that there's no author information at all. I suppose that's not a problem for numeric-style citation call-outs, but it sort of begs the question what should be done if authoryear-style citation call-outs are to be used.

The printed article itself provides the string "Expert Working Group" (followed by the names of all members of the group) where one would usually provide the authors' names. This suggests using a "corporate author" approach, along the following scheme:

@article{vacrfu:2008,
  author  = {{Expert Working Group}},
  title   = {Vacuum Assisted Closure: {Recommendations} for Use},
  journal = {International Wound Journal},
  year    = 2008,
  volume  = 5,
  pages   = {iii--19},
  doi     = {10.1111/j.1742-481X.2008.00537.x},
}


Note the use of double curly braces around the argument of the author field.

If that's too unconventional for your taste, you might try either 

  author  = {{Expert Working Group (Apelqvist et al)}},


or, more simply, 

  author = {Jan Apelqvist and others},


as the content of the author field.
