I am using bibtex with the 'amsalpha' style. I am citing a paper with many authors, and bibtex currently labels this entry as [ABC+04]. But I'd really prefer having all the authors there, as in [ABCDE04]. What is the most efficient way of doing this? I'd hope there's some sort of 'max authors' parameter I can just increase. I am open to using a different bibtex style if necessary. As a last resort, is there a way to simply tell bibtex what label I want for this particular entry (other than changing the .bbl file manually)?

My first answer assumes you want to continue with amsalpha. If so, download the amscls.tds.zip from CTAN, extract it and look for the amsalpha.bst file. Copy a version into the top directory of your document to compile and rename the bst, for example into amsalpha-a.bst.

Code line's #1039 entry "numnames" defines how many capitals are print as label in the text, the next code line #1040 "namesleft" how many capitals are the maximum in the bibliography. Increase these integers -- obviously towards the same integer, and save these two changes. Of course, do not forget to invoke \bibliographystyle{amsalpha-a} instead of the system-wide accessible \bibliographystyle{amsalpha}.

My second answer to this -- if you don't mind to change for a numerical style of bibliography -- is to change for package like achemso. This package provides an option "maxauthors" an easier (and cleaner) way to define the maximum number of authors for one bibliographic reference print.

  • I did this, but now I get something like [ABCDE+04], which is strange since ABCDE are all of the authors. What does the plus mean? (and how can I get rid of it?) – John Pardon Sep 29 '15 at 16:37
  • OK, I modified line #1060 as well and now everything works. – John Pardon Sep 29 '15 at 16:49
