How to present publication output on CV when you publish in fields where author ordering conventions vary? I'm doing research in two different subfields, one of which usually orders names alphabetically and one of which usually orders by contribution. My last name starts with Z, so I'll always be last author in the former field. Both fields are close enough to the divide that it's not clear to an outsider which convention they would use.

How can I point this out in my CV? I can see three options:


Don't do anything, and just be last author on half of the papers.
Write "the author listings in items 2, 4, and 7 are alphabetical", which feels tacky.
Write "the author listings in papers in this subfield are alphabetical", which also feels tacky.


Is there anything else I could do? Should I be worrying about this at all?
I would suggest adding a remark like the following to your list of publications in your CV.


  I publish in multiple fields, with different standards for ordering authors, some ordering by contribution and others ordering alphabetically.  In the list below, first authors are indicated in bold when authors are ordered by contribution; the symbol = indicates a paper with alphabetically-ordered authors.
