Appropriateness of a second-authored article in external review file for tenure I am wondering what others thought of including a second-authored article being included in an external reviewer file for tenure review in the health sciences. This is my second tenure review, since I transferred institutions, and my tenure did not transfer from my original institution where I was granted tenure. 

I can include five articles in my external review application. For one of my main areas of research, my collaborator and I provide equal leadership, so we generally switch between first and second authors. The article from our work that I would like to include has me as the second author, not first. Do others believe that it would be strange for a reviewer to see a second-authors publication included in a file?
It sounds reasonable to me, especially if explained as you did above.
