Trimming my CV; or, what is appropriate to have in a CV at a given career stage I've been more or less adding material to my CV since I started it while in grad school.  As I am now a much more senior person, I am starting to feel it is a bit cluttered and perhaps larded up with inane facts about my (academic) life.  For instance does it really make sense to continue to include a prize I won as an undergraduate fifteen years ago?  Did it ever?

I'm curious what people think is an appropriate amount of information to include at each career stage: PhD student, Post-doc, Tenure-track, Tenured or if it doesn't make a difference.

I'm in math if people think the subject area matters.
As has been suggested above, keep one version of your CV which is complete with everything you've ever done, and then trim it down as needed for a particular purpose.  I keep my CV up-to-date with lists of publications, conference presentations, grants, courses taught, graduate students supervised, committees served on, etc.  It's a very long document, but its easy to cut/paste what I need in various situations.
