the_author archived?

I had a question about the_author_whatever tags. I’m currently writing a custom theme for a non-profit organization (this is pro-bono work). They have board positions which remain the same every year – but the people who are *in* these positions change every year. I want to create these positions in the WordPress theme, and when new board members are elected into old positions (offices are taken every September), they are just issued the same login with a new password. So, for example, if Mary Smith is President this year, but Jamie Jones is elected as President next year, the user of “President” remains constant – just Jamie gets a new password so she can log into the system as such.

What I want to know is, is there a way I can *archive* the past positions’ author info? I’m using the_author() tags to display author info for these posts they’re making, but September 2006’s President is different than September 2007’s, and I’d like the archived area to retain the old info with the old posts (so when you pull up an archive from 3 years ago, it doesn’t display the author info from the current year, but the author info from 3 years ago).

Interestingly enough, I just remembered that these particular posts will *all* have custom meta information as well. Perhaps I could work that in there to provide my archive? Just wondering if anyone has any ideas for me. Thanks!
