The deadline for voting in the 2009 SAA election is April 11 at 11:59 PM Eastern Time, which means that anyone who hasn't voted has, at the time of this writing, approximately 55 hours to do so!
If you were an individual or student SAA member of good standing as of 28 February of this year or were the primary contact of an institutional member in good standing as of 28 February, you're eligible to vote in this election.
The online ballot can be accessed here (use your SAA user ID and password to log in), and the candidates' statements are available here.
Trying to make up your mind? To the best of my knowledge, Kate at ArchivesNext is the only person who has posted detailed endorsements online. Some of my choices differ from hers, but, as usual, she clearly outlines the reasons for her choices. If you're on the fence, you might want to see what she has to say.
