Yes, you will be responsible for any elections that are held in 2010. (The 'election reform' bill that passed in last year's legislative session won't take effect until January, 2010.) At the election, which will be held on May 25, 2010, you will elect a trustee who will serve until 2015. (You might have to elect a trustee to fill out a term they were appointed to as well.)

According to Idaho code 34-1405(2), you need to notify your county clerk about your trustee election by the last day of November. (Many county clerks send out a reminder, but don't let it catch you by surprise!)

ICFL won't be mailing out an election calendar this year, but it can be found under 2010 District Library Trustee Election Calendar

I will send out reminders to both LibIdaho and post on this blog as the time gets nearer, but for now, keep March 5 - 12 in mind as the first date(s) you need to be aware of (publish notice of petition availability and filing deadline.)
