Teachers- how do you find out which schools are hiring?

I recently moved to LI from NYC and dont know how to go about finding out what schools would hire me. In the city I went through the Board of Ed, but is it the same out here?
Do I contact the schools directly?
Thanks!

The new york times has a big help wanted section for eduation positions in the Sunday editions. Good luck!!

Thanks!!
