How can I find a literary agent who handles plays?

[Peregrine Took]

I'm an unpublished playwright and have been sending my plays all around the country for over a year with no success.

Mostly the theaters don't respond at all. I feel having an agent would help open doors for me as many theaters will no longer accept work from individual playwrights - only agents.

Its very discouraging as my plays are very funny, dark political works and, as a result, are extremely timely.

One serious one, a play within a play, is set during the Viet Nam war.

The others are satirical skewering of modern politics and politicians.

Thanks for any help.
