Need help gathering government agency bond data for a fixed income class...

[ProvingGround]

I'm looking for historical yields for both Export/Import banks as well as for GNMA.

I can't acess our Bloomberg terminal until Monday and I have googled and searched through all our library databases.

I'd appreciate it if someone could point me in the right direction.

Specfically am looking at post recession years 1982, 1992, 2002, 2009.

Thanks.
