Actually there is an automated Erdos number search here:

http://www.ams.org/mathscinet/collaborationDistance.html

using the MathSciNet reference database. Unfortuately, it is only accessible to MathSciNet subscribers, so basically on all university campuses or libraries.

My Erdos number is no higher than 5 :-).

Hm. My old professor has an Erdős number of 3. I should see about authoring a paper with him…
