Answer:

answer: 

After scouring search engines, I was unable to find a list of Hartman's lectures and radio talks. Even her personal website linked from Columbia University's site no longer works.

However, I did find contact information for Hartman, which might be your best bet for acquiring a complete list: http://www.columbia.edu/cu/english/fac_profiles.htm#svh2102

I hope this helps.
