I was able to find an obituary for Catholic Charities from the 1974 Chicago Tribune quickly by using the Historical Chicago Tribune database on the College of DuPage website. The address is www.cod.edu. Click on the library link. Use my COD library card number to get into the database.
I found the obit on a PDF page which was not very clear, so I did then go to our microfilm which was to make a copy for faxing.
