The correct zip for Mattoon, Illinois is 61938. Sorry! Guess nobody from Nov. 2001 until now read the message and followed up on it. NOTE! There are zip code changes taking place in June 2004 for Springfield, IL. (I think they start today, June 26). SOOO, before writing to Springfield, check to see if the zip for the Illinois State Genealogical Society has changed. You might also want to check to see if MaryLea Degler is still the Prairie Pioneer chairperson.
