typed out a whole email and LOST IT when system crashed! argh! basically, I have a degree in library science but work in records management. I'd say contact a reference librarian as they study this stuff, the art of communication being something that concerns them.
there are 2 types: true homophones, or sounds that actually mean 2 different things, euthanasia/youth in Asia is one; and pseudohomophones, things that are slightly "off" true homophones: grease/Greece turkey/Turkey china/China cold (illness or temp) wales/whales eunuchs/UNIX pseudohomophones oranges and peaches/on the origin of species valueline (business reference)/volume 9 I'd suggest contacting a reference librarian and asking them to point you to an article or material on a listserv.
