I typed "hemoglobin C" in the ProQuest Medical Library search box and got several results. The quotation marks ensure that the results are limited to hemoglobin C and not other kinds of hemoglobin. The database Oxford Reference Online provides a basic definition. I also suggest the Academic Search Complete and Medline databases. If you are not on campus at City Park, you will be asked to provide a username and password for all databases. User your LOLA# for the username and your birthdate formatted mmddyy for the password.
Outside of databases, St. Judes Childrens' Research Hospital, a trusted research facility, has some great background information. The government site PubMed Health also has some good information about Hemoglobin C disease. Medlineplus.gov is also a good website.
