----------------------------Original message---------------------------- Cheryl, I don't know if this will prove to be of any help but a colleague (and past coworker) of mine works for the National AIDS Clearinghouse at the Centers for Disease Control in Atlanta. She may be able to provide other map citations besides those mentioned by Ross and Ellie. Contact: Ms. Jeanne LaRocco CDC National AIDS Clearinghouse Research Center 18 Executive Park Suite 1804 Atlanta, GA 30329 Phone: 404-982-0353 Email: [log in to unmask] Tell her Paige sent you to her. If she doesn't have anything cartographic in nature in her collection I'm sure she would love to here about those citations Ross and Ellie provided on MAPS-L. Hope this helps! Paige
