A part of Heritage Quest called PERSI (Periodical Source Index) could be a gold mine for you. Search under People or Places and find a list of articles in genealogical journals. When you find an article that interests you, request a photocopy through the Library's Interlibrary Loan services, usually at no cost. To make a request, go to the Interlibrary Loan request form, log in with your library card and PIN and click on "Make a Request - Photocopy."
