The databases should be your first stop for reliable, trustworthy, and accurate information. The databases contain full-text articles from magazines, newspapers, and government reports. These are the sources that teachers want to see on your bibliographies.
Books will be extremely valuable to you for this topic. The McCulloch Library has a plethora of books, some of which are highlighted below, on a variety of "homefront" topics: healthcare, women's roles in the war, the press, etc. These books will contain information/primary sources that simply aren't available on the general web.
The ABC CLIO American History database will also be very useful. There are extended features on almost all of the topics for this project that include primary sources, images, and lengthy articles. Under the eras section there is also a link entitlted Civil War Homefront. When doing general web searching (and looking in the indexes of books) remember to use various keyword searches and not just "Civil War Home Front" Try urbanization, industrialization, desertion, Copperheads, Peace Societies, Industrialized North, Civil War Economy, cash crops, Southern Unionists, etc.
