Below are some resources you can use to look for jobs in academia as well as outside of the academy. This is not an exhaustive list, but it is a good place to start thinking about what you want to do with your degree.
Academic Job Listings
American Historical Association's Perspectives http://www.historians.org/perspectives The job ads published in Perspectives can only be accessed by members, but the publication has great articles on the job market and the historical profession that can be accessed by non-members.
H-Net Job Guide http://www.h-net.org/jobs H-Net is a resource available free of charge to all, searchable by major geographic fields as well as by posting dates. Most history jobs published elsewhere are also published on H-Net.
