For those scholars who are serious in their pursuit of primary source data, a historical society is one of the best resources the scholar can access. Historical societies typically house a wide range of primary source material related to a particular state or region. Some are found attached to libraries, while others have their own buildings. The scholar can generally find out basic material about the historical society from their websites, but here is a brief list of items you should have with you when you visit.
Students should also check out the societies website prior to the visit to check on specific policies, what time the society is open to the public, whether cameras are allowed, and eating/drinking rules before proceeding. If you are really diligent you can check to see what resources might be in closed or open stacks.
