What to Expect When You Visit the Archives
You’ll have the help of one of our many knowledgeable volunteers to help you search through our collections and help you find what you’re looking for. However, it is most helpful for our staff and volunteers if you know what you’re looking for when you visit us. Knowing the names you’re looking for and the types of records would be great! But if you don’t know exactly what you’re looking for, that’s okay! We’re here to help you find all that we have.
