James P. Wind in Places of Worship: Exploring Their History has put together a list of probing questions that will start a researcher on the quest of a true word picture of the congregation.
You may have ready answers to some of the questions, but there are some you likely haven't even thought about. Because each congregation is unique, there are no perfect or complete sets of questions or answers to the questions. They simply provide a route for a researcher to take.
Armed with these comprehensive set of questions, the researcher can now seek places to find answers.
