those researching from a distance, there is an inter-library loan
service for microfilm. However, you may wish to contact the Archives to
determine whether the documents you are requesting are available on
microfilm, and if so, whether they are subject to any access
restrictions due to privacy considerations.
The other alternative, of course, is to hire a local researcher to do more in-depth research for you.
