I work at the Post Street Archives in Midland, MI; and I wanted to be a part of discussions in the Wikipedia community, and expand the information available in Wikipedia, as relates to items and subjects in our collections.
In the interest of full disclosure, the Post Street Archives is a division of the Herbert H. and Grace A. Dow Foundation, and the mission of the Post Street Archives includes providing historical analysis; using the materials in our care to provide educational and cultural opportunities to the community where we are located; and to serve the needs of scholars, writers, historians, and the general public within an archival environment.
Update: As of 9-26-08, I will no longer be active at this account. It has been a pleasure to be a part of the Wikipedia community.
