Each year, the J. Welles Henderson Archives and Library answers hundreds of reference inquiries, in person, by phone and by mail with inquiries coming from all over the world. Researchers have asked for images of the ship on which an ancestor first came to America, for information about medical practices in the early U. S. Navy, for copies of plans to build a small craft, and if the nearby Moshulu is the same ship that appears in the movie The Godfather: Part II. (It is.)
Genealogists should be aware that the J. Welles Henderson Archives and Library collections generally do not support detailed genealogical research. Those beginning to undertake a genealogy project are strongly encouraged to view the National Archives Genealogy Page before contacting us.

The J. Welles Henderson Archives and Library is open to the public by appointment only, Monday through Friday, from 10 a.m. to 4:00 p.m. As with most special collections libraries, because the collections necessitate particular handling and staff time is limited, an advance appointment is required for admittance. J. Welles Henderson Archives and Library visitors must purchase a museum admission ticket or have a current museum membership - tickets and memberships may be purchased at the Visitor Services desk upon arrival at the museum.
