A much overlooked portion of the New Jersey Archives are their "Imaged Collections."
Over 3,000 images from the Archives photograph and manuscript collection are available free online.
The topics include:
-Portraits of Soldiers -- Civil War & Spanish American War, mostly officers
-Historic Structures, Sites and Parks New Jersey -Institutions Transportation and Public Works
-Military Activities & Monuments
-Military Service Records Governors' Documents
-Cleveland Family Papers
Trust me, this collection is amazing and gives you insight into New Jersey's history and people.
Most of these individual topics are indexed, but unfortunately there is no search engine provided to search them all at once.
