The National Park Service (NPS) [recently launched] a public website: pubs.etic.nps.gov that is making more than 32,000 NPS records available to the public.
For example, the collection contains such important documents as the original drawings of the main immigration building at Ellis Island National Monument, a concessionaire shop in 1933 at Muir Woods National Monument, and historical documents of Alcatraz Island.
The Technical Information Center (TIC) at the NPS Denver Service Center (DSC) is the oldest and largest information system in the National Park Service. TIC is the central repository for proper retention, access, and disposition of NPS records that include drawings, specifications, scientific, and technical reports.
