The Sanford W. Seidler Aircraft Carrier Collection is comprised of textual and visual materials collected and created by Seidler during his radio technician military service and his work as an electronic systems engineer post-war. Dates range from 1943-1991, although the bulk of the material is dated 1969-1974. The collection has been divided into two series based on format and organized alphabetically within the series due to its small size.

Series I, textual materials, is relatively small. The series holds documents related to Seidler's departure from World War II service as a United States Navy Radio Technician, Third Class, including three booklets "Going back to civilian life," "The Last word on life insurance for men discharged from the Navy," and "Handbook of New York State's services and benefits for veterans and their families." Also present is a referral sheet and correspondence from the "District Civil Readjustment Office." Additional materials relate to Seidler's work as an Electronic Systems Engineer for Norden Systems, including a job description, a photocopy of a sales order and contract between Norden Systems and Naval Surface Weapons Center, and correspondence and reports related to the CASEE (Comprehensive aircraft supporrt effectiveness evaluation) simulation program. A welcome packet for the U.S.S. Enterprise is also present.

The bulk and strength of the collection is Series II, photographs and slides. There are 385 color 35mm slides, taken by Seidler during his time on various aircraft carriers from 1969-1974. The USS Enterprise is the most heavily represented in the collection, but activities on the USS America, Forrestal, and Ranger are also depicted. The slides are grouped by carrier when Seidler was posted there to implement and test the CASEE simulation program. Images depict the carriers, both from the exterior and interior; military service personnel engaged in daily duties like maintenance as well as ceremonies and band performances; military aircraft landing, taking off and stationary on the carrier decks, and coastlines as seen from the carriers. There are also nine black-and-white 5x7-inch photographs. One depicts an aircraft carrier, while the rest depict street scenes, likely in post-World War II Japan. Images include boats in a waterway (possibly a floating market), a traffic officer, civilians and scenic shots of buildings. None of the items include captions or contextual information.
