A review of military operations in the Pacific provides context for appreciating the origin, arrangement, and condition of the records. The Philippine Archives Collection, created to document military operations and individual participation in the war, is a valuable source of information about the war and about the people who engaged in wartime activities.

After several reorganizations and transfers of the RPD's records, the new Adjutant General Records Depository (AGRD) of the Adjutant General’s Section acquired the Records Division of the Claims Service and the “Project J” and Philippine Army branches of RPD (the records that would become the Philippine Archives Collection). Another new unit, the Adjustment Section of the Headquarters office of the Philippine Command became responsible for adjustment of claims and arrears in pay.
Many records related to recognized guerilla units and Philippine Army personnel are transferred to St. Louis, Missouri, in custody of the Demobilized Personnel Records Branch (DPRB) of the Adjutant General's Office.

Records related to intelligence activities and created by the USAFFE G-2 (Intelligence) office, are maintained by the Office of Special Investigations (OSI) in two places: at Clark Air Base in the Philippines and in Japan. (OSI returns the records to AGRD in the late 1950s.)

|1994||The National Archives moves the Philippine Archives Collection to its new facility in College Park, Maryland.|
Some records in the collection predate the invasion period by almost a decade, while other records date nearly 30 years into the postwar era. The collection spans 48 years – 1930-1978. This date span, however, should not be interpreted to mean that the collection holds significant records of the pre-invasion and postwar periods; the primary focus of the collection are the experiences of men and women who participated in the action on the Philippine Islands from the time of the Japanese invasion in December 1941 to the end of World War II.
