As vice governor of the Philippine Islands during the 1930s, and later as advisor on Philippine affairs to General Douglas MacArthur during World War II, Joseph R. Hayden was recipient of much substantive documentation relating to the American phase of Philippine Island history. Hayden was an astute and discerning scholar of Philippine life and history, and as such used the opportunity of his frequent trips to the Far East to collect materials (official and personal) that he knew would be of value in his teaching and research, and that he also hoped would prove useful to scholars following after him. The Philippine Collection is the heart of the collection comprising more than 75% of the Hayden papers. These files are testimony to Hayden's foresight in drawing together official documents (because of the positions he held) and other records (sent to him because of his known interest in the Philippines). These collected materials include official reports, minutes of meetings attended, memoranda with government officials, photographs, clippings, and published materials.
Over the years, researchers, unable to examine the originals, have requested microfilm copies of portions of the Hayden papers. This finding aid lists those files that have been microfilmed and which are available for inter-library loan. The bulk of these files date from the 1920s and relate in great part to the Philippine politics and to the affairs of the provinces. Many of the files relate to the Moros and to Mindanao and Sulu. The finding aid to the original collection is also available through the library's homepage.
