The Papers of Edward Pearce and Lily Anderson Hayes are comprised of correspondence, journal entries, informational files, photographs, speeches, newspapers in both English and Chinese, and conference programs and journals, dating from 1916 to 1988. This collection reflects the Hayes’ passion in their mission work in China, as well as Edward Pearce Hayes' view on Communism and its perceived threat to the United States.

The largest part of the collection is correspondence. Edward Pearce Hayes signs his name as Pearce in his letters. The bulk of the correspondence (1938-1947) is letters from Edward Pearce Hayes in China to his wife and family residing in the United States. These letters recount his life in China. The letters discuss homesickness and difficulties due to lack of money, food, and clothing. They also allow for a glimpse into the uncertainty of life during war time, including rumors about the path of war, bombings, and government unrest. Once Lily rejoined him in China for the one hundredth anniversary of Methodism in China, they both sent letters to their family in the United States. These letters (1947-1950) inform family about daily life and how it had changed before, during, and after the communist takeover in China, which later produced the People’s Republic of China. These letters also discuss the ever changing prices in China, rumors about the happenings in cities and towns taken over by the Communists, information on the fate of other missionaries, reasons for staying in China longer, and the evacuation of other missionaries.

Another collection of correspondences pertain to Edward Pearce Hayes’ 1958 and 1961 trips for the then Methodist Church Board of Missions in New York. These letters, written to his wife, discuss his daily life, as well as give a glimpse into his thoughts on issues in Asia, Africa, and Berlin, as well as his thoughts on the state of the Methodist Church and mission issues.

The collection also includes Edward Pearce Hayes' letters and travel logs about his two trips abroad. In 1952, he traveled to South East Asia. This trip consisted of visiting Japan, Okinawa, Taiwan, Hong Kong, and Manila. In 1955, he traveled to other areas of South East Asia, India, and Malaysia. Both sets of letters and travel logs tell of his daily travels and encounters.

In addition to correspondence, the collection includes files containing biographical information written by the family about the lives of Edward Pearce and Lily. These files also include letters Edward Pearce wrote to friends and family over the years prior to 1938. There are also clippings of Edward Pearce's various speaking engagements, as well as numerous obituaries for both and a clipping about their Golden Anniversary. Other items of note found in the collection are notes written by Edward Pearce for his speeches, and some diary and journal entries from his trips abroad. There are also pamphlets and booklets from Methodist conferences Hayes attended, including a photograph of the 1947 Centennial Celebration of the Methodist Church taken at the China Central Conference, as well as four banners given to the Hayes' as parting gifts upon their departure from China in January 1950. There is a General Conference badge Edward Pearce received when attending the 1940 General Conference in Atlantic City, New Jersey. Another item of note is a 1947 Chinese newspaper printed in Foochow, China, pertaining to the one hundredth anniversary of Methodism in China.

While this collection is primarily in English, there are a few items that are in Chinese. The banners are in Chinese, with translations included. There is a document with his name written in Chinese. This includes a YMCA membership certificate from Foochow. The 1947 newspaper pertaining to the one hundredth anniversary of Methodism in China is printed in Chinese as well.

This collection of personal papers of Mildred Anne Paine includes 23 diaries and journals, photographic images, correspondence, clippings, and biographical miscellany, most of which concern her years of missionary work. The correspondence includes personal, business, and Dear Friends letters.

Most of the diaries contain additional related information tucked between the pages, including letters, poems, prayers and newspaper clippings. The completeness of entries varies from year to year, with the most detailed and personal information from 1957-1974. Some years are missing from this collection, particularly in the period of 1926-1943. The entries are generally written in reflection of the day at hand, noting activities both personal and missionary related, daily concerns and observations, and interactions with colleagues, staff, family, and friends.

This collection also contains genealogical information, including a hand-inscribed book of births, deaths, and marriages dating from 1830, created by Paine’s Aunt, Rena W. Goldsmith. Additionally, Paine kept a birthday book of friends and family dating from 1914.
