A librarian from San Diego, Clara Breed, made a point of maintaining contact with Poston camp children she had met in San Diego. She corresponded with many of them and sent them reading materials and other gifts. Their letters to her became an important record of life in the camps. Hundreds of "Dear Miss Breed" postcards and letters are now part of the permanent archives at the Japanese American National Museum and were the basis for a 2006 book, "Dear Miss Breed: True Stories of the Japanese American Incarceration during World War II and a Librarian Who Made a Difference," by Joanne Oppenheim.
