During World War I the American Library Association (ALA), through it's War Library Service, provided books and magazines to soldiers and sailors in military hospitals. It placed over 200 libraries in hospitals. In 1920, after the war, ALA's Hospital Library Service was transferred to the U. S. Public Health Service but ALA continued to staff the hospital libraries for a period. Hospital library service was a major legacy of ALA's involvement in World War I. ALA produced a number of postcards to advertise its library service in hospitals. The postcard above shows soldiers reading in the library located in the Red Cross House at Camp Custer, Michigan.
