n the early 1950s the Archive of Folk Song of the Library of Congress was afforded the opportunity of acquiring an extensive collection of American Indian music recorded in the field between 1940 and 1952 by Professor Willard Rhodes. Most of Dr. Rhodes' collection had been done under the auspices of the Education Branch of the Bureau of Indian Affairs, U.S. Department of the Interior, with additional funding from the Library of Congress on his final expedition. Through a desire to preserve these valuable recordings and to make a portion of them available to Indian schools, agencies, and students, the Bureau transferred to the Library enough funds to cover the manufacture of ten long-playing recordings, to be selected and edited by Rhodes from his overall collection. The collection itself covers fourteen states, and includes the music of fifty Indian tribes. Rhodes employed the most modern portable disc and tape equipment available to him at the time, recording a total of 260 10 and 12 discs during the summers of 1940, 1941, 1942, 1943, 1947, and 1949, and fifty 7 tape reels in 1950, 1951, and 1952. Copies of these discs and tapes, as well as many of the originals, are now housed in the permanent collections of the Archive of Folk Song, along with content lists supplied by Rhodes. The following is a summary of the areas and tribes represented by the nine expeditions made by Rhodes:
