The "Encyclopedia Arctica" papers contain manuscripts, correspondence, bibliographies and indexes of reference works related to northern arctic and subarctic regions. Four sets of the manuscript were in existence in 1954; three under the care of the Navy and one in the Stefansson Collection. In 1970, a microfilm was produced and is available for consultation; however, the manuscript in the Stefansson Collection includes additional material -- never filmed. A 12-volume set, bound in blue cloth, is also held in the Stefansson Collection.
