The contents of the International Cyclopedia of Aviation Biography (I.C.A.B.) document prominent early aviation pioneers and aviation industries. The documentation was collected by William L. Hamberger of Beacon, New York during the late 1920s and early 1930s in preparation to publish the International Cyclopedia of Aviation Biography. Some files are more extensive than others, depending on the response from the contact person or corporation of interest. The files may contain correspondence, questionnaires, clippings, proofs of entries, and pamphlets or books.

Series I: Individual Files, 1910-1938, consists of 33 Hollinger boxes which contain files on individual men and women who were pioneers in the field of aviation. Items included are newspaper clippings, biographical information, correspondence, photographs and other related materials.
