Book excerpt: This highly selective bibliography supplements the original bibliography developed in 1978 by Ms. Betsy C. Kysely, to support the Eighth Military History Symposium While this bibliography focuses primarily on materials published since the earlier bibliography was developed, it does include some significant materials that were published prior to 1978, but that were omitted from that edition. Emphasis in this supplement is on scholarly analysis of air power itself and scholarly depictions of its history. Like most editions of the United State Air Force Academy Directorate of Libraries' publication, Special Bibliography Series, this compilation is limited to current holdings of the Academic Library at the Academy. It includes books, reports, government documents, and journal articles. Excluded are pictorial works, newspaper articles, works of fiction, studies of the technology of aircraft and associated weaponry, and items focused on the general history of aviation. Readers wanting information on the history of aviation, certainly prior to the Wright Brothers, are encouraged to consult the U S. Air Force Academy Friends of the Library publication, The Genesis of Flight: The Aeronautical History Collection of Colonel Richard Gimbel.
