INTRODUCTION.

This work covers the literature published from January 1, 1917, to December 31, 1919, and continues the work of the Smithsonian Institution issued as volume 55 of the Smithsonian Miscellaneous Collections, which covered the material published prior to June 30, 1909, and the work of the National Advisory Committee for Aeronautics as published in the Bibliography of Aeronautics for the years 1909 to 1916.

The interruption to international exchanges due to the war and the great difficulty encountered subsequent to the armistice in collecting publications considered secret or confidential in character at the time of their issuance, have accounted for the delay in the preparation of the Bibliography of Aeronautics for the years 1917, 1918, and 1919.

As in the Smithsonian volume, and in the Bibliography of Aeronautics for the years 1909 to 1916, citations of the publications of all nations have been included in the languages in which these publications originally appeared. The arrangement is dictionary form with author and subject entry, and one alphabetical arrangement. Detail in the matter of subject reference has been omitted on account of the. cost of presentation, but an attempt has been made to give sufficient cross reference for research in special lines.

The National Advisory Committee for Aeronautics will next present a bibliography for the years 1920 and 1921 in one volume, and it is the committee's intention to publish a Bibliography of Aeronautics annually thereafter.
