March 194 1 FOREWORD to SUPPLEMENTARY BIBLIOGRAPHIES

Since the publication of the original fifty subjects of this Bibliography, many favorable comments have been received

as to its usefulness0 The demand from aeronautical organiza­ tions, both in the United States and abroad, for supplementary volumes bringing the subjects up to date, has been so great that authorization has been granted and funds allotted by the Work Projects Administration for that purpose^ This supplement­ ary volume is issued in response to this demands

The Project, sponsored by the Mayor of the City of New York, receives the cooperation of the Institute of the Aeronautical Sciences which directs the research and publishing staff workers„

DISTRIBUTION

Requests for these bibliographies have been received to such an extent that it has been impossible to supply the demand. Be­ cause of the limited number of copies published, distribution is necessarily restrictedo They cannot be sent to individuals or soldo Organisations desiring copies may apply for same by letter,

stating the use for which they are requiredD These requests will be considered in the order received* Should the supply be ex­ hausted, such requests will receive first consideration when addi­ tional copies are published,,
