REFERENCE LITERATURE 



A wealth of information, published and otherwise, is available to pro- 

 vide further details of the various aspects of this project as covered in 

 this history, and most of it is listed in AppendixIV. Some of this information 

 accompanies this report in the form of various appendices --either because 

 the information is so closely associated with history that it should become, 

 at least to that extent, a part of it, or because it would be difficult to refer 

 to otherwise. 



A summary of other types of supplemental information follows: 



1. Government Reports . The various quarterly, final, and occasional 

 reports made by the General Electric Company to the Government summarize 

 the work conducted under various Government contracts. These reports have 

 all been printed and are available in General Electric libraries and files. 



2. Articles & Papers . Many articles and papers have been prepared 

 by members of Project Cirrus, especially members of the Research Group, 

 for printing in periodic publications or for delivery before scientific and 

 other bodies. Some of these, covering significant developments or making 

 helpful summaries of progress but not specifically included in the reports 

 to the government, are listed in Appendix IV. 



3. Laboratory Records . A further wealth of detailed information is 

 to be found in the normal records of the Research Laboratory. In partic- 

 ular, the notebooks maintained by the individual workers in the project can 

 be consulted. In addition to these are the reports of the Steering Committee 

 and the Operations Group of Project Cirrus, copies of some or all of which 

 are in the possession of Langmuir, Schaefer, and Maynard. Still other infor- 

 mation can be obtained from letterbooks, contract folders, and accounting 

 records. 



4. Langmuir 's Records . A great deal of pertinent information has 

 been gathered together by Langmuir as the basis of his various analyses 

 and mathematical calculations, particularly in connection with his running 

 controversy with the Weather Eureau. One such collection'^") ft as already 

 been mentioned. Another'! 1 ?) is a collection of unpublished letters and 

 reports on the general subject of the seven-day periodicity in the weather 

 during 1950. Eoth of these documents are to be found in Langmuir's office 

 files at The Knolls.
