A listing of approximately 600 words or phrases descriptors is provided for use in indexing and retrieving civil defense research information. Inclusion notes, Use, and Also see references are provided as well as general directions for applying descriptors to civil defense information. The descriptor selection was modeled on the system of the Defense Documentation Center DDC. About 70 of the 600 descriptors are not used by DDC. They were chosen from the Civil Defense Matrix and from special fields of interest. This core of 600 general descriptors can be supplemented with specific terms in the subject areas where the quantity of documents warrants more intensive indexing. From previous library experience PB-166 415, it is estimated that the 600 descriptors chosen are the minimum number needed for a collection of 1000 documents. Author
