PUNCH-CARD INFORMATION RETRIEVAL SYSTEMS FOR FLASHBLINDNESS PROTECTION RESEARCH. I. PHOTOCHROMIC MATERIALS.

Abstract

The information retrieval system described was set up to include photochromic materials, organic semiconductors, image converter devices, and other protective systems. Two types of data are coded in the system: (1) general information; including authors, publications, dates, and comments. (2) Specific data for individual compounds and subjects. The specific data described in this report pertain to photochromic materials, the area of present in-house research at the U. S. Army Natick Laboratories (NLABS). Subject and compound codes for other areas will be prepared and reported separately when needed. Methods for coding the data on 5 x 8-inch, double-row hand punch cards are presented. Information is retrieved in any order by sorting the coded cards for subjects, authors, dates, and publications, thus providing a versatile system for obtaining any information previously coded.
