Dr, Paul Henshaw DR. HENSHAW wes introduced to discuse the development of scientific category classification system which he tas been working on for some time. It has been agreed that the research within the DEM program should be classified and SCIENTIFIC CATEGORY CLASSIFICATION recorded in a manner that would make the information readily available. After much study, it was decided to employ McBee Keysort cards at least as a beginning and then if the volume of material and its use warranted, the system could then be transferred to punch cards to be used in an IBM Machine. A sample of the card to be used is included as Appendix C. It is estimated that there are between five hundred and one-thousand projects in operation within the national laboratories in addition to between a thousard and fifteen hundred in research contracts. DR. HENSHAW reviewed similar card systems used at Brookhaven (in the field of the Effects of Radiation on Plants) and by Dr. Hollander in Oak Ridge. He also told of the effort of the Bureau of Standards to simplify patent searches employing a similar method. DR. BUGHER pointed out that the keysort type of card is very helpful and practicable for comparatively small operations, but for large programs, even the IBM type of card can become inadequate because of the high scanning speeds required. He pointed out the high rate at which scientific literature is being increased. DR. GLASS told of his experience in editing SCIENCE. In this case it was advantageous tc obtain identifying key terms, phrases, and from the authors for the purpose of classifying the report indexing. He suggested that it might be useful to require found ideas for the con- tractors and their advisors to classify their own work rather than depending upon the DBM staff to do it. DR. HENSHAW proposed supplying contractors with a catalogue of activities for the purpose of assisting the contractors in classifying their own programs. References were made to thelibrary service to be initiated by the Ford Foundation in Washington and also the Biological Chemical In- formation Services also in Washington with which this program might be eventually integrated. DR. SHILLING and his staff were congratulated on their efforts and on the great amount of work which had been done within the last four months to solve a number of problems raised at the last ACBM meeting. (The meeting was adjourned for a brief recess.)
