THE AVAILABILITY OF STUDENTS AT THE UNIVERSITY OF DAYTON HAD SUGGESTED THEIR POSSIBLE USE AS INDEXERS FOR INDEXING DOCUMENTS FOR THE AEROSPACE MATERIALS INFORMATION CENTER (AMIC). A STUDENT HAD BEEN EMPLOYED TWO YEARS AGO AND INFORMALLY TRAINED IN INDEXING. THE SUCCESS OF THAT EXPERIENCE, THE SUCCESSFUL DEVELOPMENT OF A CONTROLLED VOCABULARY, AND THE NEED FOR ADDITIONAL INDEXERS LED TO THE INAUGURATION OF A FORMAL INDEXER TRAINING PROGRAM FOR UPPERCLASSMEN. THE DESIGN, IMPLEMENTATION AND EVALUATION OF THE TRAINING PROGRAM ARE DESCRIBED. IT WAS CONCLUDED THAT STUDENTS CAN BECOME PROFICIENT INDEXERS. MODIFICATIONS WERE MADE TO IMPROVE THE VARIOUS OPERATIONS OF THE RETRIEVAL SYSTEM--THE AMIC SYSTEM WAS TRANSFERRED FROM THE UNIVERSITY'S NCR 304 COMPUTER TO THE GOVERNMENT'S IBM 7094 COMPUTER FACILITIES AT WRIGHT PATTERSON AIR FORCE BASE, MODIFICATIONS WERE MADE IN THE VOCABULARY AND THESAURUS TO MAKE THEM EASIER TO USE AND TO SAVE PROFESSIONAL TIME. MICROFILM EQUIPMENT WAS INSTALLED TO INCREASE THE EFFICIENCY OF SCREENING SEARCH OUTPUTS. ADDITIONAL STUDIES HAVE COMMENCED WHICH WILL LEAD TO FURTHERING THE EFFICIENCY AND EFFECTIVENESS OF THE OVERALL SYSTEM.
