A THESAURUS OF EDUCATIONAL TERMS WAS PRODUCED TO PROVIDE A TERMINOLOGY BASE WHICH WOULD BE AMENABLE TO RAPID AND EASY MODIFICATION AND UPDATING. THE PRIMARY SOURCE OF TERMS WAS A SEMANTIC CODE DICTIONARY, PREVIOUSLY CREATED DURING THE INDEXING OF SOME 6,500 EDUCATIONAL RESEARCH DOCUMENTS. A FACETED STRUCTURE WAS CREATED. THE DISPLAY CONSISTED OF (1) AN ALPHABETICAL LIST, (2) A FACETED ARRAY, (3) A REPRESENTATIVE LIST OF IDENTIFIERS, AND (4) A PERMUTED DESCRIPTOR LIST. NOTES AND FIGURES WERE INCLUDED FOR USE OF THE FACETED DISPLAY. RECOMMENDATIONS INCLUDED WERE (1) THAT THE U.S. OFFICE OF EDUCATION MAKE OPERATIONAL TESTS, MODIFICATIONS, AND ADDITIONS BASED UPON THE SUGGESTIONS OF SUBJECT SPECIALISTS AND INFORMATION EXPERTS, AND (2) THAT INDEXERS AND SEARCHERS RECEIVE TRAINING IN THE USE OF THESAURUS SO THAT THEY WOULD BE ABLE TO EXPLOIT ITS FULL POTENTIAL.
