A GUIDE FOR PREPARING BILINGUAL DICTIONARIES WAS DEVELOPED, EMPHASIZING PROPER METHODS FOR SELECTING DICTIONARY ENTRIES. ASSUMED PURPOSES OF BILINGUAL DICTIONARIES WERE CONSIDERED IN CHOOSING THE SELECTION CRITERIA. A LIST OF POSSIBLE CRITERIA WAS PRESENTED, CENTERING ON THE FORM, SYNTAX, AND MEANING OF WORDS CONSIDERED FOR SELECTION AND THE FREQUENCY OF WHICH THESE WORDS ARE USED. IT WAS SUGGESTED THAT BILINGUAL DICTIONARIES OF INDO-EUROPEAN LANGUAGES SHOULD CONTAIN A MINIMUM OF 5,000-10,000 ENTRIES. THIS REPORT IS ONE OF A SERIES OF 13 PAPERS PRESENTED AT A CONFERENCE ON LEXICOGRAPHY, INDIANA UNIVERSITY, NOVEMBER 11-12, 1960. (JH)
