The procedures for compiling a new elementary word list using computers are described. Words were taken from 127 books in fourteen series of widely used elementary textbooks. The compilation procedures consisted of (1) input: putting the lists into the computer, (2) processing of the vocabulary into compiled lists, (3) output: production of the actual word lists. Rules set up to determine whether inflected forms of words would be included are described. Capitalized proper nouns, abbreviations, word parts, and hyphenated words were deleted. Scanning programs were used to correct and proofread initial lists. The processing of the words resulted in four kinds of lists: (1) the Core List (words which were included in three or more of the six reader series), (2) the Additional List (words found in four or more different series excluding Core words), (3) four Technical Lists, and (4) a Total Alphabetical List in which all the lists were merged and put in alphabetical order. A comparison between this list and four other word lists is made. Sample printouts, tables of data, and references are included. (AL)
