This paper provides a fairly detailed corpus-based vocabulary profile of the Iranian EFL books used in public schools. To this end, the WordPerfect files of all the seven books were converted to text format to get rid of the formatting features and be compatible with the software used for analysis. The software tools used were the Compleat Lexical Tutor suite, version 6.2 (Cobb, 2011), AntConc (Anthony, 2012), and AntWord Profiler (Anthony, 2012). The output of the analysis included general counts of words in Iranian school books at different levels, the frequent function and content words, frequent n-grams, frequent metalinguistic words, the coverage of several well-known, corpus-based word lists in these books, the range of the words across the books, and the amount of vocabulary recycling. The paper discusses the vocabulary representativeness and recycling and the adequacy of exposure to English in these EFL books. Detailed word frequency tables as well as some practical implications of the quantitative results constitute important features of this article
