Cambridge Dictionary of American English Book and CD-ROM by Sidney I. Landau
The authoritative guide to American English as it's really used today. The Cambridge Dictionary of American English CD-ROM contains the full text of the printed dictionary, as well as spoken pronunciations for every word in the text to the entry where that word is defined; tools that allow users to add their own notes to the dictionary; and sophisticated lookup tools that let learners search by grammar code, part of speech, and usage label as well as by word. The CD-ROM can also be linked with Microsoft (R) Word to allow fast lookups from word processing documents.
