An indispensable tool for the Information Age, when quick, concise communication is vital, The Barnhart Abbreviations Dictionary is your fastest, easiest, and best source. Authoritative and up-to-date, with more than 60,000 entries, this innovative volume is a landmark of its kind. Materials have been gathered from general interest newspapers, books, and magazines, and a wide array of technical publications, among other sources.

Beyond the scope of its contents, however, what separates this dictionary from similar reference works is its user-friendly, two-way format. Readers may look up an abbreviation to find out what it stands for, or - equally important - may look up a term or phrase to learn how to abbreviate it.
