Eupheus Learning World Book Dictionary 2 Vol Set

The World Book Dictionary is a two-volume English dictionary published as a supplement to the World Book Encyclopedia. It was originally published in 1963 under the editorship of Clarence Barnhart, who wrote definitions for the Thorndike-Barnhart graded dictionary series for children, based on the educational works of Edward Thorndike whom Clarence Barnhart had known and worked with decades before. In some editions it was called the World Book Encyclopedia Dictionary. The writing and editing of special articles was carried out by the staff of the World Book Encyclopedia. Encyclopedia staff also reviewed the work for consistency with the encyclopedia and appropriateness of its users. Like the encyclopedia, it is designed to be user friendly to young people, yet comprehensive enough to be useful to adults. The definitions are designed with consideration for the age at which a person usually encounters the word. Quotations or sample sentences are offered with many words.
