The Charlie Brown Dictionary is a new dictionary based on a classic model - The Rainbow Dictionary, published originally in 1947 and in a new copyright edition in 1959, and a bestseller in its field since publication.

The present dictionary is new in both its illustrations and its definitions, but the vocabulary is largely that of The Rainbow Dictionary, with additions and deletions reflecting changes in the language that children hear, speak and read. the concept of the dictionary also remains unchanged: youngsters should enjoy the use of a dictionary. They should find it a source of pleasure so that, as they grow, they will easily turn to more advanced dictionaries as a source of knowledge.
