Each entry varies in length depending on the term, concept, or person being described. Six longer essays describe the history of the branches of mathematics. The writing style is straightforward and readable and sometimes contains parenthetical notes that add background or context. If an entry contains a word or words in capital letters, that term or person is also an entry in the encyclopedia.
This source would be useful in a high-school library, public library, and academic library as a basic resource for students who wish to have a better understanding of simple or not-so--simple mathematical concepts. It is hoped that the author is rewarded in his goal of encouraging mathematics students to go beyond rote memorization of mathematical steps or skills. This encyclopedia will certainly assist them toward that goal. Kathryn O'Gorman
