There are 111 pages in this book. It is a dictionary. A dictionary is a single-volume or multivolume reference work containing brief explanatory entries for terms and topics related to a specific subject or field of inquiry, usually arranged alphabetically (example: Dictionary of Neuropsychology). The entries in a dictionary are usually shorter than those contained in an encyclopedia on the same subject, but the word "dictionary" is often used in the titles of works that should more appropriately be called encyclopedias (example: Dictionary of the Middle Ages in 13 volumes).
