[An] authoritative reference work. . . .Adamec doesn’t shy away from the current conflict in the Islamic world between ‘literalists’ and ‘modernists’ and includes both ‘radical Islamists and their opponents’ in his sometimes brutally honest, yet fair and objective, survey. Meant to be ‘a concise dictionary of Islamic history, religion, philosophy, and political movements,’ this third edition contains many new entries and expands on existing ones. With more than 700 entries (or approximately 480 pages), this edition appears to contain approximately 40 percent more information than the last (at over 340 pages of entries). . . .Changes to the third edition include a newly updated chronology through 2015, adding major events from the last decade. Other features include an appendix containing population statistics by region and country, both in absolute numbers and as a percentage of the total population for each country and world region. . . .This edition also contains a quick-reference glossary of Islamic terms, and it closes with an extensive, updated themed bibliography listing over 125 new sources covering the major Muslim geographic areas and a variety of subtopics. These will be useful to the serious scholar.
