"Students and scholars of the Muslim world will find much useful information here. Academic and public libraries will benefit from having this set, as could high school libraries. Librarians might consider retaining the 2004 volumes as well."
"The source is greatly expanded in coverage from a decade earlier, providing new or updated articles for about half of the content, including over 350 color images and maps....These updates have improved an already stellar resource, and the second edition should be considered for any library collection serving beginning students.
