This comprehensive catalog facilitates rapid location of plays appearing in English in both textbooks and anthologies published between 1900 and 2000. Included are multivolume sets from series that began in the 20th century but were completed after 2000. In addition to correcting errors from previous editions, Montgomery (library science, Valdosta State Univ.; Yale Book of Quotations), who revived the guide after a 20-year interval, has nearly doubled the number of playwrights included and expanded the scope to consider 744 collections. Her experience as an interlibrary loan librarian has permitted her location of English publications in 103 countries, thus adding another 3,593 new plays to the previous edition’s 6,548. Essential for English literature collections.
