Finding criticism of specific poems or stories can sometimes be difficult. If you're stuck, try searching the bibliography and index tools in the next column, or these print reference books can also be helpful:
Reference PN1010 .P499
Short Story Criticism
Reference PN3373 .S386
Both are indexed in Literary Index.
Listed here are general bibliographies and indexes. For more specific bibliographies see A Guide to Serial Bibliographies for Modern Literatures, Reference PN695 .W67 1995.
To find works dedicated to research on an author, do a subject search on the author's name, last name first.
A keyword search on the author's name will find these works, plus works by the author, and sections of more general works.
Online text collections deliver more detailed results than the library catalogs.
