Navigating through the various sources of literary criticism (the scholarly evaluation of literature including the critical discussion of novels, poetry, plays, and short stories) can be daunting.  Substantive criticism is found in books and journal articles, in print and online. 

Published bibliographies are an essential tool for finding the seminal critical articles that have been written about a major literary work over time.  Bibliographies can be found in reference books, handbooks and companions to particular authors or literary movements, scholarly editions of literary works, and critical articles. 

Indexes and databases will also help you identify articles in journals, anthologies and other published material regarding a particular literary work or author.
