To find criticism of a literary work, search the MLA International Bibliography for your topic, author or literary work. You can combine keywords (i.e. "Gabriel Garcia Marquez" and "magical realism") to limit your list of results. You can also limit your results by language.
To narrow things down, you can also choose to search with the fields "Primary Subject Author" (for your author) and "Primary Subject Work" (for the work of literature).
You can also find literary criticism on your author or work in OneSearch by performing a subject search with this formula
You can use OneSearch to find primary sources. You can do a keyword search for the name of the person, but a more focused way to search for biographical sources is to choose "Library Catalog" at the top of the search page, choose "Subject" from the drop down list, and then put the name of the person in the search box in this format "LastName, FirstName" (ex. "Allende, Isabel") and then choose "Subject" on the next line and put in the term "Criticism and Interpretation".
The results will be all the materials we have in the library that are about that author and his or her works. Some of those materials may be a single-authored book about the topic, some of them may be edited volumes, where each chapter has a different author.
