Find primary theoretical sources can be tricky, but it doesn't have to be!
Try these methods to read seminal works by key literary theorists:
Use secondary sources, such as your Norton Anthology of Theory and Criticism, or books covering literary theories at a broad level like those in the Explore Different Literary Theories tab, as a springboard to finding primary theoretical sources. They have excellent bibliographies of primary sources at the end of each chapter or book, usually organized by theorist, theory, or chronology.
Look at the Author Bibliographies section towards back of the book. Organized alphabetically, each entry includes a description of the author's major works, their published literary criticism, and even interviews. (The entries also contain lists of secondary sources about the author, including biographies, guides to their life and works, and literary overviews and critical surveys).
Other literary theory books, especially those that focus on one literary theory in their entirety, often include bibliographies at the back of the book. A great series for this kind of research is the New Critical Idiom series by Routledge (linked in your Canvas course).
You can also find works by key theorists by doing an author search. (Keep in mind, an author search will bring up all works by the theorists, including their novels if applicable).
