Start with GCC's Primo search or databases listed by subject, found here. For Poe, you might want to look through the General, English & Literature, or Historical databases.
Helpful Hint!
When looking up content, I recommend searching Poe AND whatever topic you are wanting more information about. Utilizing Boolean Operators in your search can help you get better results! Boolean operators are words like AND, OR, and NOT used in search queries to refine results. AND narrows results by requiring all terms to be present, OR broadens results by including any of the terms, and NOT excludes specific terms from the results. Quotation marks provides results with the exact phrase.
For Example: Poe AND grief, Poe AND isolation, or "Edgar Allan Poe" AND Annabel Lee, etc.
