When you're searching for articles on a specific work in MLA International Bibliography, it's a good idea to be as specific as possible about what you are looking for. Using the dropdown menus next to the search bars can help you find articles on your work. For example, if you're looking for articles on The Closing Door by Angelina Grimke, you could search for all articles that list The Closing Door as the primary subject work. To make it clear you are looking for articles on Grimke's work, you might add "Grimke" in another subject line, and search for all works that list her as the primary subject author.
