Allen Ginsberg has been used for this example but you can swap "Ginsberg" for the last name of the author you are researching. Keep all of the other terms. This search will look for information with the word "poetry" in the subject. This tells the database to only bring back information that will be relevant for this assignment.
Pay attention to the subjects section in the item's record page. This tells you a lot about the book/article and it also gives you search terms to add to your search term bank. If you click on any of these links in the record page, it will show you all the books/articles that have been "tagged" the same way.
In databases such as MLA International Bibliography and Literature Resource Center, you can search precisely for articles about an author and a work by that author. Databases do not always use the same words to describe the same search field. MLA International Bibliography uses SA: Primary Subject Author to search for a specific author whereas Literature Resource Center uses Person By or About to describe the same thing. Be aware of the differences.
