Learn which scholars are important in your field
How do you learn who is important in your field? In addition to asking your professors and fellow students, you can also check citation indexes like Scopus and Web of Knowledge to see whose articles are cited most frequently. Run a keyword search for your topic and then sort by most cited. For books, go to Amazon and look at customer reviews. These reviews will often lead you to the core books in your field.
