Once you have identified the main topic and keywords for your research, find one or more sources of background information to read. These sources will help you understand the broader context of your research and tell you in general terms what is known about your topic. They can give you an idea of how much and what kind of information is available on a given topic.
Encyclopedias and dictionaries: You can find subject-specific encyclopedias and dictionaries by using the library catalog or by asking a reference librarian.
Cull from bibliographies: Often there are scholarly articles that give an overview of research in specific fields. The sources cited in the bibliography are good starting points for further research.
