This guide is organized by types of resources:

• Reference Sources - These sources provide important background and contextual information on your subject. Reference sources include bibliographies, dictionaries, encyclopedias, and handbooks. A reference source usually provides an overview of a topic without arguing for a specific perspective on the topic. You can use this type of source to help narrow your research topic, find data to support your thesis, and identify keywords and main ideas to use as search terms.
• Books and Scholarly Articles - These sources provide in-depth information on a topic while also arguing for a specific perspective on the topic. These types of sources are useful for analysis and for learning about scholarly perspectives on your topic.
• Data and Policy Sources - Sources for datasets, statistics and statistical analysis, and public policy documents.
