Step 2 of the research process often involves finding an overview of a topic, checking facts and data, checking dates of significant events, or looking up definitions of specialized terms. 
Like the roots of a tree, background information is not always visible but it does play an important role in your research. While Google can be helpful in this regard, you may find some of the UC Merced Reference Databases useful for definitions and background information. Spending time on this step of the process can help give you valuable context that will help you with other steps like searching for research and writing about your topic.
Tip: Background information is often called "reference information" in libraries and library databases.
