The document discusses strategies for narrowing research topics using subject-specific databases. It begins by outlining workshop goals of identifying different source tools, comparing sources found in tools, and learning strategies for narrowing topics. Users are then directed to a library website to access subject-specific databases and catalogs. An example of narrowing the broad topic of "food labeling" is provided, such as focusing on the evolution of regulations in the USA, innovative regulations in Sweden, or the influence of food lobbyists on FDA regulations in the United States. Users are also given an exercise to create a topic map starting from the original topic of "food labeling regulations in United States versus Europe".
