For some examples, review the URI Academics page "Schools, Departments, and Programs." All of these fields of knowledge fall into one of the three major disciplines:

• Humanities

• Social Sciences

• Sciences

To help get you started on the research process, it will help to clarify how the major areas of knowledge are defined, especially in the beginning stages when you are not quite sure of the terms that are used in the literature. It will help when you begin to gather information by making it easier to identify some broad-based sources like encyclopedias.

Humanities
“The branches of learning (as philosophy, arts, or languages) that investigate human constructs and concerns as opposed to natural processes (as in physics or chemistry) and social relations (as in anthropology or economics)”

Social Sciences
“A science (as economics or political science) dealing with a particular phase or aspect of human society.”

Sciences
“Knowledge or a system of knowledge covering general truths or the operation of general laws especially as obtained and tested through scientific method; such knowledge or such a system of knowledge concerned with the physical world and its phenomena.”
