Civil Law Sources
Constitutions, statutes and cases (judicial opinions) are the most common sources of civil law in the United States. These types of documents are called primary sources and together make up what the law is in a given jurisdiction (state or federial circuit).
Other legal writing such a encyclopedias, books (sometimes called treatises) and law reviews (scholarly articles) offer interpretations, analysis and recommendations about the law and what it ought to be. These secondary sources usually point to where you can find the law.
The databases listed below provide access to primary and secondary sources of civil law in the U.S.

Evaluating Sources
Being aware of the quality and biases of sources is critical to the research process. Carefully consider the following attributes about the sources you use.
- Authorship-Who is the author? What are her credentials and areas of expertise? Look for other publications by the author. Google or search broad databases him to see what you can learn about his activities or credentials.
- Purpose-What is the purpose of the writing? Is it to inform or persuade? A close reading is the best way to asertain purpose.
- Publication type-Is the publisher or web site popular or scholarly or devotional? If you are not sure, browse other writing by the publisher. What internal signals hint at the purpose such as the presence or absence of citations? If you are still unsure, you can ask the librarian for guidance.
- Point of view-Does the writing advocate for a particular point of view or does it strive for balance or objectivity? Web sites often have "about us" or mission statements that suggest points of view or sources of funding. Use a broad search engine such as the search box on the library home page or wikipedia to find out about how others characterize the publisher, author or site.
