How to do Research on Law

Academic Writing Service

Law Research Guide 1How to do research on law? Laws are enacted for the purpose of governing society. These include local, state, and federal codes, legislation, regulations, and court decisions that have either upheld or rewritten longstanding laws. There are also various consumer laws, labor laws, family laws, bankruptcy laws, laws for renting and selling a home, or leasing and purchasing a used car, and city ordinances banning smoking in public places or the use of certain trash receptacles.

Fortunately, many legal resources have been published, including hundreds of indexed and full-text articles in major law reviews, legal newspapers, bar association journals, and international law publications delivering authoritative and critical accounts on notable people, trials, and other legal topics for research papers.

Available in both print and electronic form, most of the above resources can be found at your local public and college and university library, or university law library, as well as on the World Wide Web. Recommended references follow.

Selected Subject Headings

Listed below is a sample of a few broad Library of Congress subject headings—made up of one word or more representing concepts under which all library holdings are divided and subdivided by subject—which you can search under and use as subject terms as well when searching online library catalogs for preliminary and/or additional research, such as books, audio and video recordings, and other references, related to your research paper topic. When researching materials on your topic, subject heading searching may be more productive than searching using simple keywords. However, keyword searching when using the right search method (Boolean, etc.) and combination of words can be equally effective in finding materials more closely relevant to your research paper.

Selected Keyword Search Strategies and Guides

Most online library indexes and abstracts and full-text article databases offer basic and advanced “keyword” searching. In this case, combine your keyword terms of your thesis question or topic with relevant subject headings using the Boolean search method (employing “and” or “or”) to find research appropriate to your research paper topic.

If your topic is “illegal immigrants and welfare,” for example, enter “illegal immigrants” and “welfare” with “and” on the same line to locate sources directly compatible with the primary focus of your paper. To find research on more specific aspects of your topic, from your list of keywords that you developed alternate with one new keyword at a time in between (for example, “illegal immigrants and eligibility and welfare,” “illegal immigrants and laws and welfare,” “illegal immigrants and rights and welfare,” “illegal immigrants and restrictions and welfare,” etc.).

For additional help with keyword searching, navigation or user guides for online indexes and databases by many leading providers—including Cambridge Scientific Abstracts, EBSCO, H.W. Wilson, OCLC, Ovid Technologies, ProQuest, and Thomson Gale—are posted with direct links on library Web sites to guides providing specific instruction to using whichever database you want to search. They provide additional guidance on how to customize and maximize your search, including advanced searching techniques and grouping of words and phrases using the Boolean search method—of your topic, of bibliographic records, and of full-text articles, and other documents related to your research paper.

Selected Source and Subject Guides

 Law Research Guide 2As part of your preliminary research to find appropriate resources for your research paper, information source and research guides are available at most public and academic libraries and are keyword searchable through your library’s online catalog (to search and locate guides, enter your “subject” followed by these keywords one search at a time: “information sources,” “reference sources,” and “research guide”). Printed guides available for this subject area include

Each guide lists more recommended published and Web sources—including books and references, journal, newspaper and magazines indexes, full-text article databases, Web sites, and even research tutorials—that you can access to expand your research on more specific issues and relevant to your chosen paper subject.
