Chapter 5: Secondary Authority and other Research Resources--Encyclopedias, Treatises, American Law Report, Digests, Shepard's

According to Legal Research, Analysis, and Writing, 4th edition:

"Legal Encyclopedias are designed to provide an overview of all the areas of law. They not provide the in-depth coverage that is available in a treatise or periodical article." (p. 143)

"The two national encyclopedias are American Jurisprudence Second, commonly known as Am. Jr. 2d. and Corpus Juris Secundum, or CJS.  Both of these encyclopedias are national in scope; they present a general overview of federal and state law....Each encyclopedia covers more than 400 legal topics....CJS attempts to include every case reported in its discussion of topics, resulting in many pages having one or two sentence of narrative, with the rest of the page consisting of footnotes to cases....Am. Jr. 2d. is more selective in its inclusion of cases, presenting a cross-section of leading cases" (p. 144)

According to Legal Research, Analysis, and Writing, 4th edition:

"Treatises are texts that provide a comprehensive analysis of a single area of law, such as torts or criminal law.  Where a legal encyclopedia presents a broad overview of an area of law, a treatise does much more. It provides a much greater in-depth discussion of the law and will explain, analyze, and criticize the law.  Some treatises include guidance for the legal practioner, such as practice tips, checklists, and legal forms."

The digest provides the citation to and a brief summary, or digest, of all the court opinions that have addressed the subtopics. The ability to review the case summaries allows the researcher to select the case most similar to the client's case, that is, the case most on point. Thus, a digest serves as a tool for locating cases on specific questions being researched." (p. 163)

West's Illinois Digest

Allows one to search alphabetically by topic for relevant Illinois state and federal court decisions reported from 1938 to date.

print edition:

  • call number:  KFI 1247.1.I3 ser.2 - located on floor 4 (print edition is no longer updated)

online edition:

  • unavailable as individual title in Westlaw--follow directions below to search specifically for Illinois cases

According to Legal Research, Analysis, and Writing, 4th edition:

"When you locate primary authority that provides an answer to a question being researched, it is necessary to determine if the authority has been reversed or modified by subsequent law or court decision. That is, you must determine if the authority is still valid, if it is still "good law."  The first step to ensuring an authority is "good law" is to use a citator.  The two most common citators are Shepard's Citations, in print or online (Lexis) or Westlaw's KeyCite....The process of consulting a Shepard's source to determine the current validity of an authority is called Shepardizing.  You Shepardize a case or statute when you check it in Shepard's Citations.  However, today that term is used whether you are using Shepard's or you are using Westlaw's KeyCite." (p. 172-73)
