Legal research is a cornerstone of the legal profession. Whether you’re a seasoned attorney, a paralegal, a law student, or even navigating a legal issue on your own, access to reliable and efficient legal research tools is paramount. In today’s digital age, the landscape of legal research has been revolutionized by sophisticated software and online platforms, offering unparalleled access to statutes, case law, regulations, and secondary sources. This blog post will explore the essential legal research tools available, their features, and how they can enhance your legal practice or personal understanding of the law.
The Cornerstones of Legal Research: Primary Law Resources
Understanding Primary Authority
Primary authority comprises the binding rules and precedents that courts must follow. Accessing these sources accurately and efficiently is the foundation of any legal research endeavor.
- Case Law: Judicial decisions from federal and state courts. This includes opinions, orders, and judgments that establish legal precedents.
Example: Finding relevant case law involves searching for cases with similar facts and legal issues to your current situation. Tools like Westlaw or LexisNexis allow for sophisticated keyword searching, citation analysis (Shepard’s and KeyCite), and filtering by jurisdiction, court level, and date.
- Statutes: Laws enacted by federal and state legislative bodies. These are codified into comprehensive collections, such as the United States Code (USC) for federal statutes and state-specific codes for state laws.
Example: If you’re researching a specific federal crime, you would consult the USC Title 18. Online platforms provide updated versions of these codes, with annotations linking to relevant case law and legislative history.
- Regulations: Rules promulgated by administrative agencies at the federal and state levels. These flesh out the details of statutory law and provide specific guidance on compliance.
Example: The Environmental Protection Agency (EPA) publishes regulations in the Code of Federal Regulations (CFR). Understanding these regulations is crucial for businesses operating in environmentally sensitive areas.
- Constitutions: The fundamental governing documents of the United States and individual states. They establish the framework of government and protect fundamental rights.
Example: Researching constitutional law involves understanding the text of the Constitution, as well as the Supreme Court’s interpretations of its provisions.
Navigating Legal Databases
Legal databases are essential platforms for accessing primary law. They offer powerful search capabilities and tools to help you efficiently find the information you need.
- Westlaw: One of the leading legal research platforms, offering comprehensive coverage of case law, statutes, regulations, and secondary sources. Features include KeyCite (a citator), WestSearch for natural language queries, and access to expert analysis.
Actionable Takeaway: Utilize Westlaw’s KeyCite to ensure the case law you’re relying on is still good law and hasn’t been overruled or questioned.
- LexisNexis: Another major legal research provider, offering a similar range of primary law and secondary sources. Features include Shepard’s (a citator), Lexis Advance for advanced search capabilities, and Practical Guidance modules for specific areas of law.
Actionable Takeaway: Explore LexisNexis’s Practical Guidance modules for step-by-step instructions and forms for common legal tasks.
- Bloomberg Law: A comprehensive legal research platform that integrates legal research with news, dockets, and analytical tools. It is known for its competitive pricing and focus on business and finance law.
Actionable Takeaway: Bloomberg Law is a good option if you need to research business-related legal topics and want to stay up-to-date on current events.
Delving into Secondary Sources: Expanding Your Understanding
Understanding Secondary Authority
Secondary authorities provide commentary, analysis, and explanation of primary law. While not binding, they are invaluable for understanding complex legal issues and developing legal arguments.
- Law Reviews: Scholarly journals published by law schools, featuring articles written by professors, practitioners, and students. They offer in-depth analysis of legal topics and can provide valuable insights into emerging areas of law.
Example: Searching law review databases (like HeinOnline or LexisNexis) can help you find articles discussing the nuances of a particular legal issue.
- Treatises: Comprehensive legal texts that provide a detailed overview of a specific area of law. They often include citations to relevant case law and statutes.
Example: “Prosser and Keeton on Torts” is a classic treatise on tort law, offering a thorough explanation of the elements of various torts and the relevant legal principles.
- Legal Encyclopedias: Broad overviews of legal topics, providing a starting point for legal research. Examples include American Jurisprudence 2d (Am Jur 2d) and Corpus Juris Secundum (CJS).
Example: If you’re new to an area of law, consulting a legal encyclopedia can help you get a general understanding of the relevant concepts and terminology.
- Restatements of the Law: Publications by the American Law Institute (ALI) that summarize and restate common law principles. While not binding, they are highly persuasive authority and often cited by courts.
Example: The Restatement (Second) of Torts is a widely respected source for understanding the principles of tort law.
Utilizing Secondary Source Databases
These databases provide access to a wealth of secondary source materials, making it easier to find relevant commentary and analysis.
- Westlaw and LexisNexis: Both platforms offer access to a wide range of secondary sources, including law reviews, treatises, legal encyclopedias, and Restatements of the Law.
- HeinOnline: A comprehensive database specializing in law reviews and legal history materials. It includes full-text access to hundreds of law reviews and other scholarly legal publications.
Actionable Takeaway: HeinOnline is a great resource for historical legal research and accessing hard-to-find law review articles.
- Google Scholar: While not a dedicated legal research platform, Google Scholar can be a useful tool for finding scholarly legal articles and other academic publications.
Actionable Takeaway: Filter your Google Scholar search by “legal opinions and journals” to focus your results on legal scholarship.
Free and Low-Cost Legal Research Options
Exploring Open-Access Resources
While paid legal research platforms offer comprehensive features, several free and low-cost options can be valuable for basic legal research.
- Google Scholar: As mentioned earlier, Google Scholar can be used to search for legal scholarship. It also provides access to some case law, though coverage may be limited.
Example: You can search for cases by citation or keyword and often find links to court websites where you can access the full text.
- Fastcase: A legal research service available through many bar associations and law libraries. It offers access to case law and statutes, with a user-friendly interface.
- Caselaw Access Project (CAP): A project of Harvard Law School Library that provides free access to digitized case law from all U.S. jurisdictions.
Actionable Takeaway: The CAP is a valuable resource for historical case law research and accessing primary legal materials without cost.
- Govinfo.gov: This website provides access to official publications from the U.S. Government Printing Office, including statutes, regulations, and legislative materials.
Actionable Takeaway: Govinfo.gov is a reliable source for accessing official versions of federal laws and regulations.
Leveraging Public Law Libraries
Public law libraries offer access to a range of legal resources, including books, journals, and online databases. They often provide research assistance from qualified librarians.
- Access to legal databases: Many public law libraries subscribe to Westlaw, LexisNexis, or other legal research platforms, providing access to these resources for free or at a reduced cost.
- Expert assistance: Law librarians can help you navigate legal research tools and find relevant information.
- Quiet study space: Law libraries offer a dedicated space for legal research and study.
Advanced Research Techniques and Tips
Mastering Boolean Search Operators
Boolean operators (AND, OR, NOT) allow you to refine your search queries and retrieve more relevant results.
- AND: Narrows your search by requiring both terms to be present in the results.
Example: “negligence AND slip and fall” will find cases where both terms are mentioned.
- OR: Broadens your search by including results that contain either term.
Example: “dog OR canine” will find cases that mention either “dog” or “canine.”
- NOT: Excludes results that contain a specific term.
Example: “contract NOT employment” will find cases about contracts that do not involve employment.
Utilizing Natural Language Processing (NLP)
Many legal research platforms now incorporate NLP, allowing you to search using natural language queries rather than complex Boolean expressions.
- Westlaw’s WestSearch and LexisNexis’s Lexis Advance: These tools allow you to type in a question or statement in plain English and receive relevant search results.
Example: Instead of typing “negligence AND slip and fall,” you can type “What is the duty of care owed by a property owner to a visitor in a slip and fall case?”
- Benefits of NLP:
Easier to use for novice researchers.
Can uncover relevant cases and authorities that might be missed with traditional search methods.
* Helps to refine searches and identify key issues.
Citation Analysis and Tracking
Citation analysis tools, like KeyCite and Shepard’s, help you determine the precedential value of case law and ensure that your research is up-to-date.
- KeyCite and Shepard’s: These citators track the history and treatment of cases, indicating whether they have been affirmed, reversed, overruled, or questioned.
- Alerts and Tracking: Most legal research platforms allow you to set up alerts to track changes in case law or statutes, ensuring you stay informed about new developments in your area of law.
Conclusion
Legal research tools are indispensable for legal professionals and anyone seeking to understand the law.
