🧑🏾💼Advanced Legal Research Unit 7 – Electronic Legal Research Methods
Electronic legal research has revolutionized how lawyers find and analyze legal information. Online databases like Westlaw and LexisNexis provide comprehensive access to primary and secondary sources, enabling efficient searches of case law, statutes, and regulations.
Mastering electronic research methods is crucial for legal professionals. Key skills include using Boolean operators, navigating online databases, evaluating source credibility, and properly citing electronic sources. These techniques allow researchers to quickly find relevant authorities and stay current on legal developments.
Electronic legal research involves using online databases and resources to find legal information, including case law, statutes, regulations, and secondary sources
Primary sources are the law itself, such as cases, statutes, and regulations, while secondary sources provide commentary, analysis, and explanations of the law (treatises, law review articles, legal encyclopedias)
Subscription-based databases, such as Westlaw, LexisNexis, and Bloomberg Law, offer comprehensive legal resources and advanced search capabilities
These databases require paid subscriptions and are commonly used by legal professionals and law students
Free online legal resources, such as Google Scholar, Findlaw, and government websites, provide access to some legal information at no cost
Citators, like Shepard's (LexisNexis) and KeyCite (Westlaw), help determine the current status of a case or statute and identify related authorities
Headnotes are summaries of key legal points in a case, often assigned by the database's editorial staff, which can be used to find similar cases
Annotations are notes added to statutes or regulations that provide summaries of relevant case law, analysis, and cross-references to related provisions
Electronic Legal Databases Overview
Westlaw, LexisNexis, and Bloomberg Law are the three major subscription-based electronic legal databases used in the United States
These databases offer extensive coverage of case law, statutes, regulations, and secondary sources
They provide powerful search engines, citators, and tools for organizing and analyzing legal information
Westlaw is known for its Key Number System, which organizes case law by legal topics and subtopics, making it easier to find relevant cases
LexisNexis offers a comprehensive collection of secondary sources, including treatises, law reviews, and news sources
Bloomberg Law integrates legal research with business and financial information, making it useful for corporate and transactional law
Free databases, such as Google Scholar and Cornell's Legal Information Institute (LII), provide access to some case law and statutes
These resources may have limitations in coverage, currency, and search functionality compared to subscription-based databases
Many courts and government agencies maintain websites with access to their own case law, statutes, and regulations
Specialized databases focus on specific areas of law, such as HeinOnline for law journals and treaties, and PLI for continuing legal education materials
Search Strategies and Techniques
Develop a research plan by identifying key issues, relevant jurisdiction, and time frame before beginning an electronic legal research project
Use secondary sources to gain an overview of a legal topic and identify primary sources to explore further
Utilize headnotes and annotations to locate relevant cases and statutes related to a specific legal issue
Employ both natural language and Boolean searches to find relevant authorities
Natural language searches use plain language phrases and allow the database to determine relevance
Boolean searches use connectors like AND, OR, and NOT to create precise search queries
Narrow searches by jurisdiction, date range, and document type to refine results and find the most relevant authorities
Expand searches by following links to related documents, such as cases cited within a decision or statutes referenced in an annotation
Take advantage of search filters, such as those for specific courts, judges, or attorneys, to further refine search results
Use citators to update research and ensure that cases and statutes are still good law
Boolean Operators and Advanced Filtering
Boolean operators (AND, OR, NOT) allow researchers to create precise search queries by connecting keywords and phrases
AND narrows search results by requiring all terms to be present
OR expands search results by including any of the connected terms
NOT excludes documents containing the specified term
Proximity connectors (e.g., /s, /p, /n in Westlaw; w/s, w/p, w/n in LexisNexis) specify the desired distance between search terms
/s or w/s requires terms to be in the same sentence
/p or w/p requires terms to be in the same paragraph
/n or w/n requires terms to be within a certain number of words of each other
Wildcards and truncation symbols (e.g., *, !) can be used to search for variations of a word or phrase
Quotation marks around a phrase search for the exact phrase rather than the individual words
Parentheses group search terms and connectors to create more complex queries
Field searching allows researchers to limit searches to specific parts of a document, such as the title, author, or date
Advanced filtering options, such as jurisdiction, court, and date range, help narrow search results to the most relevant documents
Navigating Case Law and Statutes Online
Use headnotes and topics to identify relevant cases within a database
Headnotes summarize key legal points and are often organized by topic or key number
Clicking on a headnote or topic link will retrieve other cases discussing the same legal issue
Utilize case citators (Shepard's or KeyCite) to find later cases that have cited the case being researched
Citators also indicate the treatment of the case, such as whether it has been overturned, distinguished, or followed
Search for cases by party name, citation, or docket number if known
Access statutes through databases' statutory collections or by using citation services like Westlaw's StatutesPlus or LexisNexis' Shepard's Statutes
Navigate statutory codes by browsing titles, chapters, and sections or by using the database's search functions
Use annotations to find cases interpreting or applying specific statutory provisions
Track the legislative history of a statute through session laws, bill texts, and committee reports, which are often available in electronic databases
Monitor pending legislation and recently enacted laws through databases' legislative services and alerts
Citing Electronic Sources
Follow the citation style required by your jurisdiction or the specific legal writing project (e.g., Bluebook, ALWD)
Include the name of the database and the unique identifier or citation assigned by the database when citing electronic sources
Example: Smith v. Jones, 123 F. Supp. 2d 456 (D. Mass. 2000), available on Westlaw at 2000 WL 123456
Provide the date the electronic source was accessed, as online content may change over time
Use "last visited" or "last updated" date for websites and online articles that do not have a traditional publication date
Cite online versions of print sources, such as law review articles or treatises, similarly to their print counterparts, but include the database name and identifying information
When citing electronic sources in court filings or other legal documents, verify local court rules for any specific requirements or preferences
Maintain consistency in citation format throughout a legal writing project
Double-check citations for accuracy and proper formatting before submitting legal work
Evaluating Online Legal Resources
Assess the authority of the source by considering the reputation of the database, publisher, or author
Subscription-based databases like Westlaw and LexisNexis are generally considered highly authoritative
Government websites and databases are official sources for statutes, regulations, and case law
Evaluate the scope of coverage, including jurisdictions, time periods, and types of legal materials included
Consider the currency of the information and how frequently the database or website is updated
Look for "current through" dates or update schedules to determine the timeliness of the content
Examine the accuracy and reliability of the information by comparing it to other reputable sources
Assess the ease of use and search functionality of the database or website
User-friendly interfaces, robust search options, and helpful tools like citators and annotations can enhance the research experience
Consider the cost and accessibility of the resource, especially when choosing between subscription-based and free sources
Consult with librarians, professors, or experienced legal professionals for guidance on the strengths and limitations of specific online legal resources
Practical Applications and Case Studies
Scenario 1: A criminal defense attorney researching a Fourth Amendment search and seizure issue
Begin by searching for relevant headnotes and key numbers in Westlaw or LexisNexis
Refine the search by jurisdiction (e.g., U.S. Supreme Court, state supreme court) and date range
Use citators to find more recent cases and assess the current status of key precedents
Consult secondary sources, such as treatises and law review articles, for in-depth analysis of the issue
Scenario 2: A law student writing a research memo on a contract law problem
Start with a broad search using key terms related to the contract law issue
Narrow the search by applying filters for jurisdiction, court level, and date range
Use Boolean connectors and proximity searches to find cases with fact patterns similar to the research problem
Review statutory provisions and annotations related to the contract law issue
Cite check cases and statutes using Shepard's or KeyCite to ensure they are still good law
Scenario 3: A legal scholar researching the legislative history of a federal statute
Begin by locating the statute in the U.S. Code through Westlaw, LexisNexis, or a free source like Cornell's LII
Use the annotations and references to trace the statute back to its enacting session law
Search for committee reports, hearings, and debates related to the bill using databases like ProQuest Congressional or HeinOnline
Consult secondary sources, such as treatises and law review articles, that discuss the statute's legislative history and intent
Scenario 4: A paralegal updating research on a tort law issue for a senior attorney
Review the attorney's previous research and identify key cases and statutes
Use citators (Shepard's or KeyCite) to check for new cases that have cited or discussed the key authorities
Conduct additional searches using Boolean operators and filters to find any recent developments in the relevant jurisdiction
Organize the updated research in a clear, concise memo or report, with proper citations to electronic sources
