For a first-year law student, opening Westlaw or LexisNexis for the first time can feel like being handed the keys to a library where every book is written in code. These platforms are the dual engines of legal research, and while they are incredibly powerful, they can be overwhelming if you treat them like a standard search engine.
Efficiency in legal research isn’t about finding any case; it’s about finding the right case as quickly as possible. Here is how to navigate these platforms like a pro.
1. Master Terms and Connectors (Boolean Searching)
While both platforms have improved their “Natural Language” (Google-style) search, the most efficient researchers use Terms and Connectors. This allows you to be precise about how your keywords relate to one another.
- Quotation Marks (” “): Search for exact phrases (e.g., “duty of care”).
- The Slash (/p or /s): Find terms within the same paragraph (/p) or the same sentence (/s). This is vital because it ensures the court is discussing your keywords in the same context.
- The Asterisk (*): A root expander. Searching negligen* will find negligence, negligent, and negligently.
2. Use the “GPS” of Legal Research
Both platforms have proprietary systems that categorize every legal headnote into a massive hierarchy.
- Westlaw’s Key Number System: If you find one perfect case, look at the “Key Numbers” in the headnotes. Clicking one will lead you to every other case in that jurisdiction that discussed that exact narrow point of law.
- LexisNexis Topics: Similar to Key Numbers, these allow you to browse by legal subject matter, ensuring you don’t miss relevant statutes or secondary sources.
3. Check Your “Vibe” (Validation Tools)
Before you cite a case in a memo, you must ensure it is still “good law.”
- KeyCite (Westlaw) & Shepard’s (Lexis): Look for the signal flags. A red flag typically means the case has been reversed or overruled on at least one point. A yellow flag warns of negative treatment, such as a later court distinguishing its facts from yours.
- Practical Tip: Don’t automatically discard a yellow-flagged case. Read the “Citing Decisions” to see why the warning exists; the case may still be valid for the specific point of law you are researching.
4. Start with Secondary Sources
One of the biggest 1L mistakes is diving straight into case law. Instead, start with Secondary Sources like Restatements, Treatises, or Law Review articles. These resources provide a “bird’s-eye view” of the law, summarize the landmark cases, and give you the exact vocabulary you need for more effective primary searches.
5. Leverage Folders and History
Legal research is rarely linear. Use the “Folder” system to keep your research for Torts separate from Civil Procedure. Both platforms also keep a “History” log of your searches. If you found a great case three hours ago and forgot to save it, check your history rather than trying to recreate the search from scratch.
Beyond Law School
As a student, your access to these tools is focused on academic mastery. However, once you enter the professional world, these platforms transform into comprehensive business hubs. Practicing lawyers often utilize Westlaw and LexisNexis for Business Resources, including litigation analytics (to see how a specific judge usually rules), Practical Guidance (templates and checklists for drafting), and even M&A benchmarking tools.
Final Advice: Get Certified
Both Westlaw and LexisNexis offer student certification programs. These are free, take a few hours to complete, and look excellent on a resume. They force you to use features you might otherwise ignore, making you a much faster researcher for your summer internships.
Because every legal research problem is unique and platform features update frequently, you should always consult with your law librarian or a qualified research instructor to stay current on the latest tools.
