To use a public law library, walk into the one at or near your county courthouse, tell the librarian what legal question you’re working on, start with a secondary source that explains the area of law, then pull the specific statutes and cases it cites and check each one in a citator before you rely on it. You don’t need a card, a lawyer, or an appointment. The collection and the databases are free to the public, and the staff are trained to help you find things, though not to tell you what to do.
Finding the Library and Planning Your Visit
Most public law libraries sit inside a courthouse or in a building next to one, and they’re funded by the county or the court system. Search “[your county] law library” and the right result usually comes up first. If the county site is hard to navigate, the American Association of Law Libraries keeps a directory of member libraries by state and city.1American Association of Law Libraries. Member Libraries Local bar association websites are another reliable starting point.
Hours generally track the courthouse: roughly 8:00 a.m. to 5:00 p.m. on weekdays, sometimes with a lunch closure or a short Friday.2University of Cincinnati Libraries. Non-Law School Patron Guide to Law Library Access and Use Policies Call before you drive out. If the library is inside a courthouse, you’ll go through security on the way in, so leave anything prohibited in your car and bring a photo ID. Laptops and phones are almost always fine inside the library itself.
Before you leave the house, write down what you already know: dates, names of the parties, any case number, the court where your matter is pending, and the specific question you need answered. Bring copies of anything you’ve already been served with or filed. A specific question gets you specific help; a vague one gets you a shrug and a shelf number.
What You’ll Actually Use Inside
Legal materials fall into two buckets, and knowing which is which is the single biggest thing that makes research productive.
Primary sources are the law itself: statutes passed by legislatures, regulations issued by agencies, and opinions written by courts.3Stanford Law School. Free and Low-Cost Legal Research: U.S. Secondary and Primary Sources – Section: What are legal primary sources? In print you’ll find them in bound state and federal codes, the Code of Federal Regulations, and case reporters that collect appellate decisions by jurisdiction.4Georgetown University Library. Primary Sources in U.S. Law – Section: Understanding Primary Legal Sources These are what a judge actually looks at, and any argument you plan to make has to trace back to one of them.
Secondary sources explain the law. They’re where you should start, because they translate dense statutory language and point you to the exact statutes and cases you need. Two big national legal encyclopedias, Corpus Juris Secundum and American Jurisprudence, cover almost every topic at a general level.5Georgetown Law Library. Legal Encyclopedias – Secondary Sources Research Guide For a single subject in depth, ask for a treatise on that area, whether it’s landlord-tenant, family law, or employment discrimination.
The other reason to show up in person is the database terminals. Individual subscriptions to Westlaw and LexisNexis run hundreds of dollars a month, and many public law libraries offer on-site access at no charge. You can run a keyword search across millions of cases, statutes, and secondary sources in seconds. Ask staff about any limits on printing or session length when you sit down. Most libraries also keep standardized court forms for common civil matters like small claims, divorce, name changes, and restraining orders; the library copies are sometimes annotated with filing tips the court’s website leaves out.
What the Librarian Will and Won’t Do
Law librarians are reference professionals, and a good one will save you hours. They’ll show you how the collection is organized, suggest a secondary source that covers your issue, demonstrate the databases, teach you how to read a citation, and pull the right volume of the code off the shelf.
What they cannot do is tell you what the law means for your case. Every state prohibits the unauthorized practice of law, and giving legal advice without a license falls inside that prohibition.6William and Mary Law School. Library Staff, Legal Advice, and the Unauthorized Practice of Law So a librarian can show you where the divorce statutes live and hand you the form packet, but can’t tell you which form to file, help you fill it out, or say whether a statute helps or hurts your position.7University of Iowa Law Library. Law Library Research Guide – Section: Legal Information vs. Legal Advice
Frame your questions around finding materials, not solving your problem. “Where would I find the statute on child support guidelines?” gets you much further than “How much will I owe?”
A Research Sequence That Actually Works
Start With a Secondary Source
Resist the urge to open the statute book first. Pick up a legal encyclopedia entry or a treatise on your topic and read it. The whole point of these books is to explain the area in plain English and cite the specific statutes and cases that govern it. A couple of hours with a good treatise often accomplishes more than a full day of unfocused searching in the code.
Then Pull the Primary Law
Once the secondary source has pointed you to specific statutes, regulations, or cases, pull them and read them carefully. Look at the definitions section of any statute you’re relying on, because legal terms often mean something narrower or broader than they do in everyday speech. When you’re reading a court opinion, focus on the facts and the holding rather than the procedural history. Take detailed notes with full citations, including volume and page numbers, because you’ll need exact citations if you file anything.
Run Every Authority Through a Citator
This is the step non-lawyers skip, and skipping it can sink an otherwise solid argument. A citator tells you whether a case or statute is still good law.8Pritzker Legal Research Center. Determining Whether Cases Are Still Good Law – Section: Citators Statutes get amended. Cases get overturned. Citing a repealed statute or a reversed case is worse than citing nothing. The two main citators are KeyCite on Westlaw and Shepard’s on Lexis, both available on the library’s terminals, and they use color-coded flags to signal negative treatment at a glance.9University of Washington Law Library. Citators – Using Lexis, Westlaw and Bloomberg Law – Section: What does it mean when people ask if a case or statute is still good law? A red flag or stop sign means the authority has been seriously undermined; a yellow flag means there’s some negative treatment worth reading. Run every case and statute you plan to rely on before you leave.
Free Online Alternatives
Some research doesn’t require a trip. Several free sites cover a lot of ground for straightforward questions.
- Google Scholar covers U.S. Supreme Court, federal appellate and district, and state appellate opinions. Select “Case law” and narrow by jurisdiction.10Library of Congress. Free Case Law – Google Scholar
- State legislature websites publish current statutory codes for free; search “[your state] statutes” or “[your state] revised code.”
- Cornell’s Legal Information Institute has the U.S. Code, the Code of Federal Regulations, and Supreme Court opinions in a clean, searchable format.
- The Office of the Law Revision Counsel at uscode.house.gov keeps the most current version of the U.S. Code.
- CourtListener and Justia offer free federal and state case law with basic search.
Where the free tools fall short is verification. None of them run a real citator, so you can find a case but can’t easily confirm it’s still valid. Google Scholar has a “Cited by” feature that shows later cases referencing yours, which is better than nothing but not a substitute.10Library of Congress. Free Case Law – Google Scholar For quick statutory lookups, free sites work fine. For anything you plan to hand to a judge, go run your authorities through KeyCite or Shepard’s at the library.
When Research Isn’t Enough
A law library gives you information. It doesn’t give you a lawyer, and information isn’t always what the situation needs. If real money, custody, or your liberty is on the line, or you’ve done the research and still aren’t sure what to do, get an actual attorney.
Legal aid organizations provide free representation to people who meet income eligibility, typically at or below 125% to 200% of the federal poverty level. Search “legal aid” plus your state or county. State and local bar associations run referral services that connect you with attorneys for a reduced-cost initial consultation. Some jurisdictions also operate court-based self-help centers, which are separate from the law library; staff there are often authorized to help you fill out forms and explain court procedures, though they still can’t represent you or advise strategy.
If your matter is simple and you plan to handle it yourself, take your finished research to a brief paid consultation with an attorney and have them confirm you haven’t missed something critical. An hour of attorney time reviewing a solid file costs far less than hiring someone to start from zero.
