What's in it

72,627 documents we prepared ourselves, plus federal and state case law. Each collection is searched on its own, so a tax question doesn't return ethics opinions.

Published and unpublished opinions, with citation analysis that shows who has cited a case and how deeply.

Judge Analytics

3,767 judges across 117 courts

How individual federal judges actually rule, drawn from their own signed orders rather than from reputation.

The Law Library collection picker, showing all nine collections
One library, nine collections

Pick the kind of authority, then search

A single box searching everything sounds better than it reads. Ask about a fee-sharing arrangement and you don't want OSHA decisions in the results. So you choose the collection first, and every filter, snippet and label after that is the right one for that kind of document.

  • Each collection has its own filters: state, court, bar, year, topic
  • Filters only offer states the collection actually covers
  • Recent searches are kept, and can be cleared one at a time
  • Nothing to install and nothing to configure. It's already in your sidebar
AG opinion search results, each showing the question and the answer
Plain English first

The answer before the document

Every AG opinion, ethics opinion, tax ruling and IRS determination has been read and rewritten as the question it answers and the answer it gives. You can tell from the results list whether a document is worth opening, which is most of the work.

  • A real question as the title, not a docket number
  • The holding in the first two lines, in plain English
  • The matching text from the original, highlighted
  • Citation, issuing body and date on every result
What a result looks like:

"Can a North Dakota sheriff's office refuse to release inmate disciplinary records under an open records request?" No violation. The AG concluded the office properly withheld institutional discipline and protective management records…

Judge Analytics results showing how federal judges rule on qualified immunity
Judge Analytics

How your judge actually rules

Search by name to read a judge's profile, or search by the issue to find every judge whose record speaks to it. The profiles are built from the judges' own signed orders, not from anecdote or from a survey of lawyers who lost.

  • Search a name, or search "qualified immunity" and see who has ruled on it
  • Every profile says how many signed rulings it was drawn from
  • Court, appointing president and status on each result
  • Results say plainly when a judge is only mentioned, not matched by name
A 50-state survey question answered for Pennsylvania, Missouri, New Jersey and Arizona
50-State Surveys

The same question, every state

The research that used to mean fifty tabs and a spreadsheet. One question, like how much home equity a judgment can't reach or how long a mechanic's lien lasts, answered for every state. Each answer carries the date it was last checked against its own source.

  • Dozens of topics, each answered for all 50 states
  • Every answer names its statute and the date it was verified
  • Says so when a state has no rule, instead of leaving a blank
  • Compare states side by side, or filter to the one you need
