As many of us recall from our civics lessons in school, the United States is a common law country. That means when judges issue opinions in legal cases, they often establish precedents that will guide the rulings of other judges in similar cases and jurisdictions. Over time, these legal opinions build, refine and clarify the laws that govern our land. For average citizens, however, it can be difficult to find or even read these landmark opinions. We think that's a problem: Laws that you don't know about, you can't follow — or make effective arguments to change.

Starting today, we're enabling people everywhere to find and read full text legal opinions from U.S. federal and state district, appellate and supreme courts using Google Scholar. You can find these opinions by searching for cases (like Planned Parenthood v. Casey), or by topics (like desegregation) or other queries that you are interested in. For example, go to Google Scholar, click on the "Legal opinions and journals" radio button, and try the query separate but equal. Your search results will include links to cases familiar to many of us in the U.S. such as Plessy v. Ferguson and Brown v. Board of Education, which explore the acceptablity of "separate but equal" facilities for citizens at two different points in the history of the U.S. But your results will also include opinions from cases that you might be less familiar with, but which have played an important role.

We would like to take this opportunity to acknowledge the work of several pioneers, who have worked on making it possible for an average citizen to educate herself about the laws of the land: Tom Bruce (Cornell LII), Jerry Dupont (LLMC), Graham Greenleaf and Andrew Mowbray (AustLII), Carl Malamud (Public.Resource.Org), Daniel Poulin (LexUM), Tim Stanley (Justia), Joe Ury (BAILII), Tim Wu (AltLaw) and many others. It is an honor to follow in their footsteps. We would also like to acknowledge the judges who have built this cathedral of justice brick by brick and have tried to make it accessible to the rest of us. We hope Google Scholar will help all of us stand on the shoulders of these giants.
