I could swear I posted this information before, but as the question keeps arising, there is no harm to posting it again. It’s also a chance to plug both the University of Washington Law Library and the King County Law Library web pages. Some of the links are naturally Washington State-based, but not all. Between them they have some of the best, most practical, and sometimes even fun legal research information web pages. Thanks for sharing!
Here’s the UW Low-Cost Legal Research Services on the Web guide.
