Case Notifier Services
This is probably old news, but you should be aware of two useful notifier systems that give you a heads up about recent cases before the state and US Supreme Court. For Wisconsin cases, take a look at Caselaw Express, a service from the State Bar.
The Supreme Court Collection at the Legal Information Institute previews upcoming US Supreme Court cases, as well as recently decided cases, through its liibulletin-cert page. For example, I learned that the Booker case on Federal Sentencing Guidelines had been decided through a notification I received.
