4th Circuit Update Tools

There are two services on the net (that I know about) which alert you via email when new 4th Circuit opinions are published. Both services are free. One option is on the 4th Circuit's own site. From this page, you can register to receive summaries of newly published 4th Circuit cases. Findlaw provides a similar service. You can sign up on this page by checking the appropriate box. If anyone knows anything about the differences between these two services please feel free to comment.
