The law is constantly changing and it can be difficult to keep up with what's new in your area. There are several web sites (free and paid) that offer current awareness services, alerting subscribers to new cases, new bills and legislation, and new commentary in law.
A simple option is to subscribe to a web site's RSS feed or e-mail alert. Many web sites and blogs have news feeds that send new information to your RSS reader or e-mail address. These can usually be found by searching the name of the web page and "RSS".
