You can install a free app for Chrome which allow you to look up legal citations quickly. BlueLine Fetch is available here:
After it is installed when you select a legal citation in your chrome browser you can right click and select the option for 'Blue Line Fetch Legal Citations'.
If you have the 'Quick Fetch' option selected, Blue Line will automatically open the cited case or statute, without any further action required.
The BlueLine Fetch app works with Westlaw, Lexis, and Google Scholar.
