Do You Read the Packet Wrapper?

Court files are often kept in bundles. That outer wrapping will have key elements of the case and other filing information. It's also possible that there are clues on that outer wrapper. There may notes, names, or other seemingly random pieces of information on these jackets. 

And sometimes when combined with other information these seemingly random pieces of information are significant. Other times, they provide "out of the blue" clues that help to break down that brick wall.

Do you always read the packet wrapper?
