This is readable by any smart phone with a QR app.

I also like it as art. QR codes require a reader download to your smart phone, for example Kaywa.

Library use for research would include directing a patron with a smartphone to an informational website or related database from a QR code in the stacks. 

Federal case files that are closed are transferred from the Courts to the National Archive. From the 1960s onwards, regional archives store transcripts, pleadings, exhibits, dockets, and any other proceedings from the Federal Courts of Appeal, Bankruptcy Court, Civil and Criminal Courts.

Arizona Federal case files are stored at the National Archive center in Riverside, CA. For a fee anything can be obtained and delivered to the legal researcher. You can also gumshoe your way to Riverside to access the case archive in person. This same system is administered by the National Archives nationally so closed case files from any jurisdiction can be accessed.

Here is an example of legal research not typically conducted online, but some of these documents are being scanned and added to databases like Westlaw.  

Holistic Law

Think that legal practice must be confrontational?

Alternative approaches include holistic law, a tradition that teaches lawyers to be helpers and healers. There is an International Association with focus on prevention and collaboration rather than confrontation. Holistic law and closely related themes such as therapeutic justice and restorative justice are discussed by Wright in the book Lawyers as Peacemakers (2010).  

For more information, the book Lawyers as Peacemakers is in the PSL Library.
