(QR Code for the Lone Wolf Librarian blog)
There hasn’t been much discussion of libraries and QR codes lately but today there is a good post from the Emily Brown, Outreach Librarian at Northeastern State University, Muskogee campus, on her blog brownez@thelibrary titled Tuesday Two.Oh! Tools for Advertising which is excerpted here:
“…We will actually be taking a look at two sites today, both of which are easy to use and easy to navigate. So, get out those cell phones and let’s start talking QR Codes…
I was introduced to this technology by an innovative librarian at the University of Central Oklahoma, Amanda Lemon. Amanda and Jason Cimock (also of UCO) presented at this years COIL workshop, unCOILed. They spoke about mobile phones in the classroom, and their presentation can be found here. Part of the presentation focused on todays tool, QR Codes. It’s a very interesting presentation, and if you have time, I suggest that you take a look.
On to the tools! The first tool we’ll be taking a look at is Mircosoft Tag Beta…
There are a lot of potential uses for this technology.
To be fair, there are a lot of code creations sites out there. Spend a little time on Google and you’ll find a site that fits your needs. With that in mind, let’s look at another code creation option. Q-Lytics…”
Of course, Europeans seem to be more committed to QR Codes 
as this video will attest:
Hi Lone Wolf
If you use a beetagg http://www.beetagg.com you also can add a logo or a photo.
This adds value to the QR-tag.
