I picked up the Thomas Guide at Costco here in Sac about a month-and-a-half ago. It was the 2006 version for Sac and Solono Counties. Id had the CD in the back in a clear plastic sleeve. Wall maps are cool for your radio shack, but If you can spare a computer, it's cool to have the electronic version of the Thomas Guide so you can enter the address directly and just see the location. If your machine is connected to the Internet, you'll be able to click on locations in the map and see web information on the site if there is any available. I like the Emap because you can zoom in and out as needed.
