These are Route 66 travel guides and books that I suggest and have personally reviewed. Having a guide is essential to getting the most of your Rt 66 adventure. Combine these guides with my map of early alignments and you can explore the original roads taken by Route 66. You can support this website and these authors by purchasing through the links. I get a very small fee from Amazon that helps with the expense of running this site and it does not add to your cost. Thanks!!
