There are a few different guys who maintain maps. This guy, nexus, has the most popular one. It's not my preferred map, as it's a bit wrong in the second level, and the colours are annoying underground. I use another, which was orignally about A1, which i cut down to carrying size.

Note, these maps are *only* for the GRS, or the tunnel network under the14th district of paris. There are more under the 13th, 15th, and 16th - and pretty much every single area and suburb of paris has series of networks - not as extensive as the GRS, but in a lot of cases, a hell of a lot more interesting.
