Actually... no, they are not all the same map. The second link - to a pdf rather than a website - is an outdated version. This is a good example of why we have always requested people to link to a website and not directly to a pdf... so they are sure to get the most updated version. The map team has 3 main websites that host the map and we always update those sites with the most recent version when they are made.

(Note: a mini update was done about 3 months ago with a few changes such as For Real and Merrils 3 changing names)
