Many of these maps are from the Japanese EQ site: Questor of Norrath (who, apart from the bizarre and inexplicable "Plane of Sika" prank, is a very reliable source...)
Others are from various places around the web. I try to give credit where it is not specifically written on the map itself.
I intend to add updated and annotated versions of these maps as time allows.

Others are from various places around the web. Also check out AllaKazam's site, EQ'Lizer and the amazing font of cartographic knowledge that is: EQMaps.com.
