FYI, the original run of the DC Who's Who also lists the different cities of Atlantis. It also goes on to mention Travis's Skartaris offshoot of Atlantis that migrated beneath the Earth where Mike Grell's Warlord stories took place. DC firmly embraced the idea that Atlantis had at least several cities that went different routes thus explaining the different takes on Atlantis in the DCU. They're all true only they were showing a different city of the Atlantean nation. It's like showing NYC as representing the USA for one tale and Chicago for another.
