Here are details of a book that members may find interesting:
LOST ISLANDS - The story of islands that have vanished from nautical charts.
By Henry Stommel
Published by University of British Colombia Press, Vancouver
It does exactly what it says on the cover! It is the story of islands that are known to have existed but have now disappeared from the charts, islands that never existed but are still on the charts, islands that are not where the charts say they are etc...
An interesting book for those who navigate, and those like me who do not venture from the sight of land.
