I went round and round with them on what constitutes a links. Not sure what ended up in the book, but my take has always been that you need to focus on the origin of the word "links".
A seaside golf course constructed on a natural sandy landscape that has been shaped by the wind and receding tides. From the Old English “lincas”, meaning the plural of a ridge, a Scottish term to mean the undulating sandy ground near a shore.
From my conversations it appeared that they were tending to including such attributes as wind and the style of a course, not just the geography. Wind certainly has a place, but it alone does not make for "links" as you must have the tidal effect. At least that is my position.
