We've had lengthy discussions of locations and the threads are around here somewhere but in a nutshell...they have no relation to pages in a paper book. They are unique to the ebook and tell you where you are. The good thing is that locations don't change even if you change the font size. So location 1000 at font size 1 is the same as location 1000 at font size 6. So you can reference where you are, or tell someone else about a location, and you will be accurate.
