Whenever I read a book I almost always see three dots at the bottom of a page one time in the book, sometimes more than that. Can anyone tell me what they are for? Do they have any significance?

Are they a regular number of pages apart give or take one?
Something to do with the printing/binding/production process perhaps?

You know how there's usually an extra carriage return when there's a scene change? The ellipses you're talking about probably do the same thing, since it's clearer than leaving an extra space at the bottom of the page.

What Aghama said. A lot of books divide chapters into manageable sections separates by spaces so people have a good stopping point without having to read the whole thing through.
Imagine this post were a book, and I am not leaving a space between my paragraphs.

But then they do leave a space. Sometimes that space falls at the end or beginning of a page. The printers will use

***

to make sure you as a reader know there's supposed to be a space there. But you can't tell there's a space because it's the end of the page, hence the need for the symbol.

I hope I overexplained that enough without talking in circles
