I notice other book series show the number like so: The Book Title (XYZ Series #4). The title "The Book Title" would have been typed into the blank for title, and the series name "XYZ Series" into the blank for series name. And then, presumably, the 4 is the number entered into the space for Volume Number. But that number doesn't show up on Amazon. So do you guys type in the #4 as part of the series name? And if so, doesn't that say to Amazon's computer brain that the book is a different series? Because XYZ Series 1 is not the same Series as XYZ Series 3, etc. That's why they have the volume blank, isn't it? And yet, no numbers are appearing. Am I just over thinking this?
