How to cite Kindle books/ebooks when no fixed page numbers are available? I got the following info from the Chicago-Style Citation Quick Guide website in relation to citing Kindle books or ebooks.


  If no fixed page numbers are available, you can include a section title or a chapter or other number.


I am wondering is there a preferred method of citing in this case? 

I am history Mlitt student and have only recently started to use a kindle for research purposes. At the moment I use the loc (location) reference that is produced by the kindle in the notes text file you can download from it, that shows all your highlights/bookmarks, but I am confused as to the proper citation method as my supervisor queried if this was the standard way of citing a kindle. I have a copy of my history department style-sheet but it makes no reference to kindle editions.
According to the APA blog, the location number is actually a bad idea because it has limited retrievability. The blog also mentions that since Kindle's third generation, e-books have started to have real page numbers, you may try looking into that.

Another post on apastyle.org suggests that for materials that are not paginated, consider citing chapter number or chapter heading plus paragraph numbers.
