How to cite self-published work

I have a book that is self-published (not by me). I want to enter it into EndNote x3 but I can’t figure out under what category should the book come under since there is no “Self-Published” category. It would seem that the “Unpublished” category is wrong too because the book is printed and available in libraries and can even be bought.

Thanks!

What fields are missing from the book ref type?  I would put “self-published” in the Publisher and if a city or other location is know, put that in too, otherwise leave it blank?
