::Okay, and for now I'm going to just go with the later edition of Kinkade's book, ie. cite ref. #[15] twice and get rid of ref #[8]. 
 ::As far as the last tag, WP:PRIMARY is the policy that applies, and that says:: Unless restricted by another policy, primary sources that have been reliably published may be used in Wikipedia, but only with care, because it is easy to misuse them. Any interpretation of primary source material requires a reliable secondary source for that interpretation. A primary source may only be used on Wikipedia to make straightforward, descriptive statements that any educated person, with access to the source but without specialist knowledge, will be able to verify are supported by the source. For example, an article about a novel may cite passages to describe the plot, but any interpretation needs a secondary source. Do not make analytic, synthetic, interpretive, or evaluative claims about material found in a primary source. Do not base articles entirely on primary sources. Do not add unsourced material from your personal experience, because that would make Wikipedia a primary source of that material. Use extra caution when handling primary sources about living people; see WP:BLPPRIMARY, which is policy.So, it's okay to have some primary, "self-published" sources, but they have to be used carefully and sparingly.  Kinkade was a founding member, right?, so that would make her books primary sources, too.  I have not looked too carefully at exactly how they are being used here.  If I did, I'm guessing I'd probably have to remove a lot of stuff, so it's either that or leave the tag up for now... ;)
