I'm currently reading my way through the Dresden Files novels as a background to playing the game. (Related: Should I read the Dresden Files fiction before I get the RPG?). I now want to know how many of these books feed directly into the rpg core books, and would so be "spoiled" by reading the rpg books if I moved on to them too soon.
So, my question is, from which Dresden Files novels do "Your World" and "Our Story" pull materials?
What I've found out so far:
The Wikipedia article on the Dresden Files rpg does address this question, but what it says is confusing to me:
Evil Hat brought in Genevieve Cogman to do the research on the six Dresden Files that had been written by that time in 2004, as well as the ten more that were written by the time Evil Hat decided to put a cap on what the game would cover several years later.
I find this confusing, as to date (June 2015) only 15 Dresden Files novels have been released, so there were not 16 novels in 2010 when dfrpg was published.
The Wikipedia article also makes reference to the book "Designers & Dragons", but I have searched that book for all references to Dresden Files, and not found an answer to my question.
Someone with a similar problem to me posted a question on the rpg net forums but I find the answers there unsatisfactory, as they refer to "the books" in an undifferentiated way.
