How do you keep track of all the storylines and characters that you have woven into the series? Do you have a system of reference or is it all stored in your head?
The storylines are all in my head, except that when I begin a book I do sit down at the computer and ramble about a bit to figure out exactly how I intend to fit various things together. For the characters—and the cultures, nations, organizations and a great deal else—I have files on my computer. For example, there are two files on Aes Sedai. One has things like the history of the White Tower, its laws and rules, the customs and group attitudes of Aes Sedai as a whole and among the different Ajahs, details of organization for the various Ajahs, how the Hall of the Tower works and how Sitters are chosen in the different Ajahs, how women come to enter the Tower, how they are trained.... In fact, just about everything I can think of that might be useful to know about the White Tower. The other Aes Sedai file lists every sister, Accepted and novice who has been mentioned in the books, along with 'civilian' personnel of the Tower, and gives both every piece of information about those people that has been in the books and information that has not yet been used. And might not. In part, I put it all together to round out the individuals, give them flesh. I am very glad to have an LS120 drive on my computer, because each of those files is now too large for the smaller 1.44 floppy.
