The Dresden PDFs - or at least the pre-release ones that I got when I pre-ordered - are easy to copy from.
Since we had some player who were behind in the books I made a "spoiler friendly" version of our world by opening the pdf, hitting control A, then pasting into Word. That gave me a huge text file.
Then I did a pair of search and replaces, replacing the letters that boarder every page with nothing and the file wasn't so huge. Then I went through deleting the hard returns. The hardest part? The sidebars. All of those comments by Bob, Harry, and Billy were basically at random spots on those pages. Even when I moved them around so they made sense the underlines were missing so it wasn't clear what they were commenting on.
But it can be done - and when you're finished you have a text file that has all the rules in it.
