When writing, we all have different ways of organizing our thoughts and ideas. Below is a fun little piece of history from J.K. Rowling’s Harry Potter and the Order of the Phoenix. This page (you can click to view it in a larger format) covers chapters 13 through 24.
You can find more details at Endpaper but I’ll quote just a little from there:
Part of this page’s charm, of course, is it’s roughness. It’s handwritten in cursive on loose leaf paper; the column lines weren’t done with a ruler; many words and paragraphs are scratched out or re-written. She may be J.K. Rowling, brilliant best-selling author of the Harry Potter series, but a document like this can be created by anyone…
…Note that some columns have nothing written in them and others vary from having complex to simple details. (The initial “Order of the Phoenix” columns have very simple details: Chapter 13 is called “Recruiting”, chapter 14 says “first meeting”; chapter 20, on the other hand, just says “big meeting”.)
