Erm, yeah, I've got a lot of these. I was surprised to discover I had 17,789 words of deleted stuff for Book 1. Most of this amounts to over-explanation of certain things and telling instead of showing. In contrast, I've only taken one 250-word scene out of Book 2. But I'm yet to get into serious edits for that. I'm sure it'll grow exponentially.
I find these indispensable, as I always tend to lose track of what day it is. So far I've only got one for Book 1, which only takes place over a couple of weeks, but it's a busy couple of weeks. It's important to know what happens when.
- CP Notes
It's essential to keep all these in one folder so I can compare and contrast what different people thought of each thing. That helps me weigh up what changes to make.
- Book 2 Notes
Not CP notes, but a list of various things to be checked and verified, often in relation to Book 1. It's surprisingly easy to have things that contradict each other in a series so I need to make sure everything adds up seamlessly.
- Book 3 Plan
I don't normally do a lot of planning, but for the final book in the trilogy it seemed a pretty good idea, so I wouldn't veer off down an irrelevant track. In a lot of ways this is the most important book as it has to tie everything together. Everything's still open to change as the story develops, though.
- Book 1 Marketing Plan
I started this a while back, as I originally planned to release Book 1 earlier, but decided to have the rest of the series written first. It's a handy thing to keep a hold of, adding or amending certain items as trends change.
I'm sure lots of you have similar things for your books and probably much more - Pinterest boards, character profiles, storyboards, wall charts. (If I had my own office, the walls would be covered with WIP-related stuff!) I'd be interested to hear all about it.
