I am part of a monthly critique group, as well as a more sporadic workshop, so I need a place to write down the feedback I receive on my work, as well as any ideas I have for edits to a piece. The Critique and Edit Notes notebook will be the home for that info.
Publication information goes in the next one. This is where I'll keep track of contract terms (Do I retain audio rights to this story or does the publisher? When does the exclusive printing period end? Is it a flat rate payment or are their royalties to track?). This way I won't have to go combing through contract files every time I want to reprint a piece.
In the next notebook, I'll record bits of wisdom about the craft of writing. When I attend panels or author talks, I like to write down anything educational or interesting, or notes about what particular editors are looking for in work submitted to them.
In the last notebook, I'll keep track of my own gigs--when I lead workshops or teach classes, do readings, speak on panels, do interviews, or appear on podcasts. I haven't always been good at tracking that, and then a friend mentioned how important that info is for a potential CV if I ever want to get a teaching job or archive my work. This will give me a good way to plan for and track all those appearances.
