If you want special elements in your book, or if you have images or charts or illustrations, please inform your project manager early on. It’s common for our authors to include design elements like these, but if they’re introduced too late in the process, it slows us down and creates more work for our designers. There’s information in the Author Handbook about sizing and how we want images and illustrations delivered. Also, some authors want to hire cartographers or other specialists. If you need a resource, ask us!
