One of my roles at Sydney University Press is editing books, and while I was at Touchpress I had an opportunity to learn more about editing apps. Many insights came from speaking with Fiona Barclay and Mari Volkosh, knowledgeable editors who have worked on apps across various subject areas from science to archaeology to literature. I even helped with copyediting the content for one of their upcoming apps, which showed me how working on apps differs from editing of books.
The most important thing, I have realised, is that an app design is driven by visual and interactive elements, rather than text. Basically, apps don’t aim to replicate books and instead they focus on interactivity and providing an experience that uses different modes of communication. Having said that, there is still a place for editorial control over the overall structure of the content, the style of writing and its suitability, but written content plays a secondary role in an app.
