I want to make some updates to a [free] ebook I wrote several years ago when Rice University was still running their Connexions service open to the world
I keep the most recent edition of that ebook as a pdf on my blog
What is the current "great ebook creation" toolset that all the Cool Kids™ are running? Is it to refactor it into something like Obsidian notes, connecting them, and exporting to pdf? Is it a 'classic' word processor like Apple Pages or Microsoft Word or Google Docs?
Beyond merely updating/expanding what I wrote previously, I also have a few other ebooks I want to compile - and would like to not learn more than one tool to do this.
