Some context for HN: This is a self-published book, which is nonstandard in my field. Usually you work with large academic publishing groups. The choice of self-publishing is an unknown process to most academics in science and engineering. It afforded me an opportunity to learn more about publishing, bookmaking, marketing, and distribution. Self-publishing allows the author to retain creative control on how the book is made, presented, and shared.
I know HN is interested in academic publishing policies, copyright, DRM, etc. This project presents an alternative for researchers to share knowledge.
