I will second what has been said about the anthology.
I have published e-books of musical scores. I transformed the manuscripts into images to ensure that the music was displayed on the page as I wished it to be. I expect that poetry requires similar treatment. In some cases, the introduction was written in page format, while the music was displayed in landscape format. In a physical book, a transition between landscape and regular format would be awkward because of the spine of the book. In an e-book there is no such problem.
