It's quite an achievement.

I was once interested in publishing a SF anthology. Formatting and editing was nbd -- I was going to use Amazon's KDP software package for most of it, which can take a .docx and output an ebook in 5 minutes. I've done it before for non-anthology books I've published, and it couldn't be easier, though I understand why people might avoid Amazon in this day and age.

The real trouble was getting the rights to all of the different stories! Though everybody I was able to get in touch with was great -- in particular, Peter Watts, Alan Dean Foster, David Moles, and Walter Jon Williams -- many authors were totally impossible to reach! I ended up scrapping the idea after a few stories I was intent on collecting in the anthology were unobtainable. (And this after I had already paid an initial sum to many of the authors.) Finding alternates and embarking on more contract negotiations just seemed like too much work.

Anyway, I bought your anthology, will review when I'm done reading, and sincerely respect the hard work that went into it!

Thanks, you're completely correct, rights acquisition was the most difficult part!

The absolute hardest story in the anthology to get rights for was "Stars Don't Dream" by Chi Hui. It's a translation of a story that won an award in China, but Chi Hui doesn't speak English, and her contact info was extremely hard to obtain (I had to get help from the editor of Clarkesworld Magazine). We did the entire contract discussion via a combination of Google Translate and my very weak Mandarin I learned in college.

(I'm a huge Peter Watts fan, btw)
