Just got the numbers from the Accountancy Wing of the Zompist Fortressplex. Since the beginning of time I’ve sold just under 13,000 books in all formats. Print and Kindle run about even.
Nearly half that— 6351 books— is the Language Construction Kit. That’s pretty respectable sales for a book; Amazon tells me it’s #39,836 on their print books ranking (#39 in linguistics). This year it’s being used as a textbook in two different university courses. (Not the first time; last year I visited a class at Purdue that was using it, which was a lot of fun.)
The news if you’re hoping to sell your sf/fantasy novel is: keep the day job. Babblers, along with its supplementary volumes, has sold 71 copies. That’s actually better than Against Peace and Freedom did in its first four months (42 copies). APAF still hasn’t reached the 200 sales where I said I’d create a conlang for it. (It will probably be Hanying, by the way.) I’m not complaining– doing Babblers this year was a labor of love, and the people who’ve read my novels tend to like them a lot– but the next book will definitely be non-fiction.
What will that be? Well, might as well start building interest: I’ve been working on a book about China and Chinese, tentatively called China for Conlangers. I think most conworlders know enough about European history to create classical and medieval worlds, but don’t know where to start with China, so the book will tell you what you need to know about Chinese history, religion, literature, art, technology, and architecture, as well as the Chinese language and writing system. As with all of my conworlding books, it’s also a sneaky way to impart actual information. I haven’t thought of a better title, though.
(I’m also tempted to write an English-language grammar of Quechua, since such a thing isn’t readily available. Feel free to lobby for this…)
