It is a very new release, fag end of last year. I suppose it’s all being rolled out and takes some time to get everything on Amazon.
He has Columbia as a publisher so I would guess they’ll eventually make it available worldwide.
It's a nice little book, lots of interesting stories. It's published by Columbia Global Reports which is a series of small topical books. It is not Columbia University Press and their distribution is spotty because I think they mostly sell direct. I find them interesting enough that I have an annual subscription so they send me the physical books in the mail. https://globalreports.columbia.edu/books/the-web-beneath-the-waves I'm in the U.S. and Amazon says I can't get the Kindle edition either. There's a note on the Amazon page saying "Customers reported quality issues in this eBook. This eBook has: Typos, Poor Formatting . The publisher has been notified to correct these issues." I suspect they've withdrawn the ebook until they can fix it. The paper book is fine. R's, John
