How did Yuval self-publish his book?

Yuval Noah Harari initially self-published his book "Sapiens" under the title "From Animals into Gods" on Amazon. This early version sold around 2,000 copies and is now considered a rare collector's item due to its limited circulation. Despite his own writing skills, Yuval struggled with publication negotiations and the business aspects of publishing. After facing difficulties in finding a publisher on his own, his husband played a significant role in turning the situation around by hiring a competent literary agent, Deborah Harris, who helped significantly in bringing the book to a broader audience. This led to a professional translation and several rounds of editing, culminating in the book's successful English release in 2014 1.
