Often, Amazon comes to mind as a way of self-publishing e-books or paper books overseas. However, when I used international platforms such as Amazon KDP, tens of thousands of copies were posted a day. Likewise, Google Books and Apple Books were the same unless paid marketing was conducted. So I looked into various overseas self-publishing platforms. I started going into the semi-international platforms such as Kobo, Everand, Tolino, Barents & Novele, Overdrive, and SmashWords. And after visiting the Eurozone, South America, India, and Asia, where retailers are connected, I learned how to distribute them overseas. Overseas people use Google, an international search engine, but they do not use Naver. However, for Koreans, the sites such as Naver are public platforms. Likewise, the Eurozone, North America, India, and China each had local platforms distributed in local commercial districts. Even in the Eurozone, North America, and Oceania, it is easy to set up an account with Payonia and PayPal. I think reading this book can save us a lot of time because we have analyzed free/paid, distributed, platforms that are difficult to inspect depending on the content, and tax issues. It's time for us to earn foreign currency, too.
