David Gaughran brings us the news that Apple launched a new portal today called Apple Books for Authors. This is primarily an information portal, and it has lots of useful info on marketing, ebook design, audiobooks, cover images, and so on, but if you drill down you will discover that there’s a new way to upload Epub ebooks to be sold in Apple Books.
You can find the upload page here. (You’ll still an iTunesConnect account to upload ebooks, but you can set that up using your existing Apple account.)
This is a huge change for Apple; they used to require that you use a macOS-only app to upload ebooks, or go through a distributor such as Draft2Digital. (Another way around this was to lease a Mac in the cloud, and run the app there.) Now everything is accessible via a web browser.
