Every book lives in one workspace: the book itself, an edition for each language, and the formats of each edition (ebook, paperback, hardcover).
What you need: a title and the language you wrote the book in.
What you get: one place that holds every edition of the book, so a change made once can reach every edition and format.
Example: the showcase book has an English original, a Polish and a German edition, and each edition has an ebook and a paperback.
What you're publishing: when you add a book, say what it is: a novel, short stories, poetry, non-fiction, a memoir or a workbook. Each edition then starts with the formats books like it usually have, each format with their trim, paper and ebook look, and the book with an ISBN plan and the stores that suit it. Change any of them as you go. On the book's page, "Set every format to these" puts the kind's settings back on every format.
No manuscript to hand? The Books page offers a sample book of the kind you chose: a novel, short stories, poems, a guide, a memoir or a workbook, ours and invented, with its text and cover art, ready for every step. It doesn't count as your free book.
