When you first upload your books to Amazon it allows you to choose two browse categories. After your book is published, you can request them to add it to another 8 or so categories. Some will tell you can have a maximum of 10 categories, while others say you can go higher. I have found it a challenge to find more than 10 categories for my books.

There are several steps to the process. First off, login to your Kindle Direct Publishing account and click on the Bookshelf link.

You’re asking two separate, but distinct questions.

I would suggest changing your identity from ‘writer’ to ‘author.’

According to Wikipedia: Author vs Writer We often use the words author and writer interchangeably. But indeed, both these words are quite different. A writer is a person who writes a book, article, or any literary piece, while an author is essentially the person who originates the idea, plot, or content of the work being written.
