Self-publishing (working without a traditional publisher to create, publish, distribute and promote your book) is one of the paths you might decide to take with your manuscript. You'll likely want to work with professionals to help with the global and line-by-line editing, cover design and promotion. You may also want to submit your book for review to help with your book's promotion.
