To find a publisher for your book, start by researching publishing houses that align with your genre and target audience. Prepare a compelling query letter and a polished manuscript or book proposal, depending on whether you’re writing fiction or nonfiction. Many authors begin by submitting to literary agents who can help find a publisher for your book more effectively, as they have industry connections and expertise. Be sure to follow submission guidelines carefully and consider reputable independent or hybrid publishers as well. Patience and persistence are key throughout this process.
