A literary agent is a professional who represents authors and their written works to publishers. They help writers navigate the publishing industry, offering guidance on manuscript preparation, submission strategies, and contract negotiations. Agents typically earn a commission, usually around 15%, from the sales of the books they represent. Literary agents play a crucial role in connecting authors with publishers, ensuring that manuscripts reach the right audience. They often have established relationships with editors and publishing houses, which can increase the chances of a book being accepted for publication. Agents also provide valuable feedback to authors, helping them improve their work before submission.
