[header] How to get a publishing agent [title] Consider whether you want an agent. [step] If your dream is for your book to be published by a large publishing house, you will probably want an agent. If you are targeting smaller publishers, you may want to forego finding an agent. <sep> (A) Even if an agent works the publishing house on a regular basis, they are unnecessary within an established publishing house. You will also want to be as responsive to people and businesses, but you will need a solid relationship with the publishing house because your book will be publishable if that person or business leads a search. (B) [substeps] Although an agent will collect 15% of your royalties, including your advance, as their commission, they will often be able to negotiate a better deal for you. You should weigh all these pros and cons and consider what you really want to do at this step in your writing career. (C) In this case, you should consider whether anyone you know would be a suitable agent. [substeps] You can search for a large publishing house in your area. (D) Therefore, it is a good idea to know if the company you are writing for will want an agent before putting a book on a publishing house website. [substeps] A large publisher might choose a smaller publishing house, rather than an other publisher.
