What is an agent?

In the book trade, “agent” almost always means a literary agent: a representative who offers your manuscript or proposal to publishers, negotiates the deal, and collects a percentage of what you earn from that deal. They work for you, not for the publishing house. That distinction matters. An editor’s job is to acquire books that suit their list. An agent’s job is to find the editor who will pay fairly for yours, and then to keep the relationship from going sour when the first royalty statement arrives.

Three professions sharing one word

Writers mix these up, and it costs them years. A literary agent sells books and usually the subsidiary rights around them (translation, audio, serial, sometimes film). A film and television agent represents scripts, writer-directors, and often the dramatic rights in existing books. A talent agent represents actors, presenters, and other performers. Some large agencies house all three under one roof. They are still different desks, different codes of practice, and different ways in.

If you have written a novel, you need a literary agent who handles that genre in that territory. Sending the novel to a film agent’s general inbox is like posting a casserole to a violin teacher because both involve “performance.”

What an agent is not

They are not a publisher. They do not print your book, assign an ISBN, or take it into Waterstones. They are not a freelance editor you hire by the hour — though a good agent will tell you, sometimes bluntly, that chapter four is where the book dies. They are not a publicist. They are not a vanity press with a nicer letterhead.

Above all, a legitimate literary agent is not someone who charges you to read the manuscript. The Association of Authors’ Agents in the UK and the Association of American Literary Agents in the US are explicit about this. Income comes from commission on deals. If the business model is “pay us first, then maybe we submit it,” you are not looking at an agent. You are looking at a reading service that has borrowed the costume.

Why the job exists

Publishers closed most of their unsolicited fiction piles because the volume made serious reading impossible. Agents took on that first cut. In return they ask for exclusivity in the markets they cover, and a split of the proceeds. It is a trade-off, not a coronation. Plenty of poets, short-story writers, and authors at small presses work happily without one. Plenty of novelists will not be read by a major house until an agent puts the envelope on the right desk.

So the useful question is not “What is an agent?” in the abstract. It is “What kind of agent, for this book, in this market?” The rest of this guide is that question, taken slowly.
