What Does a Literary Agent Actually Do?

Updated May 2026.

A literary agent represents authors in the business of publishing. They sell manuscripts to publishers, negotiate the terms of the deal, manage the publishing relationship on the author's behalf, handle subsidiary rights (foreign translation, audio, film and television), and serve as the author's advocate for the long arc of the career. They are not editors, marketers, or publishers. They are the author's business representative in an industry where most authors lack the relationships, the information, and the negotiating leverage to operate alone.

For authors pursuing traditional publication, the literary agent is usually the necessary intermediary between manuscript and publisher. Most major publishing houses acquire books almost exclusively through agents. Understanding what agents actually do, what they're paid for, and where their value comes from is essential before you begin querying. This article explains the role.

What a Literary Agent Does, Step by Step

An agent's job is not a single activity but a sequence of distinct functions that together constitute representation. Authors who understand each function are better equipped to evaluate offers of representation and to make use of the agent relationship once they're in it.

1. Evaluating manuscripts and selecting authors

Most of an agent's time is spent reading. Agents read submissions to identify manuscripts they can sell, which is a different question from whether the manuscript is good. A novel can be beautifully written and still be impossible to place because the market for it isn't there, the genre is saturated, or it sits in a gap between categories. Agents are looking for manuscripts that meet quality standards and that they have a credible path to selling.

When an agent offers representation, they're making a substantial commitment. They'll spend months working with the author on revisions, months more shopping the manuscript to editors, and additional time managing the deal and the publication. They take on this work without payment in the hope of earning commission when the book sells. The agent's selection of which authors to represent is therefore an investment decision, and it's why they're selective.

2. Providing editorial feedback before submission

Most agents request revisions before sending a manuscript out to editors. Some agents work hands-on with editorial detail; others provide broader structural notes and expect the author to execute. Either way, the agent's pre-submission editorial role is to make the manuscript as strong as possible before it reaches the acquiring editors who will decide whether to acquire it.

Agent editorial notes are different from professional editing. Agents focus on what's needed to sell the book: marketability, opening pages strength, voice consistency, structural clarity. They typically don't perform line editing or copy editing themselves. Authors arriving at an agent with a manuscript that's already been through professional editing usually move through the agent's pre-submission revision phase more efficiently.

3. Submitting manuscripts to publishers

When the agent and author agree that the manuscript is ready, the agent submits to acquiring editors at publishing houses. This is the function that most distinguishes agents from anything an author could do alone. Agents have specific editor relationships at specific houses. They know which editors are looking for which kinds of books, which editors have empty slots in their lists, which editors have recently lost an author and need to replace them.

Submission is usually done in rounds, with the agent's top choices targeted first, often editors they have strong personal relationships with. The first round might be 8 to 12 editors. If the first round doesn't produce an offer, the agent moves to a second round with the next tier of editors. The pattern of responses across submission tiers shapes the agent's read on what's working and what isn't.

4. Negotiating the deal

When a publisher offers to acquire the book, the agent negotiates the terms. This includes the advance amount, the royalty rates, the rights bundle (what the publisher gets and what the author retains), the publication timeline, deadlines for delivery and revision, the territory of publication, and dozens of other terms that shape the author's experience and earnings.

Negotiation is the single most concentrated source of agent value. A good agent on the same book deal as an unagented author will typically secure better terms by a substantial margin, often more than enough to offset their commission. The publisher's standard offer is the publisher's starting position. The negotiation determines where the deal actually lands.

When multiple publishers want the same book, the agent runs an auction or a best-bids process. This is where agents earn outsized value: the difference between a single-publisher deal and a competitive auction can be many times the advance amount, plus better terms on every other dimension.

5. Managing the publishing relationship

After the deal is signed, the agent continues to manage the author's relationship with the publisher across the book's lifecycle. This includes shepherding the manuscript through the publisher's editorial process, advocating for the author when concerns arise about cover design, title, marketing budget, or other production decisions, tracking publisher commitments on marketing and publicity, and managing royalty statements once the book is published.

If problems arise (a publication delay, an editorial change at the house, a marketing budget that doesn't materialize), the agent is the author's representative for raising those issues. Authors who try to negotiate these conversations directly with their editor often damage the relationship; the agent is the intermediary who can have those conversations without affecting the author's working relationship with their editor.

6. Selling subsidiary rights

Many traditional publishing contracts retain certain rights for the author or for the agent to license separately: foreign translation, audio, film and television, dramatic adaptation, merchandising. A good agent actively works these rights, either directly or in partnership with co-agents who specialize in foreign sales or film and television.

For most books, sub-rights income is small or zero. For some books, it's substantial. A film option on a successful novel can pay tens of thousands of dollars before the option is even exercised. A successful audio production can become a meaningful income stream. Foreign translation deals across multiple territories can accumulate into significant revenue. The agent who actively works sub-rights is potentially adding income that the publisher doesn't generate.

7. Advocating for the career

The most experienced agents represent authors across multiple books and multiple decades. They think about the author's career trajectory, not just the current book. They help the author decide what to write next, navigate the transition between book one and book two, manage relationships across multiple publishers if the author moves houses, and provide perspective on the long arc of a career that's hard to see from inside it.

For an author with a successful first book, the second book is often where careers are made or lost. The agent's role in that transition is significant and is one of the reasons the author-agent relationship matters beyond any single deal.

How Literary Agents Get Paid

Understanding agent compensation is essential because the structure shapes the incentives. Legitimate literary agents work on commission, never on fees.

Standard commission structure

The standard commission structure in U.S. publishing is 15 percent of domestic sales and 20 percent of foreign and sub-rights sales. The agent takes their commission directly from the publisher's payments to the author. When an advance check arrives at the agency, the agency deducts the commission and forwards the remainder to the author. When royalty payments arrive, the same process applies.

Some agencies have slightly different commission structures (10 percent on domestic for a few legacy agencies, 25 percent on foreign for some smaller agencies, percentage variations for audio or film). Any structure that varies significantly from the 15/20 standard should be examined carefully.

What agents don't charge for

Legitimate literary agents do not charge:

• Reading fees. Considering your query and manuscript is part of the agent's job. They don't charge to read it.
• Editing fees. If an agent thinks a manuscript needs editing, they may suggest professional editing or do their own editorial review, but they don't charge separately for it.
• Marketing or promotion fees. The agent's marketing of the manuscript to publishers is part of representation, not a separate paid service.
• Membership or representation fees. You don't pay to become a client.
• Office expense fees. Some agency agreements pass through specific expenses (copying, foreign mailing), but these should be transparent, capped, and minor.

If anyone calling themselves a literary agent asks for money up front, that's a red flag. The agent makes money when the book sells. Until then, both the agent and the author are working on speculation.

What Literary Agents Don't Do

The clearer picture of agent responsibilities comes partly from understanding what agents are not. Several common misconceptions:

Agents don't write or co-write your book

The book is yours. The agent helps refine it through editorial notes and helps revise it through the submission process, but they don't write. Manuscripts arrive at agents complete, or in the case of nonfiction, in proposal form with substantial sample writing already done.

Agents don't replace professional editing

Agent editorial notes focus on what's needed to sell the book, not on copy editing or proofreading or line-level prose work. Manuscripts arriving at an agent with significant unfixed editorial issues will either be rejected or require substantial revision before submission. Most agents recommend that authors invest in professional editing before querying, particularly for first-time authors. See our guide on whether you need a book editor either way.

Agents don't guarantee a sale

A signed agency agreement means the agent will represent the manuscript, not that the manuscript will sell. Some agented books don't sell. The agent's job is to give the manuscript the best possible shot at finding a publisher. The outcome depends on the manuscript, the market, the timing, and many factors outside any agent's control.

Agents don't market your book to readers

Agents market manuscripts to publishers. They don't run reader-facing marketing campaigns, manage your social media presence, or build your author platform. Those are the author's responsibilities, sometimes in partnership with the publisher's marketing team after the book is acquired.

Agents don't replace publishers

Some authors confuse the roles. The agent sells the manuscript to a publisher; the publisher produces, prints, distributes, and markets the book. The agent represents you in the relationship with the publisher but doesn't perform the publisher's functions.

When You Need a Literary Agent and When You Don't

Whether you need an agent depends on what you're trying to do. The answer is clearer than first-time authors sometimes expect.

You need an agent if you want

• To be published by a major U.S. or U.K. publishing house (Penguin Random House, HarperCollins, Simon and Schuster, Hachette, Macmillan, and their imprints). These houses acquire almost exclusively through agents.
• To negotiate a serious deal with any traditional publisher. Even when smaller presses accept unagented submissions, an agent typically secures better terms.
• To sell foreign rights, audio rights, or film and television rights in any concerted way. These rights are difficult for individual authors to work without representation.
• To build a multi-book career with serious traditional publishing involvement.

You don't need an agent if you're

• Self-publishing. The agent's primary function (selling to publishers) is irrelevant when you're publishing yourself. Some self-publishers later sign agents for foreign rights or film deals, but the agent isn't necessary for self-publishing itself.
• Submitting to small or independent presses that accept unagented submissions and you understand contract terms well enough to negotiate your own deal. Many smaller presses publish unagented authors successfully.
• Publishing through a hybrid press where the relationship is direct.
• Pursuing forms of publication that don't go through traditional publishers (academic publishing where authors and university presses negotiate directly, professional or niche presses with established author-publisher relationships).

What to Look for When Evaluating a Literary Agent

When you receive an offer of representation, you're making a long-term commitment. The wrong agent is worse than no agent. Evaluate carefully on several dimensions.

Track record

Verifiable recent sales in your category. Not just sales generally; sales of books like yours, to publishers who publish books like yours. Publishers Marketplace and similar deal databases provide this information. An agent who can't show a recent sales record in your category may not have the editor relationships needed to sell your book.

Communication and working style

Agents vary widely in communication style. Some are highly hands-on with editorial detail and frequent communication. Others are more business-focused, with editorial work delegated and less frequent contact. Neither is wrong. The fit between the agent's style and yours is what matters. Ask in the offer call.

Agency infrastructure

Some agents are solo practitioners. Others are part of larger agencies with foreign rights teams, film and television teams, and audio rights specialists. The agency infrastructure shapes what can be done with your book beyond the primary U.S. deal. For books with cross-format potential, agency infrastructure matters more.

Client references

A legitimate agent will let you speak with one or two of their current clients before you sign. This is standard practice. An agent who refuses to provide client references is signaling something you should pay attention to.

The agency agreement itself

Read every clause. Standard terms include the commission structure (15/20 typically), the term of representation, what rights the agency handles, what happens if either party wants to end the relationship, and how disputes are handled. Some clauses are negotiable. If something feels wrong, ask. If the agent won't explain or negotiate clauses that concern you, that's information about how the working relationship is likely to go.

Editing Before You Query an Agent

The manuscript you send to a literary agent is the manuscript the agent will evaluate. A polished manuscript stands a real chance of representation. A manuscript with structural issues, inconsistent voice, or persistent grammatical errors does not, regardless of how strong the underlying story is. Most agents reject in form letters at the query stage and never tell you why.

Editor World's book editing services include developmental editing, line editing, copy editing, and proofreading for fiction and nonfiction at every stage. Authors who are preparing to query agents most often invest in copy editing for prose polish and, where structural issues remain, developmental editing for the underlying architecture. You browse editor profiles by genre experience and verified client ratings, select the editor whose background matches your manuscript, and message them directly before submitting to discuss your goals. A free sample edit is available on request. A certificate of editing confirming human-only editing is available as an optional add-on.
