Choosing a literary agent is best treated as a structured comparison, not a hopeful leap. The right method is to evaluate every serious candidate—before and after an offer—across five dimensions: their sales track record, genre and category fit, client list and agency infrastructure, communication and working style, and contract terms and fees. Two ground rules frame everything that follows: a legitimate agent earns income only as a percentage of the deals they make, and the wrong long-term commitment is, as one industry guide bluntly puts it, worse than no agent at all.
Introduction: Why a Literary Agent Matters for Your Career
Agents spend most of their working hours reading submissions with one question in mind: can this manuscript be sold? As Editor World explains in its guide to the agent's role, that is a different question from whether a manuscript is good—a novel can be beautifully written and still be impossible to place because the market isn't there, the genre is saturated, or the book falls into a gap between categories. Authors who understand this filtering function are better equipped to evaluate offers of representation and to make productive use of the relationship once they're in it.
The Authors Guild's guidance on choosing an agent makes the corresponding point from the author's side: don't rush to sign. When an offer arrives, you are entering a long-term professional relationship, and the Guild advises taking time to explore your options and to be clear about what qualities matter most to you before you go on the market. This guide is for authors seeking traditional publication of fiction or nonfiction books—not screenplays, not self-publishing—and it offers a process, not a list of recommended individuals.
Literary Agent Evaluation Framework
Use the matrix below to score each agent you're considering on a consistent scale—say, one to five on every dimension—so that gut feeling becomes a documented comparison. The purpose is analytical: to identify the agent who best aligns with your specific manuscript and career goals rather than the one who simply responded first. Each row states what to verify and where the evidence-bearing answers come from.
| Dimension | What to verify | What a strong answer looks like |
|---|---|---|
| Sales Track Record | Recent sales in your specific category, not sales generally | Deals to publishers who publish books like yours, verifiable in Publishers Marketplace or similar deal databases |
| Genre & Category Fit | Demonstrated interest in and understanding of work like yours | The agent can articulate the commercial lane your book occupies—Big Five, mid-size, or small press—and shows enthusiasm for the category |
| Client List & Agency Size | Current client roster and agency infrastructure | Client references offered willingly; agency resources suited to your book's cross-format potential |
| Communication & Working Style | Editorial involvement, submission strategy, response habits | A stated working style you can imagine thriving under across multiple books |
| Contract Terms & Fees | Compensation structure and any pass-through expenses | Commission-only income; minor expenses listed in the contract and deducted from earnings, never paid up front |
The scoring works only when every candidate is judged on the same rows. Jane Friedman, publishing industry commentator, notes that the sales-track-record question is "usually the number-one sign of whether you have a good agent," which is why it anchors the matrix rather than sitting alongside the others as one consideration among many. The remaining criteria determine whether a strong seller is also the right partner for you.
