Marcy Posner An agent with Folio Literary Management (see other agents at this agency). About I have spent a lifetime in books. I started out with a brief stint as a librarian, but found it a bit too staid, so moved on to publishing. My first job was at Pinnacle Books where as assistant to the President I was given a book to edit the third week of my employment. I then moved on to Rodale Press and then Salem House where I helped bring British books to the US, finally moving up the publishing ladder to Pantheon’s Associate Publisher, where I worked with some of the major cultural icons of our time. After fifteen years on the editorial side of the business, I made the jump to agenting – spending twelve years at the William Morris Agency as an agent and as Vice President and Director of Foreign Rights; five years as president of my own agency; five years at Sterling Lord Literistic as an agent and Director of Foreign Rights; and I’m now here – and very happy – at Folio. Editorial skill and a deep knowledge of the publishing industry sets me apart from many of my colleagues. When I work with my authors, I’ll focus editorially on how to make the book as strong as it could be – whether that book be terrific women’s fiction or an extraordinary YA debut (or any of the other categories I represent). During that process, I’m able to bring to bear all the institutional memory I possess, knowing which editors and which publishing houses have a penchant for a certain subject, or a different voice, or a particular kind of author.

Never pay an agent an up-front fee. That is not how literary agent representation works. Agents earn a commission only after they've landed a publishing deal for you. Also, agents scarcely ever contact writers. If an agent that you haven't queried contacts you about representation, be suspicious. Look up the agent and check if the email address is correct for that agent/agency.
