Agent Spotlight: Marietta B. Zacker

This week's Agent Spotlight features Marietta Zacker of the Nancy Gallt Literary Agency.

Status: Accepting submissions.

Marietta 4-6-11 07 Lo Res Color About: "Marietta has professionally experienced every aspect of children’s books for over 15 years, working with authors, illustrators, publishers, educators and readers. As an agent, she is passionate about bringing those worlds together. She represents authors whose words make her pause, shiver or laugh out loud and illustrators who add a completely different dimension to the story being told. Marietta approaches her work with the knowledge that there are remarkable books of all genres, targeted to all ages, just waiting to be discovered." (Link)

She is also the book curator at Sparkhouse, an independent toy and book store in her hometown of South Orange, NJ.

About the Agency:

"The Nancy Gallt Literary Agency focuses on developing and finding the right home for the work of some of the most talented writers and illustrators in the children’s book industry. Established in 2000 by Nancy Gallt, and later joined by Marietta B. Zacker, we aim to bring to life stories and artwork that help young readers throughout the world become life-long book enthusiasts. We represent authors and illustrators who share and, through their work, exemplify that vision." (Link)

Web Presence:

Nancy Gallt Literary website.


AgentQuery & QueryTracker.

What She's Looking For:

Genres / Specialties:

Children's books only including picture books, board books, easy readers, chapter books, middle grade, young adult, non-fiction, historical fiction, graphic novels, fantasy, edgy, as well as illustrators and author-illustrators.  (Link, Link)

From an Interview (02/2010):

"Work that moves me – whether through words, illustrations or both. I look for manuscripts and illustrations that speak to the rich, complex, diverse world we live in and hope to work with people that are just as passionate as I am about the vital function children’s books serve in our society." (Link)

From an Interview (06/2009):

"I hope to help usher in a set of voices and depictions that will allow children and young adults of all backgrounds, ethnicities and countries to see themselves within the pages of our books. It is imperative that the voices and illustrations represent the population of children and young adults who crave to find themselves in the books they read - authentic voices and illustrations that move us beyond the stereotypes and are as real as the world we live in." (Link)

From Conference Notes (06/2009):

"Sometimes we shoot ourselves in the foot at these things when we tell a room full of writers what we love. Then all of a sudden we are bombarded with MS only about that. Often times, I don’t know what I want until I read it. I want something good." (Link).

What She Isn’t Looking For:

Ms. Zacker does not represent adult fiction or adult non-fiction.


"I want to see more depiction of what’s outside our world – true ethnicity, true representation of our populations. ALL kids need to be represented in books. More authentic ethnicity is needed." (Link)

"I always encourage clients to have a presence somewhere on the web, but to do what feels right for them. I think it's difficult to do it all well, so if branding yourself on the internet is new to you, I think it's best to take one social networking avenue at a time. I also feel it's important to remember that there are plenty of people who have mastered different aspects of the internet, so you should reach out to those who know more - again, especially when getting started. And although I feel it's extremely important to have a web presence, my decision to represent a client is not based on whether they do or do not have that presence." (Link)

Her advice to Writers:

"Write what you love, write what keeps you up at night, write what you know, write what you want to find out, but most importantly, write." (Link)

"Use your critique groups to revise, revise, revise before sending it [your manuscript] to an agent..." (Link)

"Please sit at a library or bookstore, go to the genre which you are currently writing for, start with A and just read. When you are tired, leave, come back the next day or week and pick up where you left off. Keep doing that until you get to Z." (Link)

Editorial Agent?

"I love the process of writing and illustrating as much as I love connecting the dots. I love talking through issues that are not quite ironed out in manuscripts or projects, zeroing in on places where things need to be tweaked and helping writers and illustrators put their best foot forward. However, it is also true that I neither want to be a member of the person’s critique group nor take the place of an editor who will take the book in the direction that works best for them and their publishing house. These are fine lines to walk, to be sure and sometimes difficult to discern." (Link)


"When people hide behind the veil of professionalism when querying - never realizing that by stripping their personality and their writing ability from this first impression, they deny themselves the opportunity of being discovered.  I expect queries to be polished, yes, but also to give me an insight into the writer AND the writing; stock queries are 'for the birds." (via e-mail)

Query Tips:

"...Please don’t pretend that we don’t know you. Indicate that you had once submitted before and now you are submitting again. I don’t know why some writers think they can pretend like we don’t know you or won’t remember you. We will. So, just mention it in your query." (Link)

What's the Buzz?

Ms. Zacker joined Nancy Gallt Literary and became an agent in early 2009, but she has over 15 years experience in the children's book industry.  She has a  growing list of clients and sales and has made a fabulous impression on the writing community with her passion and wit.  She has a unique view of the industry being both an agent and an indie bookstore curator.  Follow her on Twitter for updates and insight.

I had the pleasure of interviewing Ms. Zacker and found her to be very nice, communicative, and gracious. See the interview here.

  1. I've been working with Marietta since the passing of my agent at Nancy Gallt. She's been she's extremely professional, yet very down to earth and fun to talk to. I can't offer up any contact info, but I believe she works in tandem with Nancy Gallt, so if you query Nancy, Marietta may be the one reading or responding to it. Overall, great lady, who knows the biz inside & out! xoxo Hilary

  2. Thank you so much, Hilary. Your input is greatly appreciated!

  3. Thanks for your research on this agent, Casey. With what little info there is about her, I think you did a great job!

  4. I just met Marietta and I can tell you her pet peeve is when people do not even try to properly pronounce her name. It is Mad-ee-etta with a soft R roll on the "d" sound. She was very nice, very friendly, and easy to talk to. She doesn't say what specifically she is looking for because she finds that that comes back to haunt her in piles and piles of similar submissions.

    Hillary - she alluded that someone at her agency had died but of course she wouldn't give details and everyone respected her privacy in this issue. But I suspected it was Nancy Gallt's husband. My sincerest condolences. It must have not only been a huge loss more than words can express for Nancy, but for all his clients as well. So sorry to hear this sad news.

  5. Thanks Crystal!

    Sheri! When I saw she was just at the NJ conference, I was hoping you had met her or heard her speak. Thank you so much for chiming in!

  6. I was going to try to fill you in, but Sheri beat me to it. I saw Marietta on the Agent Panel at NJ SCBWI as well. Very spunky and fun.

    My friend who had a one-on-one critique said she was sensitive and sweet and sincerely seemed to want to help her with her manuscript.

  7. She sounds great. I've updated the Spotlight as more info has come to light from the NJ conference.

    Thank you for your input as well, Corey!

  8. Hey all -

    I've been in contact with Marietta since this posting. She's been absolutely wonderful.

  9. i just had lunch with her in LA and she is awesome - smart and passionate. love her.

  10. Awesome, Shelli! She seems like such a lovely person.

  11. Updated 01/20/10 to include the agency's new website and submission guidelines!

  12. Do you know if she's a no response = no agent? I never did hear back from my query, and in those cases you never know if something went wrong and they just didn't get it, or if they got snowed under, or if their policy is always one of responding only when interested.

  13. Anon, from what I can tell she does send a response but it looks like she's averaging two months or so on queries, sometimes longer. If it's been especially long time, you may want to consider re-querying.

  14. Just did an update on Ms. Zacker's profile. There are some new interviews and quotes and the agency appears to have a no-response means no policy now.

    Best to all who query~!

  15. The agency's website no longer mentions attaching 3 chapters (just pasting in the first 5 pages). And when you do send them an email, the auto reply states:

    "However, if you included an attachment, the e-mail will be automatically deleted."

  16. Thank you, Anon! I've updated the submission policy on the profile.
