Fancy Nancy is a 2005 children's picture book written by Jane O'Connor and illustrated by Robin Preiss Glasser. The book spent nearly 100 weeks on the New York Times Best Seller list, launching a series that now numbers more than 50 books, selling 24 million volumes. Fancy Nancy has been on Publishers Weekly’s bestseller list for picture books, was a Children’s Book-of-the-Month Club selection and a Junior Library Guild Selection. It also won a "Borders 2006 Original Voices" award  and has been translated into 18 languages, including Hungarian and Hebrew. In April 2012, Nancy was featured in her first chapter book, Nancy Clancy: Super Sleuth. Books in the Fancy Nancy series have now spent more than 300 weeks on the New York Times Best Seller list, and in the fall of 2012, "Fancy Nancy the Musical" was produced by Vital Theatre Company in New York City.
Fancy Nancy is a young girl with a larger than life personality, who adores all things fancy. She always dresses extravagantly, wearing boas, tutus, ruby slippers, fairy wings, and fuzzy slippers. Nancy loves using big fancy words such as "iridescent", "ecstatic", and "extraordinary" and anything in French. She has redecorated her bedroom with everyday items, such as feather boas, Christmas lights, paper flowers, and hats. Her favorite doll is named Marabelle Lavinia Chandelier.
In Nancy's opinion, her family is ordinary and dresses rather plainly, so Nancy decides to hold a class in the art of fanciness for her family. They oblige, and Nancy helps to dress them in bows, ornaments, top hats, and gaudy scarves. "Ooo-la-la!" Nancy cries in delight. "My family is posh! That's a fancy word for fancy."
Jane O'Connor is vice-president and editor-at-large for Penguin Books for Young Readers! She has written more than thirty children's books. Her first adult novel, Dangerous Admissions: Secrets of a Closet Sleuth came out in July 2007.
O'Connor came up with Fancy Nancy on a summer evening. As she describes it, "It was after dinner one evening that the title just came to me," she recalls. "I sat down and wrote the first and last paragraphs. The rest of the story took me awhile, but the beginning and the end just flew into my head." O'Connor is quick to point out that much of the book's success is Glasser's artwork. She wrote the book in 2002, but it didn't come out until 2005, because her editor, Margaret Anastas, insisted on Glasser as the illustrator who was busy with other projects.
Robin Preiss Glasser
In 2013 Glasser was named 2013 Illustrator of the Year by the Children's Book Council for Fancy Nancy and the Mermaid Ballet after more than 1 million young people cast their votes  in the 6th annual Children's Choice Book Awards.
Fancy Nancy has spawned a line of toys and games focusing on dress-up and role play targeted towards preschoolers and children aged 5 to 7. In addition, the Fancy Nancy brand includes licenses for clothing, paper party goods, crafts, and more. Numerous bookstores and libraries around the United States have hosted events including readings by both Jane O'Connor and Robin Preiss Glasser, costume contests, “Fancy Nancy” days and tea parties.
In 2012, Fancy Nancy the Musical was produced Off-Broadway by Vital Theatre Company. The musical is mainly based on Fancy Nancy and the Mermaid Ballet, with Book and Lyrics by Susan DiLallo and Music and Lyrics by Danny Abosch. The show was very well-received and is currently running in New York City and on tour. The Original Off-Broadway Cast Recording of Fancy Nancy the Musical was released on Ghostlight Records in 2013.
