Walking into the children’s section of a bookstore can feel like standing before a library of history, all with the same friendly, oversized heads staring back at you. It’s an impressive sight that immediately sparks a question for parents, educators, and young collectors alike: just how many Who Was books are there? The short answer is that the main biographical series has published over 250 titles, but that number is just the beginning of the story.
The collection is a living, breathing library that grows by about two dozen books every single year. Understanding its scale isn’t just about a number; it’s about appreciating the vast and accessible world of history it opens up for young readers.
At a Glance: The Scope of the Who HQ Library
- The Core Series: The original Who Was? biography line, which began in 2002, now includes more than 250 distinct titles.
- The Expanded Universe: The entire Who HQ brand also features popular spin-offs—What Was?, Where Is?, and What Is the Story Of?—that add dozens more books about events, places, and cultural phenomena.
- A Rapidly Growing Collection: With approximately 24 new books released annually, the total number is a moving target, ensuring fresh content for eager readers.
- Curated for Impact: Subjects are carefully chosen for being the “first,” “best,” or for making a massive contribution to society, from scientists to sports heroes.
- Navigating the Titles: The key isn’t to read them in order (there isn’t one), but to explore thematically to match a child’s interests or school curriculum.
More Than Just a Number: The Scale of Who HQ
When people ask “how many Who Was books are there,” they are usually referring to the flagship biography series. Since its launch on February 18, 2002, with a quartet of titles—Who Was Sacagawea?, Who Was Ben Franklin?, Who Was Albert Einstein?, and Who Was Annie Oakley?—this series has grown into a powerhouse, with over 250 biographies.
But the world of the “bobblehead bios” is much larger. The publisher, Penguin Workshop, expanded the concept into a full-fledged educational universe called Who HQ. This umbrella brand includes several key spin-off series:
- What Was? This series tackles major historical events, bringing moments like the sinking of the Titanic, the American Revolution, and the Gold Rush to life.
- Where Is? Focusing on geography and architecture, these books explore world-famous places, from the Great Wall of China and the Grand Canyon to the White House.
- What Is the Story Of? This newer line dives into the history of cultural icons and creations, like the Olympics, the hamburger, or the Statue of Liberty.
Together, these series create a comprehensive and interconnected library of knowledge for middle-grade readers. The constant growth—about two new titles a month—means the collection remains relevant, adding contemporary figures like Greta Thunberg and Timbaland alongside historical giants.

The Anatomy of a Who HQ Choice: From Idea to Bookshelf
With hundreds of potential subjects, how does the Who HQ team decide who gets a book? The process is deliberate, focusing on creating a diverse and impactful library that stands the test of time. It’s a journey that takes nearly two years from the initial idea to the book landing in a child’s hands.
The ‘First, Best, or Biggest’ Rule
The editorial team at Penguin Workshop follows a clear set of criteria for selecting subjects. A person, place, or event is typically chosen if it was:
- The First: Pioneers who broke new ground. Think Amelia Earhart, the first woman to fly solo across the Atlantic, or Jackie Robinson, who broke the color barrier in Major League Baseball.
- The Best: Individuals who represent the pinnacle of their field. This includes figures like William Shakespeare, widely considered the greatest writer in the English language, or Michael Jordan, a basketball legend.
- A Major Contributor: People whose work or actions profoundly changed society. This category includes leaders like Martin Luther King Jr., activists like Susan B. Anthony, and innovators like Steve Jobs.
This framework ensures that every book offers a story of significance, whether it’s about a U.S. President, a groundbreaking artist, or a beloved author like Dr. Seuss.
The 18-to-24-Month Journey to Publication
Choosing the subject is just the first step. The production of a Who Was? book is a meticulous process that takes an average of 18 to 24 months.
- Step 1: Author & Research: A writer, often a specialist in children’s nonfiction, is contracted. They dive deep into research to distill a complex life story into an accessible, 112-page narrative.
- Step 2: Illustration and Design: While the text is being written, the iconic visual elements come together. Each book contains approximately 80 black-and-white illustrations that help readers visualize the era and key moments.
- Step 3: The Iconic Cover: Nearly every cover in the series’ history has been illustrated by Nancy Harrison. The distinctive “bobblehead” caricature style was inspired by the art in the New York Times Book Review, giving the series a unique and instantly recognizable brand identity.
This long-term, thoughtful approach is a key reason for the series’ enduring quality and popularity.

Your “Who Was?” Questions, Answered
Even with a plan, a few common questions pop up when navigating this massive series. Here are some quick, clear answers.
Q: Is there an official, complete list of all the Who Was? books?
A: The most accurate and up-to-date catalog is on the publisher’s official Who HQ website. While many fan sites, libraries, and booksellers maintain printable checklists, they can quickly become outdated due to the rapid publishing schedule. The publisher’s site is your best source for the absolute latest releases.
Q: Are the books numbered or published in a specific order?
A: No. Unlike series that follow a single narrative, the Who Was? books are standalone biographies. The first four were released as a group in 2002, but since then, titles have been published without any intentional sequence. This is a huge advantage, as it allows readers to jump in with any figure that sparks their curiosity.
Q: How often do new Who Was? books come out?
A: Who HQ consistently releases around 24 new books each year across all its series. This works out to an average of two new titles hitting the shelves every month, ensuring there is always something new to discover.
Q: Do all the books have the same authors and illustrators?
A: While Nancy Harrison is the signature artist for the covers, the interior illustrations and the writing are handled by a diverse team of authors and artists. Each author is chosen for their ability to write engaging nonfiction for children. For example, the series founder, Pam Pollack, and author James Buckley, Jr. have both penned numerous titles.
Start Your Collection with Confidence
The enormous number of Who Was? books isn’t a barrier; it’s an invitation. With over 250 biographies and counting, the series offers a pathway into nearly any topic a child might find interesting, from ancient history to modern-day pop culture.
Instead of trying to collect them all at once, think of the library as a resource to be used strategically. Here’s a quick guide to getting started:
- To support a school project, search for a key figure from the curriculum, like Leonardo da Vinci for a unit on the Renaissance.
- To fuel a personal passion, find a book that matches your child’s interests, whether it’s Who Was Stan Lee? for a comic book fan or Who Is Dolly Parton? for a music lover.
- To simply begin the journey, pick a globally recognized name like Walt Disney or a title from the original 2002 launch.
Each book is a gateway, offering a compelling story that makes history feel personal, exciting, and, most importantly, accessible. The only question left is: who will you meet first?
