Circulating Now Celebrates 20 Years of Harry Potter!

By Erika Mills ~

J. K. Rowling published Harry Potter and the Philosopher’s Stone, the debut novel in the seven-book series that became a pop culture phenomenon, on June 26, 1997. Over the past two decades, the exploits of the boy wizard and his friends have spawned successful cinematic and theater adaptations, developed a devoted and enthusiastic global fandom, inspired admirers to create Harry Potter-themed art and media, instilled important moral lessons into a generation of young people now coming of age, and even added to the English lexicon! (See: “Muggle” in the Oxford English Dictionary.) The NLM History of Medicine Division celebrates the 20th anniversary of Harry Potter with special events onsite, as well as a five-post series in Circulating Now.

While the world reflects on 20 years of Harry Potter, we look back further in time—to the Renaissance—at the history that inspired some of the magic, characters, and settings in book and film series. For the week of June 26th, NLM hosts a special display of rare books from our world-renowned collections, produced by real-life naturalists like Nicolas Flamel and Paracelsus, who feature as figures in wizarding history in the Harry Potter series; as well as Ambroise Paré, Conrad Gessner, and others whose work in alchemy, astrology, and natural philosophy helped shape Western science and influenced Harry Potter. The display is accompanied by the our traveling exhibition Harry Potter’s World: Renaissance Science, Magic, and Medicine, which explores Harry Potter’s roots in the Renaissance and highlights the important ethical topics Rowling’s stories examine.

For those who cannot visit in person, we have launched a permanent, online curated collection of the 15th, 16th, and 17th-century books that will appear in the week-long display, as well as related works. All are digitized and accessible through the online adaptation of Harry Potter’s World.

In addition to the special display, we are offering two lectures as part of the week-long appreciation of the Harry Potter series. On June 27th at 2:00pm, the curator of Harry Potter’s World, Elizabeth Bland, presents “A Look into the Pensieve: Reflections on Harry Potter at Twenty Years.” Then, on June 29th at 2:00pm, Stephen Greenberg, PhD, Head of Rare Books & Early Manuscripts at NLM gives a talk titled “Monsters in the Stacks: How Harry Potter Came to NLM.” Both lectures will be live-streamed globally. More information is available on the NLM History of Medicine Lecture Series website.

Circulating Now kicks off its celebration of two decades of Harry Potter with this post, followed by an interview with Elizabeth Bland, a look at our traveling and online exhibition Harry Potter’s World: Renaissance Science, Magic, and Medicine, an interview with Stephen Greenberg, and an exploration of the NLM herb garden, which features plants used historically for medicinal purposes that are similar to the plants Harry Potter and his classmates study in their herbology class.

  1. Thank you NLM for marking this important event in literary history! Harry Potter encouraged young people to be excited about reading while J.K. Rowling brought new life to some of these ideas from the Renaissance. I look forward to viewing these rare books and learning more about the NLM herb garden.

  2. Reblogged this on WL Hawkin and commented:

    Our fascination with magic knows no bounds. It grows and shapes our culture. We are muggles searching for the portal that can whisk us free of our mundane lives.

  3. Hi,

    The second book in the Harry Potter series is, “Harry Potter and the Chamber of Secrets.” Enjoy reading it!

  4. Harry Potter, and more importantly, Joanne Rowling, certainly changed my life forever with her books. She made me go down the path of being a writer, and no words will ever accurately describe how grateful I am for her magical story. I don’t think she will ever see this comment, but her determination to get her book published certainly helped to change the future for the better. Thank you J.K. Rowling, I will always be indebted to you for your hard work and perseverance.
