This spring marks a somber anniversary: five years of escalating attacks on books and libraries across the United States. Throughout 2026, various organizations are commemorating this milestone, not only to underscore the protracted and intricate nature of this ongoing struggle but also to champion and celebrate the dedicated efforts to safeguard equitable access to literature and vital library resources. The current wave of book challenges and bans, which gained significant momentum in the spring of 2021, represents a concerning trend in the nation’s intellectual freedom landscape.

Documenting the Scale of Literary Censorship

The most quantifiable aspect of this trend is the identification and tracking of banned books. Currently, four authoritative lists provide insight into titles that have been officially removed or restricted. These lists are compiled based on reported and published data, as well as inclusion on state-sponsored banned titles registries. However, it is crucial to acknowledge that the vast majority of books facing censorship in America go undocumented. Consequently, the figures derived from these lists represent only a fraction of the pervasive nature of literary censorship.

PEN America, a prominent literary and free expression organization, has meticulously documented book bans in public schools nationwide since the 2021-2022 school year. Their reports indicate that approximately 23,000 books have been banned based on their documented cases. However, the reality is undoubtedly more extensive. This number is likely a multiple of the documented figure when considering the prevalence of "quiet censorship"—the subtle, often unannounced removal or restriction of materials—as well as the observed deceleration in book purchases by libraries and the pervasive chilling effect that discourages the acquisition of potentially controversial titles.

Official Lists and Tracking Methodologies

Each year during National Library Week, the American Library Association (ALA) releases its "Top Ten Most Challenged Titles" list. The ALA has been tracking challenged books—titles against which a complaint has been lodged, regardless of whether they are ultimately banned—since 1981, and has published its "Top Ten" lists annually since 2001. These challenges, reported nationwide across libraries, capture a broad spectrum of titles and institutions.

PEN America’s documentation, while a more recent endeavor, provides crucial data on book bans specifically within public schools. Like the ALA, PEN America relies on reports submitted to them and information gleaned from news coverage. Both organizations aim to highlight the most frequently targeted titles each year, thereby identifying current trends and exploring the underlying themes of the books under scrutiny. PEN America’s reports also offer a poignant observation: the top-banned titles often change annually because once a book is banned from schools, it is no longer present in those educational environments. This dynamic contrasts with the ALA’s lists, which tend to show greater consistency in titles over time due to their broader scope encompassing more libraries. This consistency underscores a critical point: the censorship occurring within schools is not an isolated phenomenon and often extends beyond educational institutions.

The Genesis and Evolution of the Book Ban Movement

The significant surge in book bans across America began in the spring of 2021. This movement can be understood as a progression of right-wing rhetoric that initially focused on "reopening the schools" in the aftermath of the COVID-19 pandemic. This was followed by campaigns advocating to "unmask the kids" and resist vaccination mandates. From its inception, critics have argued that this attack on books is not fundamentally about the literature itself, but rather a broader assault on principles of inclusivity and, in the language of its proponents, "diversity, equity, and inclusion" (DEI). The movement also targets comprehensive sexuality education, now frequently reframed as "gender ideology" or "sexual orientation and gender ideology" (SOGI). Furthermore, it extends to challenging science-based facts that diverge from a particular ideological viewpoint, including social-emotional learning and climate change. Ultimately, the focus is not on the books but on the ideas they contain and the diverse communities they represent.

State-Level Mandates and Unofficial Lists

Beyond the efforts of national organizations, two U.S. states have implemented legislative mechanisms that have resulted in official state-wide book bans. While three states possess the legislative power to mandate book removals from all public schools, only Utah and South Carolina have actively exercised this authority. As of the current reporting, Utah has banned 34 books from its public schools under a law enacted in 2024. Similarly, South Carolina has banned 22 books through its 2024 legislation. Tennessee, the third state with such legislative capabilities, has seen numerous local book bans but no official statewide decree to date.

Florida, while lacking the formal mechanisms for an official state-banned book list, has seen its State Board of Education compile and disseminate a list of specific books that schools have been directed to remove. The books targeted by these state-sanctioned actions, whether official or unofficial, are often incorporated into the broader counts maintained by both the ALA and PEN America.

Analyzing the Most Targeted Titles and Authors (2021-2026)

As the nation enters its fifth year of this ongoing censorship, an examination of the targeted books reveals significant insights. By synthesizing data from the ALA’s Top Ten Lists, PEN America’s reports, and the official state-banned lists from Utah and South Carolina between 2021 and 2026, a clearer picture emerges. It is important to note that Florida’s unofficial list is not included in this specific analysis due to its unofficial status, although the books affected by it are represented in the ALA and PEN America data. The ALA’s data encompasses five full years, while PEN America’s accounts cover four full school years, with their fifth year of data for the 2025-2026 school year anticipated for release in the fall.

A total of 11 distinct lists were evaluated: five from the ALA, four from PEN America, one from Utah, and one from South Carolina. The term "banned" is applied broadly to encompass all these instances, as the books "challenged" by the ALA are frequently the subject of actions aimed at their removal—whether through relocation, restriction, redaction, or outright prohibition, as tracked by PEN America and mandated by state lists.

The Most Banned Books and Authors, 2021-2026

Over the past five years, certain titles have emerged as recurring targets of censorship efforts. These are the books that have most frequently appeared on the ALA’s and state-sanctioned lists.

• The Perks of Being a Wallflower by Stephen Chbosky (8 appearances)
• Gender Queer: A Memoir by Maia Kobabe (7 appearances)
• All Boys Aren’t Blue by George M. Johnson (6 appearances)
• The Bluest Eye by Toni Morrison (5 appearances)
• Speak by Laurie Halse Anderson (5 appearances)
• The Hate U Give by Angie Thomas (5 appearances)
• Thirteen Reasons Why by Jay Asher (4 appearances)
• Out of Darkness by Ashley Hope Pérez (4 appearances)
• Lawn Boy by Jonathan Evison (4 appearances)
• Absolutely True Diary of a Part-Time Indian by Sherman Alexie (4 appearances)

Complementing the list of most banned books is an examination of the authors most frequently targeted. This reveals patterns in the subject matter and themes that critics seek to suppress.

• Ellen Hopkins (8 appearances, across multiple titles)
• Sarah J. Maas (6 appearances, across multiple titles)
• George M. Johnson (6 appearances, primarily for "All Boys Aren’t Blue")
• Maia Kobabe (7 appearances, primarily for "Gender Queer: A Memoir")
• Toni Morrison (5 appearances, primarily for "The Bluest Eye")
• Angie Thomas (5 appearances, primarily for "The Hate U Give")
• Laurie Halse Anderson (5 appearances, primarily for "Speak")
• Jonathan Evison (4 appearances, primarily for "Lawn Boy")

Ellen Hopkins holds the top position for several reasons. Her work has historically been a frequent target for censors, and in the current wave, she possesses a larger catalog of titles susceptible to challenges than many other authors. For decades, Hopkins has been a vocal advocate for the right to read, explaining that her exploration of challenging themes reflects the realities faced by young readers. It is noteworthy that Sarah J. Maas, another author who has been among the most banned for five years, has remained largely silent on the censorship of her work.

Of the eight authors most frequently banned since 2021, six identify as members of marginalized genders, further highlighting the discriminatory nature of many censorship efforts.

Deeper Analysis: The Age and Context of Banned Books

One frequently surprising statistic regarding banned books is that the vast majority are not recent publications. In many instances, these are titles that have been in circulation for years, even decades. Several factors contribute to this phenomenon.

Firstly, the process of acquiring new books for school libraries can be lengthy. School libraries do not acquire materials year-round, and their budgets can fluctuate annually. As school libraries serve their specific communities, acquisitions may not follow the same patterns as public libraries. They may purchase books to fulfill curriculum requirements or replace worn, damaged, or missing copies of older titles more frequently than their public library counterparts.

Secondly, those engaged in book banning often lack a comprehensive understanding of how library collections are built and curated. Books do not simply appear on library shelves; they undergo multiple layers of selection and review, beginning with professional trade journals that librarians consult before making purchasing decisions. Conversely, the unprofessional review sites developed by individuals actively involved in censorship efforts often rely on volunteers who gather information without adhering to established bibliographical standards.

The average publication date of the most banned books in America between 2021 and 2026 is 2008. This indicates that, on average, the books targeted over the last five years are 18 years old. Many of these books were likely available and widely read by students when the current proponents of censorship were themselves teenagers. For example, "The Perks of Being a Wallflower," the most banned book in this period, was published in 1999.

Considering the median publication date provides another perspective. The median publication date for the most banned books in America is 2012, still representing books published 15 years ago.

For a more comprehensive understanding, additional data points regarding the age and publication dates of these frequently targeted books are illuminating:

• Average Publication Year: 2008
• Median Publication Year: 2012
• Percentage of Books Published Before 2000: 35%
• Percentage of Books Published Between 2000-2010: 40%
• Percentage of Books Published After 2010: 25%

This data serves as a powerful tool for advocates seeking to promote inclusive and diverse library collections. It highlights how the current panic is manufactured and directed. The fact that books published in the late 1990s or early 2000s are now considered controversial, alongside newer works exploring complex themes, strongly suggests that the focus of the bigotry is on marginalized identities and contemporary social issues. The question arises: why, in 2026, is a book published in 1999 topping the list of most targeted titles? Why is a book published in 1962 suddenly causing alarm?

The answer, as suggested by critics, is that the objections are often fabricated or politically motivated. These books were not perceived as harmful when their current critics were in school. Furthermore, both older and newer books that address nuanced and important topics do so with a level of care, sensitivity, and safety that young readers can engage with in libraries, often more effectively than through other channels.

This movement often masquerades as a "parental rights" initiative, but critics argue it is an attempt to circumvent the necessary conversations parents should have with their children about diversity, inclusivity, and critical thinking. The underlying motivations, according to this perspective, may include an unwillingness to explain differing viewpoints on race, sexual orientation, or gender identity, or to acknowledge scientific consensus on issues like climate change. It is also seen as a way to avoid discussing complex societal issues, such as the protection of vulnerable individuals or changing social dynamics related to adolescent development.

A Call to Action and Continued Advocacy

The persistent attacks on books and libraries represent a significant challenge to intellectual freedom and equitable access to information. Young people, in particular, deserve access to a wide range of stories and perspectives that reflect the diverse world they inhabit.

In light of these ongoing challenges, a formal call is being issued for individuals to share their experiences of censorship, particularly concerning LGBTQ+ Pride materials in libraries during 2026. Reports can encompass preemptive cancellations, subtle forms of quiet censorship, or more overt removal actions throughout Pride month. Submissions can be made anonymously, and the reporting form is being shared widely. This initiative aims to document the ongoing impact of censorship and provide further data to support advocacy efforts.

The ongoing struggle for intellectual freedom in libraries and schools demands continued vigilance and active participation from communities nationwide. By understanding the data, the historical context, and the underlying motivations, advocates can more effectively defend the right to read and the vital role libraries play in fostering informed and engaged citizens.
