The Rise of Marginalia: Annotating Books Becomes a Trend on BookTok

In recent years, the literary landscape has witnessed a remarkable shift as the art of annotating books has transitioned from a once frowned-upon practice to a celebrated trend among readers, particularly within the BookTok community. This evolution raises questions about the motivations behind this resurgence and its implications for reading culture.

Traditionally, marginalia — the practice of writing notes and comments in the margins of books — was viewed as an act that detracted from a book's pristine condition. Many avid readers would vehemently oppose any markings on their beloved volumes, opting instead for immaculate, untouched copies. However, the advent of social media platforms like TikTok and Instagram has sparked a resurgence of interest in this practice, transforming it into a vibrant subculture within the broader literary community.

As of June 2025, according to a survey conducted by the Pew Research Center, approximately 43% of younger readers (ages 18-29) reported engaging in some form of book annotation, a significant increase from previous years (Pew Research Center, 2025). This trend is particularly pronounced among fans of romance and young adult genres, where communities thrive on sharing their annotated experiences. “I keep seeing people who have books like this,” notes a TikTok user in a video showcasing heavily annotated novels. “What are you doing? Explain yourselves! Because this looks like homework. But also … I do like office supplies.”

The practice of annotating books is not merely a superficial trend; it has deeper significance for many readers. Marcela, a Melbourne-based Bookstagrammer who goes by the handle @booksta.babe, began annotating her books to enhance her reading experience. “It has really helped me enjoy the rich world-building and character development even more,” she states, highlighting the personal connection she develops with the texts. Her method includes using color-coded tabs and pens to mark significant moments within the narratives, allowing her to revisit her thoughts and reactions during her initial reading.

This renaissance of marginalia can also be attributed to the changing perceptions of romance literature, particularly among younger audiences. Dr. Jodi McAlister, a noted academic in the field of literary studies and author of "An Academic Affair" (2023), argues that the mainstream success of authors like Emily Henry and Sarah J. Maas has helped dismantle the stigma surrounding romance novels. “What they’re doing is performatively turning it into this incredibly treasured, incredibly valued object,” McAlister explains. Annotating books allows readers to memorialize their experiences, transforming each volume into a personal artifact that reflects their journey through the story.

Moreover, the act of gifting annotated books has emerged as a popular trend within the BookTok community. Many users opt to annotate copies of their favorite novels as personal presents for friends, embedding their thoughts and reactions into the margins. This practice not only enhances the emotional connection between the giver and receiver but also creates a tangible link to the shared experience of reading.

However, the rise of marginalia is not without its detractors. Some traditionalists argue that the practice detracts from the integrity of the book as a physical object. Critics contend that marking a book can diminish its value, especially in an age where collectors seek pristine editions. Yet, the growing acceptance of marginalia suggests a shift in perspective, where the value of a book is increasingly perceived through its narrative and emotional connections, rather than just its physical condition.

In conclusion, the trend of annotating books signifies a broader cultural shift in how readers engage with literature. As digital platforms continue to foster communities that celebrate reading, the practice of marginalia may become a permanent fixture in the literary landscape. Future implications of this trend could reshape publishing practices, influence how books are marketed, and encourage deeper connections between readers and texts. As readers continue to explore their identities through the act of annotation, the boundaries of what it means to engage with literature are being redefined, paving the way for a richer, more interactive reading experience.
