The #WeNeedDiverseBooks meme originated from a 2014 social media campaign launched by authors to address the lack of diversity in children's literature. While the movement itself is a serious grassroots organization, the hashtag evolved into a meme format where users hold signs or use the slogan to highlight specific, often niche or humorous, needs for representation in media. It transitioned from a pure activism tool into a widely recognized template for book lovers to express their desires for certain tropes, characters, or cultural backgrounds to be featured more prominently on library shelves. Today, it remains a powerful blend of advocacy and online cultural expression used across Twitter, Instagram, and TikTok.
