In a Human Library, "books" refer to the individuals who share their personal stories, experiences, and perspectives with participants. These individuals are often called "living books." Each living book has a unique story that challenges stereotypes, dispels misconceptions, or provides insights into a particular aspect of their identity or life. Living books can come from various backgrounds, representing diversity in terms of race, ethnicity, religion, gender, sexual orientation, disability, and other aspects of human experience. The idea is to create a library of human experiences that readers (participants) can "borrow" for a conversation, allowing for a direct and personal exchange of ideas and perspectives.
