Epstein’s Black Book is a publicly published digitized archive of the personal address books and contact directories once maintained by convicted sex offender Jeffrey Epstein, listing names, phone numbers, emails, and addresses of hundreds of individuals he collected over years of networking. While being named in the book does not in itself indicate criminal activity, the collection has drawn attention for the breadth of the connections it preserves and has been used by researchers, journalists, and watchdogs examining Epstein’s social and financial networks. The site includes searchable listings of names as well as downloadable structured data from the books and related flight manifests linked to Epstein’s movements.
