A series of old books, at first glance no different from other antiquarian publications, became the starting point for a strange and shocking study by librarian and journalist Megan Rosenbloom. Their main secret lay not in the content, but in the covers: they were made of human skin. Where did these books come from and who was behind their creation? For whose collections were anthropodermic publications made, and how many of them were made? In The Dark Archives, Megan Rosenbloom explains how she and a team of scientists, experts, and other librarians researched this dark topic and followed rumors to uncover the truth. This study is reminiscent of a detective story and a thriller, with the only difference being that everything described by Rosenbloom happened in reality.
