Not all libraries hold books. Some store seeds, genes, minerals, and code—collections that safeguard the essence of life itself. The Memory Keepers explores the new architecture of preservation: the global network of vaults, labs, and databases built to ensure that knowledge, biodiversity, and identity survive an uncertain future. This beautifully written book examines what it means to "remember" in an age when the world's most precious information isn't printed but frozen, sequenced, or stored in glass vials. Moving between science, philosophy, and design, The Memory Keepers reveals how humanity's oldest instinct—to save what matters—has evolved into one of its most sophisticated technologies.
