Library Stack is a new kind of archive and lending library: a virtual emulation of received library protocols for collecting, indexing, preserving and sharing. Objects in the collection are held in a durable repository for long-term access and bibliographically cataloged for discovery. By translating the protean publishing of the cultural sphere into institutional databases, Library Stack increases its visibility and contextualizes it within a wider landscape of thought, practice and publishing. Library Stack also works directly with artists and publishers to produce precisely these kinds of category-defying ebooks, videos and digital ephemera.
