In 2012, the NYPL returned to Potion to create “Frankenstein: The Afterlife of Shelley’s Circle”, an exploration of Percy Blythe Shelley’s works and Mary Shelley’s seminal novel. In the app, users have unparalleled access to a treasure trove of digitized Frankenstein archives from the NYPL’s collections, providing a window into the genesis of Frankenstein and its influence across the twentieth century. In addition, the app provides users with a unique window into Shelley’s creative process by comparing digitizations of Shelley’s original handwritten manuscript against a transcript of the published edition.
