Manicule is a standalone React/Redux web application for presenting unique printed books and manuscripts in digital facsimile. Built and designed by Liza Daly and Whitney Trettien with support from the Price Lab for Digital Humanities at the University of Pennsylvania, Manicule allows editors to build guided tours through a book, annotate the edges of interesting pages, categorize and color-code each page in the facsimile, and visualize the book’s structure.
