Historically, digital archives have focused on textual comparison. The frequent inclusion of images in these archives necessitates the same options for images. The Image Comparison Tool Project will explore the creation of open-source software that lets users drag and drop images from across a digital archive’s holdings into a central canvas. From there, users can juxtapose, zoom, and compare data. The Wide, Wide World Digital Archive, which brings together the variant editions of Susan Warner’s novel, The Wide, Wide World, will serve as an ideal test bed for the tool because the archive concentrates on how publishers adapt texts by adding covers, illustrations, and ads. A flexible image comparison tool would consequently advance our understanding of The Wide, Wide World and other illustrated works with long publication histories. The Image Comparison Tool--to be developed by the HDW--will also benefit scholars in a variety of humanities disciplines who need to analyze multiple images.
