Our project enhances the accessibility of ancient manuscripts and provide new ways of working with them. More precisely, we aim to produce a software tool allowing historians, and more particularly codicologists and philologists, to read manuscripts, write annotations, and navigate between the words of the transcription and the matching piece of image in the numerized picture of the manuscript. In this paper, we present the design of such a Hypermedia Workstation. It is based on the standardized hypermedia language HyTime.
