The lab’s side-by-side manuscript-image reading tool
The Coviewer is the lab’s working surface for reading Beinecke MS 408 alongside its dated comparator manuscripts — a multi-pane image stage with zoom, pan, layered marks, and direct image / IIIF URL load against allowlisted holding-library archives. The internal research version is up and running on the lab side. A public iteration of that surface is in development. The screenshot below is the internal tool, kept here as a preview of what will land on this page.
