In recent years, it has become common for museums, libraries, and archives to publish images using the International Image Interoperability Framework (IIIF), an international framework for image sharing.

For publishing IIIF images, viewers such as Mirador and Universal Viewer are used.

https://projectmirador.org/

https://universalviewer.io/

In digital archive systems that adopt the latter Universal Viewer, you can often obtain a URL specifying a particular frame by appending “#?cv={image frame index}”.

Note that the index starts from 0, so to specify the 2nd frame, you would use 1.

Here is an example from the “Kyoto University Rare Materials Digital Archive”.

Here is an example from the “Doshisha University Digital Collection”.

In some cases, such as when the viewer has been customized, the above parameter may not be available, but I hope this serves as a useful reference for obtaining URLs for sharing images with specific frame numbers.
