This release is version 1.0 (23 December 2021).

The viewer can be slow to load the images, so please be patient. We hope to be able to remedy this in a future release and make the images load faster.

 

The manuscript images in this edition were provided by the National Library of Russia at Saint Petersburg, who kindly granted us permission to publish the images openly online. Rather than release them as simple image files, we decided to facilitate their further use by publishing them using the IIIF API. The International Image Interoperability Framework, or IIIF, is an open standard for sharing digital images. These images can be immediately used on IIIF-compliant websites and with amenable tools.

For reasons of server space and bandwidth, this edition uses JPG files rather than the full-sized TIFF files provided by the Russian National Library. The TIFFs were converted into JPGs using the cross-platform image editor GIMP (GNU Image Manipulation Program), retaining the resolution and colour profile of the original images. The TIFF image files have also been released: see section 6 below.

 

This edition uses the open source image viewer Mirador, which was designed for viewing images that have IIIF APIs. The viewer is lightweight and can be readily customized by the user, using the controls in the grey sidepanel on the left edge of the viewer, and the controls at the top right corner of the window. Any and all changes made to the viewer by selecting these modificators are cancelled when the page is reloaded.

The image:

• The image can be panned (click and drag) and zoomed (scroll, type +/-, or use the zoom controls)

The windows:

• The sidebar inside the window can be toggled open and closed, and its place on the page can be changed from left (the default) to the right or the bottom of the window
• (NB it is possible to open multiple instances of the same sidebar, but just close extra ones by clicking on the X in the top right corner of the panel)
• The window can be expanded by clicking on the “Maximize window” icon in the top right corner of the window: this also hides the sidebar on the left side of the viewer
• By clicking on the “Window views & thumbnail display” icon in the top right corner of the window, the window can be turned into a gallery view of thumbnails; the thumbnail scroller can be moved to the side or turned off

The viewer:

• The viewer can be made full-screen by clicking on the “Full screen” icon in the middle of the grey sidebar on the left edge of the viewer
• Further resources can be added in their own windows in the viewer, including more instances of the current resource: click on the white plus [+] sign in a blue circle, in the top left corner of the viewer. Clicking on the X in the top right corner of the window will close that window.
• In the viewer, two windows are open by default. This is in order to allow the side-by-side comparison of two letters. You can also open further windows, there is no limit to their number.
• By clicking on the ellipsis […] in the grey sidebar on the left edge of the viewer, the workspace type can be changed to ‘elastic’, which allows drag-drop positioning of the windows. This may be useful if you are using a very large screen and want to look at many images at the same time

If you would like to download copies of the images, see section 6 below.

The image viewer can be seen below in embedded form. Please feel free to explore its settings. If you accidentally close all image windows, click on the plus [+] sign in the upper left corner of the viewer and then on the resource it suggests. Alternatively, reload this webpage.

Once again, the viewer can be slow to load the images, so please be patient. We hope to be able to remedy this in a future release and make the images load faster.

The TIFF files and JPG files will shortly be available on Zenodo, the open science repository associated with and run by CERN and OpenAIRE. There are 57 images in total. (Since the Mirador viewer works with static images, some of the images in the gallery are duplicates that have been cropped and rotated to make texts legible.) The TIFF images run to about 4.73 GB, and the converted JPG images come to about 451 MB. Both sets of images can be accessed and downloaded freely here:
