archive Repository

Long-term storage of image files

This repository stores original image files of print editions of the Encyclopedia Britannica. We never modify these files. Instead, we copy select images to the ebnn/_images folder for active use. The repository also includes scans of additional Britannica editions, as well as alternate scans of production editions.

At over 1TB, the archive repository is quite large and is stored on an external hard disk drive that is available at any time.

Once you have selected any images you need for current production, copy the files from archive to the ebnn/_images folder.

eb03, eb07, eb09, eb11

These are the print edition folders containing all image files related to that edition. Each print edition folder includes two subfolders.
