Since the start of the project, digital images of selected pages have been added to the title images to provide better information and make it easier to differentiate between editions.
Which pages do you usually find for a print?

• Title pages
• Pages with names of dedicatees
• Beginning of the main part
• Colophon
• Printer's mark

In the case of very small prints (approx. 4 pages), all pages become key pages.

The image pages have not been post-processed. The quality can therefore vary greatly. If printed in red, legibility may be impaired. The digitized pages are not intended as facsimiles, but should provide more information about the print, e.g. the complete titles or personal details of dedication recipients. This should also make it easier to identify editions.
The digitization was generally carried out with one-bit colour depth (bitonal) and a resolution of 150-300 dpi.
The annotations in the title records indicate from which copy the key pages were scanned.
