These are more or less raw scans at 300DPI greyscale with minimal compression and so the files are of large size. The images have not been processed into a professional product. The originals are A4 size, which is larger than 8.5x11. No obvious watermarks, identifications, or protections have been applied to these files. The copyright on the original material expired long ago.
Guest are welcome to make improvements upon the work such as straightening them up or working further with the artifacts of the often-yellowed parchment. The high resolution images can be exported directly from the PDF files with various tools.
Webmasters are welcome to copy these and host them on their own websites. This activity will keep them free and continually available as various hobby sites come and go over time.
