Many thanks, Pablo. That does indeed help. I now have the metadata that I want. And, as I have discovered, I will need to get PDFPen Pro to access more than just the Document info panel. Until then, I will rely on Acrobat Reader to ensure that it is available.

Very best, Alan

Hi Alan,

it seems that the key field cannot contain spaces. So it should read:

  \pdfbackendsetinfo{key}{ Text }

Otherwise, Acrobat Reader (both latest DC in Windows and version 9.5 in
Linux) cannot open the document.

And the information is displayed in the custom tab from document
properties, not in the description tab.

Here is an image of the dialog:

Acrobat Reader version 9.5 doesn’t contain that tab and it cannot
display the field.

I hope it helps now,

Pablo
