Hello,

Thank you for the suggestion, but I need more info. Is it this one:
https://www.worldcat.org/title/directory-of-overprinted-british-postal-orders/oclc/610163399&referer=brief_results

I need the author(s), publisher, city, year, edition, ISBN and ideally OCLC. If you have a photo of the cover I can also add it.

Best regards

This appeared in my library as well now, so I added the two volumes under reference name Gledhill#.
