The above notice has been creeping its way into my listings. And today, it seems to be the default status of all my book listings. PLEASE NOTE: I sell primarily old science fiction and genre books. Most of the publishers are long gone, so there is no "brand owner." And many of the existing pages NEED EDITING. They are often pages created decades ago, and often lack proper descriptions or other details. I can't even add missing info like number of pages or format, etc.

I understand restrictions for in-print or back catalog titles for existing publishers. But for a 50 year-old magazine from a defunct publisher?

Editing privilege for such ASINs was, up to now, a primary benefit of a pro account. End of an era, I suppose.
