Blank date published?

[Emma]

Why do I not see the date published when I look at the list of books on my shelves (it shows as unknown for some) but when I click on the book to add it, it's already there....

Thank you

They may not have original publication dates entered. Feel free to link titles and someone will try to correct them.

ah I see. I can change it I just didn't realise that was the issue. Thank you :)
