Goodreads Librarians Group discussion

Hi everyone, I’ve come across a few records that look like weird, and I’m wondering if others know how to handle them.

They have long product-style titles (like TV antennas or teeth whitening strips) but then end with the name of an actual book. For example:

TV Antenna Indoor... E Assim que Acaba: https://www.goodreads.com/book/show/2...

Teeth Whitening Strips 14 Treatments... Corte de Gelo e Estrelas: https://www.goodreads.com/book/show/2...

These entries also include ISBNs, but I can’t verify that the ISBNs are linked to real books.

Has anyone else seen this kind of thing? Are these safe to mark invalid, or is there a protocol we should follow when we find entries like this?

Thanks in advance!
