Anyone got more information on this?
Checked the ISBNs of the !t Books items,
the results show HarperCollins or It Books as publisher
As Badmoon said the three books listed under !t Books originate from HarperCollins.
Amazon and Goodreads have records for those three books and the publisher name is stated as It Books.
I'm pretty certain the credit was created in error.
I have done the honours and marked !t Books as a duplicate and transferred the books to It Books.
