I strip the business Legal structure off (Inc, Ltd...)

I also use the Copyright page to locate the IMPRINT when possible
Baen Books, (actually, Baen logo has SF or Fantasy on some, so I do use those when obvious) and not not their distribution SS
And with the Randy Penguin buying up so many imprints, this is also why I prefer Imprint.
