Back in the good old days
of Paperbacks I would home in on Publishers IMPRINT (Logo or spine colors) because certain one tended to publish what (style, story theme ...) I liked best
There is a reason
Dragonlance appears prominently on their covers
Baen switched from the original BAEN in a keystone to the Dragon or Spaceship.
It allowed the customer to 'home in' quickly on the Fantasy or Science Fiction genere offerings
IMPRINT sells books, not the (big) Publishers name
