Reply To: Publisher not identified
I would say that the name "Houghton Mifflin Harcourt" on the back left bottom of the cover is the publisher name (which also agrees with the HMH in the title). I do not see a city/state to apply to that, so I would use the Orlando, Florida address in the copyright info. You could also say there is no city/state associated with the publisher name and leave that area blank.
