Though a notable publisher of academic titles, HUP also tries to appeal to a general readership (http://www.hup.harvard.edu/insidehup/history.html). HUP also owns the Belknap imprint; Belknap is respected for its 'books of long-lasting importance, superior in scholarship and physical production, chosen whether or not they might be profitable'. HUP is also the American publisher of the Loeb Classical Library.
