Here are a few good books that I highly recommend to anybody interested in expanding his/her vision. I've left off the classics from Homer to Shakespeare to Tolstoi because they are so obviously worth reading. But these titles below the radar are worth reading. They don't deal specifically with public relations, but in one way on another they have something to offer on topics of communication, dialogue, interreligious/intercultural reconciliation, new perspectives, and other concepts very much complementary to the discipline of public relations.
