Asimov's Guide to Shakespeare: A Guide to Understanding and Enjoying the Works of Shakespeare
Shakespeare's genius is marked by his rare ability to appeal to theatergoers of all types and all levels of education.  But for most modern folks, the Greek and Roman mythology and history, let alone the history of England and the geography of sixteenth-century Europe that his works are laden with, are hardly within our grasp.  Isaac Asimov comes to making obscure issues clear to the layperson, selects key passages from 38 of the great bard's plays plus two of his narrative poems and, with the help of beautifully rendered maps an figures, illuminates us about their historical and mythological background.
