In contemporary science outside purely theoretical physics collaboration is a way of life.An article with a dozen authors is the rule, not the exception.In scholarship within the humanities, by contrast, seldom does one encounter journal articles or rese monographs with more than one author.My scholarly collaboration with Alan Gross is thus somewhat unusual.It is even more unusual in that within the span of two decades, it has yielded four books published by university presses, with a fifth nearing a sixth in the planning stages.The books we have written together differ significantly, for the better, from what either of us could have produced alone.
