In updating the Norton Critical Edition of _Blake's Poetry and Designs_ (1979; 2008) to include the entire textual portion of _Jerusalem_, editors Mary Lynn Johnson and John E. Grant attempted to continue engaging and informing first-time readers of Blake within the constraints of the publisher's current editorial and fiscal policies. This anecdotal case history considers the influence of unforeseen contingencies and exigencies in book production upon high-minded editorial praxis. This essay appears in _Editing and Reading Blake_, a volume of _Romantic Circles Praxis Series_, prepared exclusively for Romantic Circles (http://www.rc.umd.edu/), University of Maryland.
