It was ecological (and, by luck, even millennial). The aim was to restore a reasonably high approximation of wholeness to the disaggregated fragments into which editors had systematically fractured Blake’s original works during more than a century of strenuous editorial efforts to render them, and him, more readable by making them more compatible with the habits and dominant institutions of modern culture
In this case "ecological" involves the restitution of fragments. Put another way, negotiating a difficult landscape -- a diaspora of text and images through coincidence and for the sake of making images more easily viewed and texts more easily read by divorcing them -- and bringing back some coherency.
