Edited collections usually have relatively clear provenance. Most often they are brought to life by colleagues who are intrigued by an issue or a question; they then organize a conference (or a collection) around that theme and seek a publisher for the resulting collection. Such works are commonly marked by the putative expectations associated with an edited book: There is an attempt by the editors to present the unifying theme desired (if not demanded) by most university presses and the academic reviewers whose reports determine which way the thumbs go. Usually the editors attempt to herd the cats they have invited to participate—and ask that the contributors address unifying themes or take desired approaches. Even if the cats do no more than tip a ritual bow in the direction of the unifying theme, the editors normally use the introduction and conclusion to craft at least the appearance of unification.
