Said reviewer Peter Rawlik: "Eckert's rules, scholarly style, and knowledge complement one another, and his work is done with such horrible intense love and logic that somewhere along the way it ceases to be flummery and becomes something more. What would seem an impossible task is achieved in a manner that not only entertains but also informs about the original work."
And: "...Fans of Philip Jose Farmer's Wold Newton stories and crossover fiction in general have good reason to celebrate. Win Scott Eckert's Crossovers should be viewed as an essential work of the metafictional canon with value to fans ans scholars alike, placing it next to such standard works as Jess Nevins's Encyclopedia of Fantastic Victoriana and Shadowmen by Jean-Marc and Randy Lofficier."
