There is a reference to Ian Mulligan’s Book in The American Archivist Vol. 83, No. 1 Spring/Summer 2020. Here’s a quote from the pdf version of the article:
Two recently published books—one by Ian Milligan (2019) and one edited by Niels Brügger and Ralph Schroeder (2017)—provide essential guides to help answer the question of what web archives are by describing concrete, nonhypothetical examples of how social science and humanities researchers are using web archives today. For those who have participated in web archiving activity and pondered how the records would get used, and for those who are looking to get involved in web archiving but are not sure what it takes, these two books are essential reading.
