Acknowledgements in books always tease readers with their vagueness, their references so useless and anonymous that one frequently skips over them — despite the obvious importance they hold to the book’s authors — without so much as a second glance. Hence why it’s so interesting that Brandon McLean chose to think critically about these names in his new series, Acknowledgements. What happens when you match an unknown name to an unknown face? And more interestingly, how would different people differ in how they match up names and faces? One could practically write a thesis on this topic.
