Research in information studies engaged with the influence of platforms in archives and digital preservation (Acker & Flamm, 2021;Kriesberg & Acker, 2022), as well as how mass digitization has influenced the ways in which digital collections are now accessed (Thylstrup, 2019) and perceived by archivists (Acker & Brubaker, 2014;Lossin, 2017).
