  The digital transformation of our societies and in particular information and
communication technologies have revolutionized how we generate, communicate,
and acquire information. Collective memory as a core and unifying force in our
societies has not been an exception among many societal concepts which have
been revolutionized through digital transformation. In this chapter, we have
distinguished between "the digitalized collective memory" and "collective
memory in the digital age". In addition to discussing these two main concepts,
we discuss how digital tools and trace data can open doorways into the study of
collective memory that is formed inside and outside of the digital space.
