This introductory chapter situates ensuing arguments about the relations
between mapping and temporality made by the contributors to this collection.
It deploys two cases: (1) the film Back to the Future, and (2) the rise of
digital mapping, to exemplify complex aspects of these relations and to
highlight the ways in which temporality, as well as space, makes a
difference in digital times. A grounding of temporal thinking is deployed to
explore the intellectual forces that underpin different ways authors in the
book reflect on time as against space in this context. A justification is
provided for the sectional layout into ephemerality/mobility, stitching
memories, and (in)formalising, and basic introductions to subsequent chapter
arguments are made.
