The increasingly popular smartphones change not only how we read, but also where we read. Reading on the go is not new as the printed book has long been a treasured item for entertainment during travel (Marshall 2010). Still the digitization of texts and the introduction of smartphones with reading-quality screens creates a new situation where we potentially have constant access to all kinds of reading materials. This development forms the backdrop of our survey study, conducted in Denmark in Winter 2016/2017 among library professionals and Library and Information Science students.
