Staff-less public libraries, enabled by technological developments, represent a significant and innovative aspect of the development of public libraries. The concept radically enlarges the availability of user access to public libraries. Some Danish public library branches have, for example, increased their weekly opening hours from 20 to 80 hours per week. In Denmark, the concept has been quite successful, increasing the number of staff-less libraries from 81 public library units in 2011 to 260 in 2014.

From a longer view, however, the staff-less library concept contributes to the modernization of public libraries by further opening the library. Many library professionals have been surprised by the near absence of vandalism through the staffl-ess opening hours. According to the latest trend, the staffless library model is gradually moving from thinly populated rural areas and suburban neighborhoods to urban contexts. This book explores the concept, hence furthering the debate.
