  The notion of continuation is ubiquitous in many different areas of computer
science, including systems programming, programming languages, algorithmics,
semantics, logic, and constructive mathematics. In fact the concept of
continuation nicely realizes sophisticated control mechanisms, which are widely
used in a variety of applications. Since we cannot escape control features, it
becomes a challenge to provide them with sound reasoning principles.
  Indeed there is much research activity on understanding, representing, and
reasoning about elaborated non-local control structures, in particular in
declarative programming languages such as functional and logic languages. The
proceedings of the Workshop on Continuations 2015, held in London in April
2015, illustrate some of the afore mentioned topics and hopefully they will
inspire further research work on the subject.
