GENERAL INFORMATION
Hybrid logic is a branch of modal logic in which it is possible to directly refer  to worlds/times/states or whatever the elements of the (Kripke) model are meant  to represent. Although they date back to the late 1960s, and have been  sporadically investigated ever since, it is only in the 1990s that work on them  really got into its stride.

It is easy to justify interest in hybrid logic on applied grounds, because of the  usefulness of the additional expressive power. For example, when reasoning about time one often wants to build up a series of assertions about what happens at a  particular instant, and standard modal formalisms do not allow this. What is less  obvious is that the route hybrid logic takes to overcome this problem often  actually improves the behaviour of the underlying modal formalism. For example,
it becomes far simpler to formulate modal tableau, resolution, and natural  deduction in hybrid logic, and completeness and interpolation results can be  proved of a generality that is not available in orthodox modal logic.

This special issue has its origin in the International Workshop on Hybrid Logic  (HyLo 2007), which was held 6-10 August in Dublin, Ireland as part of the  European Summer School in Logic, Language, and Information (ESSLLI 2007).  The HyLo 2007 workshop continued a series of previous workshops on hybrid logic.

TOPICS
Topics of interest include not only standard hybrid-logical machinery like  nominals, satisfaction operators, and the downarrow binder, but generally  extensions of modal logic that increase its expressive power.
