We believe that now is the opportune time to unify the theory of space bounded computations below log n with higher complexity classes. This needs to review the basic concepts of the space complexity theory and clarify the role of the space constructibility. Despite of the fact that the space below log n behaves radically different from the higher bounds, many important techniques do work on the both sides of this boundary. In addition, several important problems are closely related across the log n space bound.
