Realizability: An Introduction to its Categorical Side: Volume 152 by Jaap van Oosten (Utrecht University, The Netherlands)
Aimed at starting researchers in the field, Realizability gives a rigorous, yet reasonable introduction to the basic concepts of a field which has passed several successive phases of abstraction. Material from previously unpublished sources such as Ph.D. theses, unpublished papers, etc. has been molded into one comprehensive presentation of the subject area.
