 This book is dedicated to Ion Colojoara, one of the main contributors to the development of spectral theory in Banach spaces. It contains survey papers and a careful selection of research papers by Colojoara's colleagues, former students, and prominent researchers in the field. Topics include:  growth properties of resolvents
 positive definite operator measures and operatorvalued functions
 spectral spaces of bounded operators
 realization techniques for analytic functions of several variables
 perturbation theory and spectral resolutions in Krein spaces
 orthogonal polynomials in several noncommuting variables
 idempotent linear relations and generalized projection on Hilbert spaces
