This book investigates the fundamental principles and structures of model theory, a branch of mathematical logic concerned with the study of formal languages and their interpretations. It explores how mathematical structures can be represented and analyzed through the lens of formal systems, providing a rigorous framework for understanding mathematical truth and consistency. The work is authored by Wilfrid Hodges, a distinguished mathematician known for his contributions to logic and model theory.

As part of the Encyclopedia of Mathematics and its Applications, this volume is recognized as a comprehensive and authoritative treatment of model theory. Its depth and rigor make it a valuable resource for advanced students and researchers in mathematical logic and related fields. The work is expected to provide a thorough grounding in the subject, enabling readers to engage with complex theoretical problems.
