This book provides foundational background for advanced study in higher category theory, focusing on motivations and key structures. It begins with an exploration of how algebraic topology tools are viewed through the lens of n-category theory, followed by surveys of (infinity,1)-categories and the algebraic modeling of homotopy n-types. The primary emphasis is placed on the theory of bicategories, which serves as a crucial starting point for understanding more complex higher categorical structures. The book also includes discussions on gerbes in differential geometry and the historical development of category theory in Australia.

This collection of articles serves as a preparatory text for those interested in higher category theory, offering insights into its motivations and fundamental concepts. The inclusion of survey articles on well-understood areas like (infinity,1)-categories and homotopy n-types, alongside a detailed look at bicategories, suggests a structured approach to introducing complex topics. The book's dedication to Max Kelly and the inclusion of historical context indicate an appreciation for the field's development. The diverse range of topics, from algebraic topology to differential geometry, points to a broad yet focused exploration of higher categorical structures.
