Higher Dimensional Categories an illustrated guide book
This work gives an explanatory introduction to various definitions of higher dimensional category. The emphasis is on ideas rather than formalities; the aim is to shed light on the formalities by emphasising the intuitions that lead there. Covered topics are: Penon, Batanin and Leinster, Opetopic, Tamsamani and Simpson, Trimble and May.

As categorical dimension increases, constructions such as cylinders, cones, and suspensions are no longer functorial in the old sense. These notes extend higher categories to oriented and antioriented categories. Compositions there commute only up to a coherent interchange law.

This paper looks at diagrammatic category and keeps the language simple. It asks what diagrammatic is, how category fits, and what a student should notice. Count, size, and order in diagrammatic are compared with everyday numbers.
