  In this review, we discuss recent progress in the explorations of topological
materials beyond topological insulators; specifically, we focus on topological
crystalline insulators and bulk topological superconductors. The basic
concepts, model Hamiltonians, and novel electronic properties of these new
topological materials are explained. The key role of symmetries that underlie
their topological properties is elucidated. Key issues in their materials
realizations are also discussed.
