The book in hand presents an account of geographical features of Bihar under three broad segments: Geophysical, Economic and Socio-cultural. Each segment consists of varied topics accommodating ample and possible updated subject matters in each chapter. The book includes sixteen chapters, each with the specific geographical arena, that fulfil the academic needs of university-level academia in particular and intelligentsia in general. Since maps are the expression of surface features and their positions, and tables are the expression of a set of facts or figures systemically, they provide instant information to the readers. As the maps and tables are better tools to explain the geographical features, they have been used extensively in the book. The text in the book is thereby supplemented with thirty-five maps and sixty-six tables to bolster the literature.
