It is hoped that the humble efforts made in the form of this book will assist in the accomplishment of exploratory as well as result-oriented research studies. The book is primarily targeted to serve as text book to Post Graduate, M.Phil. and Ph.d students of research methodology in all disciplines of various universities. The book seems to be designed specifically for those students who are newcomers to research, and who may have a basic barrier with regard to the subject. The areas covered in the book follow a simple-to-complex approach in terms of their discussion. Overall, this book clearly reflects the teaching experience of the author with this subject. The book can be of value to researchers by introducing some information on how to carry out reviews of literature and its importance in research. All possible efforts have been made to further enhance the usefulness of the book. The feedback received from different sources has been incorporated.
