The book Samajtatwer Itibritya is written in Bengali language for the Bengali speaking students of Sociology and other related sub-disciplines in general. The dearth of synoptic view and precise presentation of the subject of Sociology lead to the publication of this book. It incorporates vast areas of Sociology i.e. fundamental concepts, thoughts and theories in nut-shell. This book will be helpful to the students of both the Honours and the General streams of Sociology and other social science disciplines along with Rural Development, Social Work etc. Most of the Universities in West Bengal have initiated short answer type questions in the syllabus of Sociology at the U.G. level examinations. The book will provide them appropriate guidelines in this respect. The book will be pertinent to students appearing for the School Service Commission Exam, West Bengal Civil Service Exam and Madrassa Board Exam in Sociology and other related disciplines.
