Literature gives pleasure and has been embraced by readers for ages. But just as the creator felt 'What have I uttered' after the first verse of literature was uttered from the mouth of Valmiki! Because the poetic verse was unfamiliar to him, similarly, as soon as the reader enjoys reading new literature, a question arises in his mind - 'What kind of work is this'? This book was launched in 1992 to fulfill that question. The age of world literature has passed thousands of years and the age of Bengali literature has also passed thousands. Not all writings are written in the same mold - poetry, drama, stories, novels, essays and many other types of writings - naturally, the style of each creation is different. This book describes the characteristics of all these categories of literature in simple language. Keeping in mind the needs of the reader, the eleventh edition is being published, expanding the topics of discussion considerably and highlighting the changes in time in each discussion.
