Boi Mela started merely as a book fair; but in course of time, it has evolved into a national cultural festival reflecting the cultural spirit of the modern Bengali nation. In addition to book sales, Bangla Academy organizes literary and cultural events every fair-day. Thousands of people gather to purchase books and spend time with the company of books and their authors with a patriotic zeal. There is no entry fee. Publishers of Bangladesh take year-long preparation to publish a huge number of books during this month.
