Kolkata Boi Mela :- (Book Fair) The Calcutta Book Fair was held in 1976 for the first time. Since then, this mega event takes place every year in the last week of January. Its organizer is the 'Publishers & Book Sellers Guild'. It has an international flavour as participants come from all over the globe.

It has always been regarded with high esteem for its academic tradition and as a paradise for the connoisseurs of books. The annual book fair has intensified this obsession of Calcuttans and given birth to a 'book fair culture' in the entire state. The fair is multi-faceted and yields positive results. The visitors in the fair get the opportunity to learn and form a notion about the society, culture, economy and heritage of diverse nations and even different states of our own country, of whom, we are otherwise so ignorant and indifferent.

This enormous fair is generally held on a cover area of 200,000 sq. ft. En masse, it spreads over a total area of 800,000 sq. ft. One of the salient features of the fair is the huge ocean of people who come from all corners of the city and even from outside. The authorities try earnestly for an immaculate management of such a chaotic situation and effectively manoeuvre the mob-movement through out the fairground. They are all the more cautious in facilitating the movement of the crowd between the Territorial Army Ground and the smaller ground on Jawaharlal Nehru Road. Car-parking facilities are also available near the different gates.
