When the parish of St-Agapit was established in 1946, its first curate, Father Chartrand, donated his private collection of books to start a public library. It was first located in the rectory and later in the church basement.

It is not known exactly when this facility was turned over to laymen but records show that the books eventually found their way to the local of the Club Femina where the inexhaustible Annette Magnan offered the many services of the St-Eustache-sur-le-lac library until her death in the Fall of 1975. The Club Femina then decided to sell the books and moved to other premises. A group of concerned citizen decided to form a committee dedicated to the creation of a public library in Deux-Montagnes. The city finally agreed to buy the books and got involved with the rent. A large group of volunteers tackled a major clean-up and classification of all the books, while the committee kept pressuring city council and solicited grants to create an official public library.

This goal was finally achieved on January 12, 1978 when the city adopted a by-law establishing the Municipal Library of Deux-Montagnes. On March 1st of 1978 all books were moved to the new premises in the Community Center. The library services and collections then took a rapid expansion. Il was an instant success with the community. The space occupied by the library was increased from 2,000 to 6,000 square feet following a grant from the Ministère des Affaires Culturelles du Québec.

The modern renovated building was then computerized and continuously enhanced with new services. In 1997, Internet access is our landmark event and who knows what the future holds.

From its modest beginnings, the Deux-Montagnes library is still growing by leaps and bounds. Thanks are due to those pioneers who succeeded in making these riches available to us.
