ADN publishes monographs and anthologies, edits a semi-annual journal, organizes conferences and seminars, hosts the national contest for unpublished diaries, the "Pieve Saverio Tutino Award" every year whereby in September 2015 it was at its 31st edition. It collaborates with institutions and autobiography archives at a European and international level.

The Arquivo dos Diários of Lisbon (AADD) aims to create a common, open and dynamic area where the memories of the people become the heritage of the History of Portugal and a booster for future endeavours. The AADD wants to gather the statements of a single country in the European scenario, characterized by the goal of breaking the barriers of the Atlantic making it a country of encounters and clashes of cultures that over the centuries have made of the Portuguese language a means of communication.

The AADD actively collaborates with public institutions and associations as part of the commemorations of the 40th anniversary of the Carnations Revolution, crucial moment in the recent history of Portugal and the common European history. The AADD wants to gather the stories that have made up the History of this country, certain that its carrying out a cultural and social function not only for Portugal and former colonies, but also for the memory of Europe and for what the Union will be in the near future.
