In 1941 Ali opened a new office at Via Fratelli Gabba 5 but the bombardments of the following year forced the Foàs to leave Milan for Ivrea, where they worked with Adriano Olivetti on a plan for a new publishing house, Nuova Editrice Ivrea, until 1943 when Adriano Olivetti organised their escape to Switzerland.

Although greatly limited, in the final years of the conflict, the agency's work did not stop but continued from Viggiù, near to Varese, where Augusto's wife was staying.

As from the 1940s, Ali also started to represent Italian authors among the first few of which were Dino Buzzati and Pier Antonio Quarantotti Gambini. They were followed, immediately after the war, by others such as Romano Bilenchi, Oreste Del Buono, Giuseppe Patroni Griffi, Giuseppe Berto and Elsa Morante, authors who are still represented today by Ali.

With the war over, Augusto started to detach himself gradually from Ali's work but Luciano found great help in the young Erich Linder, an important figure in the agency's development. The year was 1946.

Just a few years after Augusto's death (in 1948), Luciano agreed to work for Einaudi and in 1951 moved to Turin, handing over management of the agency to Linder.

In just a few years, Linder transformed Ali into one of the largest and most important literary agencies in the world with a portfolio of thousands of Italian and foreign authors.

In order to accommodate a continually expanding business, in 1978 Ali moved to Via Manzoni 41 where Linder worked tirelessly and was always careful to reconcile literary creativity with commercial demands. He personally supervised his huge number of authors and established direct relations with all publishers. For thirty years he was the leading figure on the Italian publishing scene until his sudden death in 1983 at the tender age of 59.

His work was taken over by his son Dennis who, in 1988, sold the agency to Donatella Barbieri, former chairman of Frassinelli and general manager of Sperling & Kupfer, who left the publishing houses to take over Ali at a time when the publishing industry was undergoing a rapid and constant process of transformation.

The offices of Ali were firstly transferred to Via Fratelli Gabba 3 (quite coincidently next to the building where the agency had been based in the first few years of the war) and then to its current location at Via Valpetrosa 1, which already accommodated the agency's monumental archive with thousands of contracts recording a large chunk of the history of publishing and culture in the 20th century.

In 2008 Agenzia Letteraria Internazionale commemorated 110 years in business by opening a new chapter in its history with the arrival of Chiara Boroli, who comes from a family with a long publishing tradition and who has an extensive knowledge of the publishing world and is a huge fan of literature.

Her investment in the company creates a strong alliance with Donatella Barbieri which guarantees a bright future while retaining the style of tradition.
