In 1974 Puski bought a small bookshop in a run down state named Corvin in the Hungarian quarter in New York. In 1975 he established the Puski Publishing House, which, apart from authors of Magyar Elet, also published works by writers who were denied the chance to do so in Hungary for political reasons. The Puski-Corvin Hungarian Bookstore, which he exchanged for a larger premise in 1984, became an intellectual centre for Hungarians living in the West.
In 1989 he returned to Budapest. His bookshop on Krisztina Boulevard became the place where the works of the intellectual inheritors of folk literature could be found. The work of the founder was aided later by his sons, Laszlo and Istvan Puski, and then his grandsons, Attila and Csaba Puski. Since the establishment of the publishing company, it has published works by writers, historians and poets dealing with essential Hungarian issues. Their bookshop has all the volumes which deserve to be read from a Hungarian viewpoint.
