99 out of 100 published letters were written between 1952 and 1961 and are especially rich in literary material. One of the main topics is the fate of the journal “Experiments”, where Ivask was first one of the closest employees, and then the editor-in-chief. Adamovich wanted to see the magazine as the best publication of Russian emigration, which in the 1950s would be able to maintain the highest level of intellectual culture. The internal affairs of the journal are discussed in detail: the circle of real and potential authors, plans for new sections, searches for patrons. The introductory article and detailed commentary provide a lot of additional information about the mentioned persons, works and events. Preface, publication and comments by N.A. Bogomolov. From the book Diaspora: New materials. Issue V. St. Petersburg, 2003. pp. 402–557.
