René Daumal’s allegorical adventure novel
Mount Analogue. He saw small-format books such as Daumal's as a kind of "anti-iphone." In November 2020, Isolarii published
F Letter: New Russian Feminist Poetry, which emerged as a symbol for anti-government protests in Russia. In 2021, Isolarii released
Street Cop, a collaborative work by
Robert Coover and
Art Spiegelman. The release received acclaim from
NPR, and was described by
The New York Times as a "palm-sized lark." In 2022, "The War Diary of Yevgenia Belorusets" marked Isolarii's debut in digital reportage. Co-published with
Der Spiegel, it was translated daily into various languages. It was adapted into a podcast episode for
This American Life and, on March 3, 2023, was cited by German Chancellor
Olaf Scholz when announcing changes to Germany's military support for Ukraine. It was later published in print as part of the volume
In The Face of War. As an afterword, photographer
Nan Goldin officiated a marriage between artists
Nikita Kadan and
Anti Gonna. ==Critical response==
