Magenta Spiral: I´m sorry but I did not find this one in English. It was published in Moskow (MIR 1979/1982) and Berlin.
The name of the authors is spelled differently in English: Strugatski or Strugatzki, Arkadi (or Arkady) and Boris.
I found one of their very famous books in English:
"Hard to be a God" (Daw Books, Inc. 1974)
Arkadi and Boris Strugatsky have been very popular und were frequently met with in Soviet scientific journals. They write stories and novels about robots or strangers from outer space, most of them with a fine sense of humour and at the time, when the Soviet Union ruled Eastern Europe, with more or less hidden criticism of the Soviet system.
Boris, born 1933, is an astronomer who was working at the computer laboratory of Pulkovo Observatory. Arkady, born 1925, is a linguist specializing in the Japanese, and also a translator and reviewer.
