A magazine in the vanguard of President Mikhail S. Gorbachev's drive for greater openness has organized a "week of conscience" beginning Saturday to commemorate Soviets unjustly killed in the Stalin era.

Photographs, newspaper clippings, letters and other documents about some of the millions of Soviets imprisoned or killed in political repression stretching from the 1930s until the early 1950s will be exhibited in a Moscow club, the official Tass news agency said Tuesday.The exhibit was proposed by the weekly magazine Ogonyok, which has used its pages to publish stunning revelations about injustices committed during the 29-year rule of dictator Josef V. Stalin, including the discovery of a common grave in Minsk, Byelorussia, containing the remains of more than 100,000 Soviets shot as "enemies of the people" in the 1930s.

"The memorial will be the manifestation of the grief of the people for millions of their compatriots, unjustifiably repressed, and will mean their political rehabilitation," Tass quoted Ogonyok editor-in-chief Vitaly Korotich as saying.

He said the exhibit, to be held in a Moscow club, would also contribute to the greater democratization of Soviet life sought by Gorbachev and "enhance confidence of other countries in the initiatives of the Soviet state aimed at the creation of a non-violent world."

Gorbachev, Soviet leader since 1985, has called for a definitive break with the political terror and harsh central controls of the Stalin era, which he has blamed for tarnishing the name of socialism and the Soviet Union.

Feature films and documentaries about the tragic pages in Soviet history will also be shown during the exhibit, which lasts until Nov. 26. Tributes will be organized to Stalin's victims in which prominent Soviet artists, scientists, writers, diplomats and military men will take part.
