Alexander Solzhenitsyn's call for the disbanding of the Soviet Union and the formation of a Russian state made up of the Slavic republics will soon be available around the world, his American publisher said yesterday. The 100-page manifesto, to be titled "How We Must Rebuild Russia," will be issued in this country by Farrar, Straus and Giroux no later than March.

"The translation has already begun for Japan, Italy, Germany and France," said the firm's president, Roger Straus. "We're all equally eager that his plan be worldwide as quickly as possible in order to influence the government."

Solzhenitsyn's essay, most of which was published Tuesday and Wednesday in two Soviet periodicals, urges the return of private property and the replacement of the Communist apparatus with locally elected governing bodies. It was the first written statement by the Nobel Prize winner since Soviet leader Mikhail Gorbachev instituted his glasnost and perestroika policies.

Straus said he was planning to publish 20,000 copies, mostly in paperback. "I think Solzhenitsyn has a considerable following here -- not only in the thinking community in the colleges and universities, but among the people who read editorials," he said. "It ain't going to appeal to the audience for Danielle Steel."
