From the NYT:

The independent Russian newspaper Novaya Gazeta on Wednesday officially began sales of a bound collection of articles and commentary by Anna Politkovskaya, its special correspondent who was killed last year, and renewed its demand for an honest investigation of the crime.  ...

The case, which is under investigation, is the latest in a line of killings of journalists in Russia that remain without resolution, and it has made her a posthumous symbol of the diminished media freedom here.

The collection of her work, a brick-thick volume of 980 pages, bore a photograph of her intent face beside a title of two words: “For What.”

Mikhail S. Gorbachev, the former Soviet president and a co-owner of the newspaper to which Ms. Politkovskaya brought fame, joined her editors, friends and family in calling for the crime to be solved.

He said the case was especially important because much of Russian society thought that law enforcement officials had been involved in her killing. Using words that did not criticize Mr. Putin directly, Mr. Gorbachev also spoke of Russia’s need for independent journalists.

“There is a great need for such people,” he said. “Maybe now the need is even greater than before.”

Mr. Gorbachev later held a copy of the book and suggested that while Ms. Politkovskaya’s writing was painful for some to read — it often accused government officials, soldiers and police officers of crimes — it was ultimately helpful to the Russian state.

“It is bitter,” he said. “But it is a medicine.”

Ms. Politkovskaya’s colleagues at Novaya Gazeta also spoke with frustration about the pace of the official investigation, saying they had cooperated with law enforcement agencies but had not seen a result.

They added that they had refrained from publishing materials their own work had turned up, because they did not want to endanger the official case or its sources of information. But they expressed worry that the official investigation would be whitewashed and said that if such a course became evident, they would be compelled to publish their findings.

“If we see the political resolution is about to be imposed, we will run all of the material that we have,” said Dmitri Muratov, the paper’s editor in chief.
