Another publishing giant has been caught blocking access to academic research in China.

Springer Nature, which claims to be the world's biggest publisher of academic books, has confirmed that it is restricting access to hundreds of articles that cover topics deemed sensitive to Chinese authorities.

The revelation, first reported by the Financial Times, comes just two months after Cambridge University Press reversed a decision to censor articles in China after a furious backlash from academics and activists.

Berlin-based Springer Nature, which is owned by the Holtzbrinck Publishing Group and private equity firm BC Partners, publishes about 3,000 journals. The company's stable includes Scientific American, a popular magazine whose history dates back 170 years.

An online search on the publisher's Journal of Chinese Political Science reveals that many research articles can't be viewed inside mainland China. Those blocked included politically sensitive keywords such as Tibet, Taiwan and Tiananmen. The articles do appear in searches from Hong Kong, a semi-autonomous Chinese city with its own legal system.

For example, a search from Beijing for articles containing Tiananmen yielded zero results. The same search from Hong Kong came back with 92 articles.

Some topics that didn't immediately appear sensitive were blocked too. A search for Xi Jinping, the Chinese president, didn't produce any results in mainland China. In Hong Kong, it yielded 78.

Other censored topics include the Cultural Revolution and Hong Kong, as well as disgraced former politician Bo Xilai and June 4, the date of the Tiananmen Square massacre.

A spokeswoman for Springer Nature told CNNMoney the company filtered its content in order to comply with Chinese law. She said that the decision was "deeply regrettable" but otherwise there was a "real risk of all of our content being blocked." Springer Nature estimates that about 1% of its academic content is affected.

Leading China academics have slammed Springer Nature's decision to censor some of its content in the world's second-biggest economy.

"This is hugely damaging to its reputation and standing as an academic publisher," said Professor Steve Tsang, director of the China Institute at SOAS University of London. "(This) is the thin end of the wedge that can cut academic freedom, and should not be accepted by the academic community."

Access to websites in China is heavily policed by the Communist government. Popular search engines and social media platforms including Google (GOOGL), Facebook (FB) and Twitter (TWTR) are all blocked using technology commonly known as The Great Firewall. Some popular Western news sites, such as the New York Times (NYT), are also unavailable.

Cambridge University Press, which describes itself as the oldest publishing house in the world, admitted in August to blocking online access in China to academic works about Tiananmen Square, the Cultural Revolution and Tibet.

The publisher reinstated access to the articles in its China Quarterly journal following an outcry in the academic world. The publisher had defended its action as necessary to ensure that China doesn't block "entire collections of content."
