Baidu Scholar (http://xueshu.baidu.com) was launched in June 2014. It is a free academic resource search platform of Baidu. It is dedicated to contributing resource retrieval technology and big data mining analysis capabilities to academic research and optimizing academic resources. By the end of 2018, Baidu Scholar included hundreds of thousands of academic websites with an index of over 400 million literature resources, thus providing free access to a huge amount of Chinese and foreign literature. For scholars working with Chinese subjects or limited to Chinese as their working language, Baidu is particularly useful. Note that the interface of Baidu Scholar is available only in Chinese.
