Wanfang Data includes content and search options for both Chinese and English-language users, and although the content is subscription-based, users can still search the portal and view limited records through the Chinese version of the system. The portal gives users access to an impressive array of Chinese patent and non-patent literature, ranging from journal articles to company listings and industrial standards. Institutions can choose to subscribe to a variety of subject-specific collections, so administrators can tailor the accessible content of the portal to user needs.
