DuXiu is a search engine specializing in Chinese academic materials based on a huge database of full-texts and metadata on scholarly resources from the early the 1930s to the present in all subjects and formats including books, articles from periodicals, graduate theses and dissertations, and conference proceedings, etc. Due to copyright restrictions, readers have different levels of content access. Some documents can be seen directly online full-text, some have to be requested as document delivery rather than document downloading. For instance, users can preview first 20 pages and make online requests for a limited amount of contents from an item: no more than 50 pages of one book/time, or maximum 20% of the total number of pages/week, or maximum 1000 pages/month.Link is valid for 20 days.
