Periodical is the main form, but sci is not limited to periodicals, but also can retrieve some academic conferences and patents. Sci is an internationally renowned authoritative academic retrieval tool.
The contents of retrieval include academic journals and various professional documents, all of which meet the standards all over the world, so sci includes many journals, but sci also has a certain professional focus, and sci focuses on science majors, so the journals and documents of science majors are the main contents of sci retrieval.
Journals retrieved by sci
Among the periodicals retrieved by sci, it should be noted that special issues, supplements and conference collections with limited recognition in China can also be retrieved in sci. In sci, the general special issue will be searched in full text, but the search types are different, which is generally useful. The probability that supplements are retrieved is much smaller, and most of them are not retrieved. If it is retrieved, the retrieval type is conference document type.
Therefore, there are many types of sci journals, and the scope involved is still very wide. Authors should search for suitable periodicals according to their own publishing needs, and pay more attention when using sci for literature retrieval.
