Retrieval approach
Very much, a total of more than 10 kinds of index content, users can according to the clues at hand, the use of these indexes to find the required information.
Since the 83rd edition of 1975, all of CA's abstracts and indexes have been computerized, and the reporting time difference has been reduced from 11 months to 3 months, with domestic journals and most English-language books being reported in CA within the same month. The Web version of SciFinder also allows users to find the latest records of the day. CA online database can provide readers with the means of machine inspection for searching, which greatly improves the efficiency of searching.
The above four points make people engaged in chemistry and those who need chemistry think that more than 90% of the basic work to open a so-called new field of chemistry can be found in CA. It is precisely because of this that CA attracts people's attention. Since CA includes 98% of the world's chemical literature, it must be the work of almost all authorities are included in CA. It is a chemical worker's dream to have CA query channels and skillfully query CA.
