There are over 8000 SCI (Science Citation Index) publications in the ISI (Institute for Scientific Information) Web of Knowledge database system. However, the publications are too many and it is difficult for new authors to choose the most suitable journals or periodicals to submit their research fruits of high level. So, some valuable information about SCI publications is collected, and the corresponding database is established. The records from this database are classified and counted. The statistical results show that the SCI publications information system is helpful to authors to issue papers.
