Articles published in the World Journal of Gastroenterology (WJG) have been cited by 361 SCI covered journals, 44.59% of which are journals in the USA and 3.60% in China. Authors from 484 institutions have cited WJG, in which 22.58% of them are in the USA and 18.84% in China. The highest impact factor of SCI journals that have cited WJG is 28.740 (Nature Medicine), with 52.95% (n=170) of journals with an impact factor over 2.0. The total citation times of articles published in WJG during 1998-2003 were 484. The total citation times in 2003 were 2736 with 73.24% (2004) self-citation, 1486 in 2002 with 94.27% (1401) self-citation, 537 in 2001 with 92.92% (499) self-citation, 238 in 2000 with 92.43% (220) self-citation and 24 in 1999 with 33.33% (8) self-citation. Articles published in WJG in 2002 were cited 85 times by other SCI covered journals, and 82 articles were cited. The number was increased to 372 and 332 for articles published in 2003, respectively, with increase rates of 337.64% and 304.87%, respectively. Authors who have cited WJG are from 37 countries, and the journals that have cited WJG are from 21 countries. A total of 1 020 (57.46%) articles published in WJG were supported by international or national grants. Authors of WJG articles are from 40 countries. Articles published in issues 5-12 in 2003 have been downloaded 53 476 times online. In 2002, WJG was awarded a special grant from National Natural Science Foundation of China. Generally, the percentage of the self-citation times of articles published in WJG declined from 94.27% in 2002 to 73.24% in 2003. Meanwhile, article numbers and times cited by other SCI covered journals rose to 304.87% and 337.64% respectively. The above data suggested that the WJG underwent rapid development in 2003 with a significant increase in both numbers of cited articles and times of citation.

World Journal of Gastroenterology (WJG ISSN-1007-9327) is an international academic journal in digestology published in China. The WJG was established in 1995 under the name of China National Journal of New Gastroenterology, and adapted its present title in 1998[1]. The WJG, now published semimonthly by the WJG Press, is a 210 mm × 297 mm-sized journal with 160 pages in each issue. The Journal is distributed by the Beijing Newspaper and Periodical Subscription and Distribution Bureau (Postal Issuance Code 82-261). In response to continuing growth in both basic and clinical studies on digestive diseases and the increasing demands for the international exchange in science and technology, the WJG will be published weekly from January 2005, with 160 pages in each issue. The publication dates are on the 7th, 14th, 21th and 28th of each month. Center for Information Analysis, Institute of Scientific and Technical Information of China conducted a general assessment on the SCI citation, source of manuscripts, and grant support of the articles published in the WJG during 1998-2004 (issues 1-6), based on the information from ISI SCI, ISI JCR and Citation Report of Chinese Journals of Science and Technology. The assessment report is as follows.
Articles published in WJG have been cited 5 021 times, of which the total citation times in 2003 were 2 736 with 73.24% (2004) self-citation, 1 486 in 2002 with 94.27% (1401) self-citation, 537 in 2001 with 92.92% (499) self-citation, 238 in 2000 with 92.43% (220) self-citation and 24 in 1999 with 33.33% (8) self-citation. Citations have been consistently increasing. However, the increase in self-citations is signifi-cantly lower than the increase in total citations (Figure 1).
Articles published in WJG in 2002 were cited by other SCI covered journals 85 times, and 82 articles were cited. The numbers were increased to 372 and 332 for articles published in 2003, respectively, with an increase rate of 338% and 305%, respectively (Figure 2, Table 1).
