【目的】调查SSCI收录图书情报学期刊论文的被引峰值年代及其影响因素,为了解国外期刊论文被引峰值年代提供参考资料。【方法】以2004年SSCI收录53种图书情报学期刊为研究对象,调查2003年、2004年、2005年发表论文的被引峰值年代,并观察不同出版周期、出版语种、出版国家及不同文献计量学指标的期刊被引年峰值年代的差异。【结果】SSCI收录53种图书情报学期刊2003—2005年发表论文的被引峰值年代分别为发表后(5.4±2.4)年、(4.6±1.8)年、(4.0±2.0)年,被引峰值年代随时间发展逐渐提前,不同国别、不同出版周期及不同文献计量学指标SSCI收录图书情报学期刊的被引峰值年代不同;出版语种对被引峰值年代可能无明显影响。【结论】网络环境下,国外期刊论文被引峰值延迟,而期刊出版国家、出版周期及文献计量学指标对期刊论文被引峰值时间有一定影响。
【Objective】 The purpose of this study is to investigate the cited peak times of SSCI journals and their influential factors, and to provide reference materials for understanding the cited peak period of foreign journal articles. 【Method】 A total of 53 Journals of Library and Information Service were collected by SSCI in 2004 as the research object. The papers cited in 2003, 2004 and 2005 were cited and the peak periods of the cited papers were observed. And different publication cycles, published languages, published countries and different documents were measured Differences in the index periodicals from the peak years of their citation. 【Result】 The results of the cited citations of 53 Journals published in Library and Information Science from 2003 to 2005 were (5.4 ± 2.4) years, (4.6 ± 1.8) years, (4.0 ± 2.0) years, The development of the period gradually advances with time. The cited peak times of journals of library and information science in different countries, different publication cycles and different bibliometrics are different; the published languages may have no obvious influence on the cited peak years. 【Conclusion】 Under the network environment, the number of journal articles cited in foreign countries is delayed. However, the publication period, publication period and bibliometrics of periodical journals have a certain impact on the lead time of journal articles.
