OBJECTIVES
The research identified the publication types and ages most frequently cited in the infectious diseases literature and the most commonly cited journals.
METHODS
From 2008-2010, 5,056 articles in 5 infectious diseases journals cited 166,650 items. Two random samples were drawn: one (n = 1,060) from the total set of citations and one (n = 1,060) from the citations to journal articles. For each sample citation, publication type and date, age of cited item, and inclusion of uniform resource locator (URL) were collected. For each item in the cited journal articles sample, journal title, publication date, and age of the cited article were collected. Bradford zones were used for further analysis.
RESULTS
Journal articles (91%, n = 963) made up the bulk of cited items, followed by miscellaneous items (4.6%, n = 49). Dates of publication for cited items ranged from 1933-2010 (mean = 2001, mode = 2007). Over half (50.2%, n = 483) of cited journal articles were published within the previous 5 years. The journal article citations included 358 unique journal titles.
DISCUSSION
The citations to current and older publications in a range of disciplines, heavy citation of journals, and citation of miscellaneous and government documents revealed the depth and breadth of resources needed for the study of infectious diseases.
目的
本研究旨在确定传染病文献中最常被引用的出版类型和年代，以及最常被引用的期刊。
方法
在 2008 年至 2010 年间，5 种传染病期刊中的 5056 篇文章共引用了 166650 篇文献。从总的引文和期刊文章的引文这两组随机抽取了两个样本：一个（n=1060）和另一个（n=1060）。对于每个样本引文，记录了出版物类型和日期、被引文献的年龄以及统一资源定位符（URL）的包含情况。对于引用期刊文章样本中的每一篇文献，记录了期刊标题、出版日期和被引文章的年龄。采用布拉德福区带法进行进一步分析。
结果
期刊文章（91%，n=963）占被引文献的大部分，其次是杂项文献（4.6%，n=49）。被引文献的出版日期范围为 1933 年至 2010 年（平均 2001 年，模式 2007 年）。超过一半（50.2%，n=483）的被引期刊文章是在过去 5 年内发表的。期刊文章引文包括 358 个独特的期刊标题。
讨论
传染病研究需要广泛的资源，本研究揭示了当前和较旧出版物在多个学科中的引用、期刊的大量引用以及杂项和政府文件的引用，这表明了资源的深度和广度。
