简介：目的:对常用的国外光盘文摘数据库进行药学文献覆盖率等比较研究,找出药学文的收载特点.方法:对德温特药学文摘(Derwentdrugfiles,DDF)、荷兰医学文摘(Embase,EMB)、国际药学文摘(Internationalpharmacyabstracts,IPA)、美国医学索引(Medline,MED)等数据库分别进行高引用率期刊的收载情况、特定课题检索,各数据库检索结果逐一比较.检索时段为1997～1999年.结果:从医院药学的六个学科领域汇总统计出引用频率高的期刊90种(覆盖了所有引文的95%).90种期刊在DDF、EMB、IPA、MED四个数据库中分别收载了60、78、37、78种,4个数据库均收载的期刊有23种.IPA收载的品种少,但有4种期刊独家收载.不同文摘数据库中收载同一期刊的论文数量不相同.特定课题检索中,有两个课题检索到4个数据库都收载的文献,大部分课题的文献被3个数据库同时收载.不同数据库收载的文献有一定差异.结论:各数据库收载文献是有选择的,应查阅所有的文摘数据库,才能保证药学信息的检全率.
