美国工程信息公司(Ei)是世界上最大的工程信息提供者之一,其产品《工程索引》早已被国内科技界人士所熟知。Ei于1998年3月在中国推出该公司的获奖Internet服务--Engineering Information Village(简称EiVillage)。 Compendex是工程和应用科学领域里最权威的文摘索引数据库,提供了1969年至今的一千多万条文献记录,内容覆盖190种工程类学科,收录来自55个国家的超过5,600种期刊、商业杂志和会议录里的文章,每年新增记录约650,000条。目前,以大的专业范畴统计,该数据库中电气工程类文献约占35%;化学工程和土木工程类各占约15%,矿业类和机械工程类各占12%;其它工程相关学科约占11%。数据每周更新。目前我馆订购的是1969年以来的数据。 在Ei Village2新界面中,还提供了USPTO和Esp@cenet以及Scirus的链接。USPTO是美国专利商标局的网站,可以查询包含6000000多个美国专利的全文数据库,由此可检索到从1790年至最近几周所发布的专利全文。通过Esp@cenet可以检索欧洲各国家专利局及欧洲专利局(EPO)、世界知识产权组织(WIPO)和日本所登记的专利。Scirus 是迄今为止在因特网上最全面的科技专用搜索引擎,覆盖超过1.05亿个科技相关的网页。
最新2018年Ei Compendex收录出版物期刊目录(版本号:CPXSourceList_01012018)目前已经更新。经过雅诗论文网编辑比对,相对于17年最后一期目录,EI官方又审核拉黑了几十本期刊。查看这些刊物不难发现,在最近的刊期中文章数量大幅飙升(灌水),学术质量大幅下滑。在新收录的期刊方面:“CHINESE JRS on SERIALS LIST”中新增了5本国内刊物,这也是对国内期刊学术质量的肯定。近年来国内学者投稿数量增多,在选择刊物方面,也期望作者们多多留意。
