Google 推出的免费学术搜索工具,可以帮助用户快速查找学术资料,包括来自学术着作出版商、专业性社团、预印本、各大学及其他学术组织的经同行评论的文章、论文、图书、摘要和技术报告。Google Scholar 是目前最好用的学术搜索工具。


从2010年8月28日起,ScienceDirect、Scopus 以及 Scirus 的特定网页内容已整合到一个称为 SciVerse 的平台中。那么,SciVerse是什么呢?概括起来讲,就是海量科研信息的一个一站式集散平台。这个平台,将帮助科研人员实现“少量搜索,更多信息”,而且,这些信息都是与科研相关的信息。就像文章题目所显示的那样,SciVerse整合了包括SD、Scopus以及Scirus的信息,形成一个“SciVerse Hub”(SciVerse中心)。除此之外,SD用户以及Scopus用户依然可以享受之前的服务,它们将与“SciVerse Hub”一起形成SciVerse的三大部分“SciVerse ScienceDirect”、“SciVerse Scopus”、“SciVerse Hub”,如下图所示:


Web of Science是美国Thomson Scientific(汤姆森科技信息集团)基于WEB开发的产品,是大型综合性、多学科、核心期刊引文索引数据库,包括三大引文数据库(科学引文索引(Science Citation Index,简称SCI)、社会科学引文索引(Social Sciences Citation Index,简称SSCI)和艺术与人文科学引文索引(Arts & Humanities Citation Index,简称A&HCI))和两个化学信息事实型数据库(Current Chemical Reactions,简称CCR和Index Chemicus,简称IC),以及科学引文检索扩展版(Science Ciation Index Expanded,SCIE)、科技会议文献引文索引(Conference Proceedings Citation Idex-Science,CPCI-S)和社会科学以及人文科学会议文献引文索引(Conference Proceedings Citation index-Social Science&Humanalities,CPCI-SSH)三个引文数据库,以ISI Web of Knowledge作为检索平台。


ResearchIndex 又名CiteSeer ,是NEC 研究院在自动引文索引Autonomous Citation Indexing ,ACI 机制基础上建设的一个学术论文数字图书馆,它提供了一种通过引文链接检索文献的方式,目标是从多个方面促进学术文献的传播与反馈。

ResearchIndex 检索互联网上Postscript 和PDF 文件格式的学术论文。目前在其数据库中可检索到超过500000 篇论文。主要涉及计 算机科学领域,涉及的主题包括互联网分析与检索、数字图书馆与引文索引、机器学习、神经网络、语音识别、人脸识别、元搜索引擎、音频/ 音乐等。 ResearchIndex 在网上提供完全免费的服务包括下载PS 或PDF 格式的全文,系统已实现全天24 小时实时更新。


Intute 是一个免费、便捷、强劲的搜索工具,由英国高等教育资助理事会下的信息系统联合委员会JISC 和艺术与人文研究委员会AHRC 开发建 立,专注于教学、研究方面的网络资源。所收录的信息资源都是经过行业专家选择和评审的,从而保证了其质量。目前数据库信息已达120060 条。

Intute 共设四大领域:科学与技术、艺术与人文、社会科学、健康与生命科学。各个领域下又包含诸多学科,以科学与技术类为例,覆盖了天文、化学、物理、工程、计算、地理、数学、地球科学、环境以及交叉学科,信息达33806 条。


INFOMINE 是为大学教师、学生和研究人员建立的网络学术资源虚拟图书馆。它建于1994 年,由加利福尼亚大学、威克福斯特大学、加利福尼亚州立大 学、底特律- 麦西大学等多家大学或学院的图书馆联合建立。它拥有电子期刊、电子图书、公告栏、邮件列表、图书馆在线目录、研究人员人名录,以及其他类型的 信息资源40000 多个。INFOMINE 对所有用户免费开放,但是它提供的资源站点并不都是免费的,能否免费使用,取决于用户所在图书馆是否拥有该资源 的使用权。


OAIster 是密歇根大学开发维护的一个优秀的开放存取搜索引擎,收集了来自536 家学术机构的590 万篇文档,包括开放使用期刊的文章、工作论文、讨论文章、会议论文和学位论文。可按关键词、题名、创作者、主题或资源类型进行检索。检索结果含资源描述和该资源链接。


Information Bridge 是由美国能源部DOE 下属的科学与技术信息办公室OSTI 开发维护的搜索工具,提供美国能源部1994 年以来研究成果的全文文献和目 录索引,涉及的学科领域包括物理、化学、材料、生物、环境科学、能源技术、工程、计算机与情报科学和可再生能源等。检索功能有基本检索和高级检索两种。


Information Find Articles 提供多种顶极刊物的上千万篇论文,涵盖艺术与娱乐、汽车、商业与经融、计算机与技术、健康与健身、新闻与社会、科学教育、体育等各个方面的内容,大部分为免费全文资料,检索操作简单。


BASE是德国比勒费尔德(Bielefeld)大学图书馆开发的一个多学科的学术搜索引擎,提供对全球异构学术资源的集成检索服务。它整合了德国比勒费尔德大学图书馆的图书馆目录和大约160 个开放资源(超过200 万个文档)的数据。


Vascoda是一个交叉学科门户网站的原型,它注重特定主题的聚合,集成了图书馆的收藏、文献数据库和附加的学术内容。


OJOSE (Online Journal Search Engine,在线期刊搜索引擎)是一个强大的免费科学搜索引擎,通过OJOSE,你能查找、下载或购买到近60个数据库的资源。但是感觉操作比较复杂。


为了给读者用户提供一个方便快捷的查阅国外各类期刊文献的综合网络平台,中图公司组织开发了cnpLINKer(cnpiec LINK service)在线数据库检索系统,并正式开通运行。cnpLINKer即“中图链接服务”,目前主要提供约3600种国外期刊的目次和文摘的查询检索、电子全文链接及期刊国内馆藏查询功能.并时时与国外出版社保持数据内容的一致性和最新性。
