工程索引(EI)的检索和使用Engineering Index（简称EI）是由美国工程信息中心制作的综合性工程技术检索数据库.Compendex是目前全球最全面的工程领域二次文献数据库，侧重提供应用科学和工程领域的文摘索引信息，涉及核技术、生物工程、交通运输、化学和工艺工程、照明和光学技术、农业工程和食品技术、计算机和数据处理、应用物理、电子和通信、控制工程、土木工程、机械工程、材料工程、石油、宇航、汽车工程以及这些领域的子学科。
其数据来源于5100种工程类期刊、会议论文集和技术报告，含700多万条记录，每年新增约25万条记录，可在网上检索1884年至今的文献。
1995年以来Ei又开发了称为“Village”的一系列产品，Engineering Village 2是其中的主要产品之一，该平台除了能检索Compendex（Ei网络版）外，还能检索INSPEC和NTIS等数据库。

简介Engineering Villageis a Web-based information service that offers a wide range of quality resources for information specialists, professionals, and researchers working in the applied science and engineering fields. Engineering Village features:Access to the top information resources in the applied science, technical and engineering fields: Compendexis the most comprehensive bibliographic database of engineering research available today, containing references and abstracts to over 5,000 engineering journals, conferences and technical reports. The broad subject areas of engineering and applied science are comprehensively represented. Coverage includes chemical and process engineering,computers and data processing, applied physics, electronics and communications, civil, mechanical and materials engineering, as well as narrower subtopics within all these major fields. Online coverage is from 1969 to the present. Around 250,000 new records are added to the database annually. Compendex is updated weekly to ensure access to critical developments in your field.Engineering Index Backfile within Compendexis available covering the information from the printed Engineering Index from 1884-1968. If your institution purchased the Backfile you will be able to search one Compendex database covering 130 years worth of engineering references. This will add about two million additional records to the database.Inspecis a bibliographic database concentrating on electrical and electronic engineering, physics, information technology, and computer and control systems. The database contains over 7 million bibliographic records taken from 3,500 scientific and technical journals and 1,500 conference proceedings. Online coverage is from 1969 to the present, and files are updated weekly.点击进入The National Technical Information Service (NTIS)is the premier source for accessing unclassified reports from influential U.S. and international government agencies. The database contains access to over two million critical citations from government departments such as NASA, the U.S. Department of Energy and the U.S. Department of Defense. The database is updated weekly. The NTIS database was created in 1964 but the material cited in it can date back as far as 1899.Referex Engineeringprovides access to the broadest and deepest available coverage of engineering reference titles in ebook format. Collections within engineering include topic areas Materials and Mechanical, Electronics and Electrical, and Chemical, Petrochemical and Process.CRC ENGnetBASEYour institution's add-on subscription to ENGnetBASE allows you access to some of the world's leading engineering handbooks published by CRC Press. As of October, 2003 ENGnetBASE has more than 190 titles available online with many more on the way as new books are published or updated.
