INIS Database on CD-ROM

The International Nuclear Information System is a decentralized information system co-ordinated by the International Atomic Energy Agency in Vienna, Austria. It is the world's leading information system on peaceful uses of nuclear science and technology. INIS maintains a database containing over 2 million bibliographic references and announces the availability of scientific literature published worldwide on the peaceful uses of nuclear energy. It also maintains a collection of full text non-conventional (grey) literature that would be difficult to obtain elsewhere.

Metadex
DIALOG OnDisc® METADEX/Materials Collection: Metals•Polymers•Ceramics and METADEX/Materials Collection Site Enhanced combine three comprehensive databases – METADEX, Engineered Materials Abstracts, and Materials Business File™ – with worldwide coverage offered from 1966 to the present. 
METADEX covers the science and technology of metals, from ore preparation to the finished product, including steel making and nonferrous alloy production, and much more.
Engineered Materials Abstracts covers worldwide technical literature on the applications and science of polymers, ceramics, and composites.
Materials Business File provides comprehensive business information on the world's materials industry, including new/competitive materials and processes, and news briefs.

Ei Compendex

Ei Compendex® Instant Access to the World's Foremost Engineering and Technology Titles DIALOG OnDisc® Ei Compendex®, provides worldwide coverage of significant applied engineering and technology literature. DIALOG OnDisc Ei Compendex® combines two Engineering Information Inc. publications, The Engineering Index and Engineering Meetings to provide the most comprehensive, multi-disciplinary engineering reference tool.

NTIS (National Technical Information Service)

NTIS abstracts unclassified public reports from government agencies including National Aeronautics and Space Administration (NASA), Department of Defence, Department of Energy, Environmental Protection Agency, Department of Transportation, the Department of Commerce and some 240 other government-related agencies.

INSPEC - Physics

INSPEC - the Quality Database for Physics, Electronics and Computing

INSPEC is the leading English-language bibliographic information service providing access to the world's scientific and technical literature in physics, electrical engineering, electronics, communications, control engineering, computers and computing, and information technology.
INSPEC was formed in 1967, based on the Science Abstracts service which has been provided by the Institution of Electrical Engineers since 1898. (A complete history of Science Abstracts is provided on our centenary website). Though based in the UK, its sales are worldwide with over 80 per cent exported. The INSPEC database, which lies at the centre of this service, dates back to 1969 and has a long-standing reputation for database quality.
