The Institution of Engineering and Technology (IET), produces this global repository of science, engineering, and technology-focused content. It comprises more than 100,000 technical papers and around 5,000 book chapters from 1994 onwards. Approximately 450 new documents are added to the IET Digital Library each month.

This digital library is a resource for discovery and access to scientific and technical content published by the IEEE (Institute of Electrical and Electronics Engineers) and its publishing partners. It provides access to more than 3 million full text documents in electrical engineering, computer science, and electronics. It comprises over 160 journals; over 1,200 conference proceedings; more than 3,800 technical standards; over 1,000 e-books, and over 300 educational courses. Approximately 25,000 new documents are added to IEEE Xplore each month.

The series Lecture Notes in Computer Science (LNCS), including its subseries Lecture Notes in Artificial Intelligence (LNAI) and Lecture Notes in Bioinformatics (LNBI), has established itself as a medium for the publication of new developments in computer science and information technology research and teaching - quickly, informally, and at a high level.

SPIE e-books is a growing collection of titles from SPIE Press, the largest independent publisher of optics and photonics books. The collection includes all of the top SPIE Press monographs, reference works, field guides, tutorial texts, and Spotlight e-books to keep researchers current on the latest science and technology and advancing their own work.

Synthesis is an information service for the research, development, and educational communities in engineering and computer science. It combines authoritative content with digital delivery to create a product that is substantially more useful than traditional print or digital publications.
