You can find journal articles and other material using databases. Journals are academic magazines that are published regularly. Some journals are focused on news and trade e.g. Eureka
Other journals publish original research. The most well regarded journals use a quality control procedure called peer-review. These are considered to contain material of the highest academic quality. An example of a peer-reviewed journal is:
Tire Science and Technology
Below is a list databases that are particularly relevant and useful for Engineering. More databases covering other subject areas can be found on this a-z list.
IEEE Xplore Digital Library
The Institute of Electrical and Electronics Engineers (IEEE) publish many of the top journals in the areas of computer science, electronic engineering and telecommunications. You can access fulltext of IEEE and Institution of Engineering and Technology (IET) conference papers, journal articles, and IEEE standards back to 1988.
SAE Mobilus
The full text of the Society of Automotive Engineers (SAE) Technical Papers from 1964 onwards and the full text of the SAE International Journals from 1998 onwards. Also includes access to the bibliographic details of other related automotive book, journal and magazine content.
SpringerLink
Full text access to over 2200 journals covering engineering, computing and mathematics as well as medical, health and life sciences. Includes 'Annals of Mathematics and Artificial Intelligence' and 'International Journal of Automotive Technology'.
Access is until the end of 2022.
ScienceDirect
ScienceDirect is a full text database from publisher Elsevier covering a range of science and engineering subjects. Includes the journals published by the SME (Society of Manufacturing Engineers) -- the Journal of Manufacturing Systems, Journal of Manufacturing Processes and Manufacturing Letters. Also covers highly cited electronic engineering titles such as Automatica, Progress in Quantum Electronics and Pattern Recognition and highly cited materials titles such as Materials Today and Progress in Materials Science.
Web of Science
Web of Science is a bibliographic database on a wide variety of interdisciplinary subjects including engineering, computing and mathematical subjects. There are some links to the full text via Oxford Brookes University subscriptions.
British standards online (BSOL)
Complete set of over 38,500 current, draft and historic British Standards, more than 16,000 of which are British Standards Institution (BSI) adopted European and International standards.
ACM Digital Library
Association of Computing Machinery (ACM) digital Library. A full text database covering journal articles, conference proceedings, magazines and technical newsletters on the subjects of computing and information technology. Some content for electronic engineering e.g ACM Journal on Emerging Technologies in Computing Systems.
Academic Search Complete
Academic Search Complete is a large interdisciplinary database which includes some engineering titles. Some articles are fulltext, others just abstracts (summaries) of the fulltext.
Business Source Complete
Business Source Complete is a large database that specialises in management, business and economics, though there is also some coverage of engineering, computing and mathematics. Some articles are fulltext, others are abstract (summary) only.
Emerald Insight
This database contains academic and theoretical articles on management and business, including business strategy and the environment and aspects of quality control. The database provides abstracts from 1969 onwards and the full text of many journal articles is available from 1989.
Google Scholar
Google Scholar contains bibliographic records for a huge range of information sources across the full spectrum of subjects, including those for engineering, computing and mathematical subjects. There is no full text in this database, only bibliographic information and sometimes links to an external website where you may, or may not, be able to get the full text of the information source through Oxford Brookes University subscriptions.
O'Reilly
A large collection of electronic books, videos and tutorials (Learning Paths). Although focussed on computing and information technology there is also material on electrical and electronics engineering, mechanical engineering, composites, business and project management. Also accessible via iOS and Android apps.
Sage Journals
SAGE contains journals from the Institution of Mechanical Engineers (IMechE) including their proceedings parts A - P covering a range of topics.
