There are three main ways to find the articles you need:
To view details of all our electronic journal subscriptions and find out which databases index them, use the Journal Titles List.
The eJournal Technical Communication provides access to full text articles from 1995 onwards through IngentaConnect.
The eJournal Intercom is indexed in Business Source Complete and Engineering Source but full text is only available until 2005. On Moodle, your tutors can link you to selected recent articles from Intercom thanks to a special agreement with the publisher.
Google Scholar is a good place to look if you can be specific about what you need.
