In the academic sphere, journal articles and conference proceedings are the standard unit of scientific communication.
Most of this information is not freely available, but rather only accessible through library subscriptions. One way to find and access information is to consult library databases called indexes to the literature.
There are several databases that specialize in different kinds of literature within engineering, aimed for different audiences.
Google Scholar also focuses on scholarly information, although it can be more difficult to limit by subject with that index. If you do use Google Scholar, you can create direct links to our library's subscriptions of online journals by configuring the Scholar preferences.
There are two main ways to search for journal articles, by subject and by tracing citations. The first two databases are subject indexes, while the last two are citation focused. Citation searching allows you to track the progress of ideas by seeing who cited particular articles.
