Electronic journals are journals that exist in their full texts online.
Most of these electronic journals can be accessed through databases produced by the publishers of these journals. These are very convenient resources, but because they are limited to the publications of only one or two publishers, you will only be searching the information those publishers produce and not the full body of information on the subject. For this reason, traditional index databases like the ones listed above are still necessary for thorough research on a topic. An example of an electronic journal database is Elsevier's Science Direct.
