Search for references
The search for references is particularly useful because it allows you becomes aware of any studies that could not find through your research.
Pay attention to the references that appear at the end of articles and that you consider relevant and useful. Doing that can help you getting relevant results unobtainable from any other method.
This research method allows you to not only become aware of other studies / articles, but also to collect information about authors, keywords and leading publications.
Sometimes, an article has a link “cited by” allowing you to make the historic of citations of that article and access to information thus equally relevant to your research.
The ‘key’ articles may never have been cited, however, many of the current databases allow you to create alerts and be informed when those are cited.
Another way to search is to use the functionality related references by accessing related documents / records / articles . This function allows you to access documents that share at least one quote in common with the document you refer. This is also a good way to get relevant results.
