Locating empirical research and tracking citations
Using descriptors and cited references as search strategies
One way to narrow a search to obtain articles that contain primary research is to search Academic Search Complete using subject terms (combined with keywords) and cited references.
Here is an example using the subject term, Empirical Research and the keyword, tourism:

From a list of search results, the number of cited references is often given for a given article. Cited references are articles cited in the given article. These will also appear at the end of the article. By clicking on cited references, the list of the articles cited in the article is displayed (separately from the full text of the article). By checking the boxes next to articles in this list and then clicking on related records, a list of articles that share common citations is displayed.


And clicking on Times Cited in this Database, produces a sub-tab, Citing Articles, that lists the articles which cite the given article.
You can also search directly for cited references by clicking the Cited References tab. You can then enter the author or title for which you want to find citations. When an author is cited, the works written by that author are listed and then from that list, you can mark the articles for which you want to find Citing Articles that cite the checkmarked articles.
