You can find out the impact of an article, if that article has been cited. Only c50% of articles are cited in another article
You can check who is citing an article and reconstruct the development of ideas through time
You can also check how many times all the articles from an author has been cited
You can evaluate how important an article is cited by a high number of citations but you cannot tell the reasons why the article is cited
The number of times a paper is cited is not a measure of its actual quality.
Some tools that measure the impact data do not incorporate books.
Certain disciplines have low numbers of journals and usage.
One should compare journals or researchers within the same discipline.
Review articles are cited more often and can change results.
Self-citing may skew results. Authors often cite their own work but these can usually be excluded from the results
Once an article is published, different online tools keep track of the number of times this article is cited by other academic authors in their own articles
The number of times an article is cited can indicate how important it is in a particular field of study, or how controversial it is, or just how popular the topic is
Impact factor is useful but it should not be the only criteria used to evaluate the impact of the author
To find out how much impact a particular article has had, by showing which other authors based some work upon it or cited it as an example within their own papers.
To find out more about a field or topic; i.e. by reading the papers that cite a seminal work in that area.
To determine how much impact a particular author has had by looking at his/her total number of citations.
No system collects all the citations for each article
To get a comprehensive list of citations you will need to search multiple databases - particularly Scopus, Web of Science and Google Scholar
Search for citations to individual articles across each database
Export citations into EndNote
Remove duplicate citations
The list remaining should be of greater accuracy than citation rates for an article based on one database
