"High impact" scholarly journals are those which have a large number of individual articles that are cited frequently by other researchers. Journals that are designated as high impact are generally considered to be the most significant in their field. But a high impact designation is only one possible quality factor, as some fields just generally have lower impact scores, or, since the impact factor is at the journal level not the article level, it may not accurately reflect the quality at the article level.
"Highly cited" journal articles can also be found. These are articles, which after their publication, are cited in many, many other publications. Generally it is thought that good scholarship is highly cited, but something can be highly cited if is controversial, as well. This guide includes two tools that can give us information about the number of times an article has been cited since it's original publication: Web of Science and Google Scholar.
