Top Journals/Citation Analysis
One way to help determine the importance of an article, author, or journal in the field is to analyze the number of times that an article, author, or journal is cited. The process for doing this is known as citation analysis. The idea is that if an article, author, or journal is highly cited by others, then it must be making an impact on the field. The most highly cited authors, articles, or journals are likely to be the top/most well known in their field.
Citation analysis is a standard practice, and it is widely accessible with tools such as GoogleScholar Metrics and Journal Citation Reports. However, the tools used in citation analysis all have limitations. Using multiple tools and comparing results can offer a better perspective of value within a field. Citation analysis should be a factor in determining value, but it should not be the sole factor. As scholars, it is important that we evaluate articles, authors, and journals on their own merit as appropriate.
When using citation analysis, it is important to note that the measurements are only meaningful within a given field. So comparing education related analysis to physics related analysis is not meaningful.
There are many measurements available, but the two most common are known as the impact factor and h-index.
The Impact Factor measures the influence of a journal in the field. It does this by calculating the number of times that articles published within that specific journal and within given years have been cited. Basically, an impact factor of 3.5 means that, on average, the articles published one to two years ago have been cited 3.5 times.
The h-index measures the influence of an author in the field. (Recently, variations of the h-index have been developed to measure other factors, so check the tool you are using to be sure about what your measurements are indicating.)
An h-index of 20 means that an author has 20 papers with at least 20 cites for each paper.
The h-index originated with J.E. Hirsch. Here's his article about it:
Before conducting a search, click on "metrics" in the menu above the GoogleScholar logo:
You'll see a list of top publications. You can also click on the search option in the upper right to type in a search and then also view a category.
GoogleScholar search results are weighted by word order, citation counts, and relevancy. Oftentimes, the first results are the most relevant and the highest cited works. However, it is best to try your search in a variety of ways, and it is best to use additional tools alongside GoogleScholar to ensure that you locate the most important articles on your topic.
