This guide outlines:

1. Google Scholar metrics to measure journal impact
2. What are h5-index and h5-median
3. Locate the Top Journals by subject area
4. Locate h5-index for a journal title

• h-index of a publication is the largest number h such that at least h articles in that publication were cited at least h times each. For example, a publication with five articles cited by, respectively, 17, 9, 6, 3, and 2, has the h-index of 3.
• h-core of a publication is a set of top cited h articles from the publication. These are the articles that the h-index is based on. For example, the publication above has the h-core with three articles, those cited by 17, 9, and 6.
• h-median of a publication is the median of the citation counts in its h-core. For example, the h-median of the publication above is 9. The h-median is a measure of the distribution of citations to the articles in the h-core.

• h5-index is the h-index for articles published in the last 5 complete years. For example, h5-index for 2018 is the largest number h such that h articles published in 2013-2017 have at least h citations each.

             For example,

For 2018, h5-index  for Nature of 365 means that 365 articles published in Nature in 2013-2017 have received at least 365 citations each.

• h5-median for a publication is the median number of citations for the articles that make up its h5-index
