h-index¹

This field displays the h-index count and is based on a list of publications ranked in descending order by the Times Cited count.

The h-index is indicated by an orange horizontal line going through the Year / Total Year columns. The number of items above this line, which is "h" have at least "h" citations. For example, an h-index of 20 means there are 20 items that have 20 citations or more. This metric is useful because it discounts the disproportionate weight of highly cited papers or papers that have not yet been cited.

Calculating the h-index Value - The h-index factor is based on the depth of years of your product subscription and your selected timespan. Items that do not appear on the Results page will not be factored into the calculation. If your subscription depth is 10 years, then the h-index value is based on this depth even though a particular author may have published articles more than 10 years ago. Moreover, the calculation only includes items in your product - books and articles in non-covered journals are not included.
