SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

The Journal of the American Academy of Dermatology (JAAD), the official scientific publication of the American Academy of Dermatology (AAD), aims to satisfy the educational needs of the dermatology community. As the specialty's leading journal, JAAD features original, peer-reviewed articles emphasizing:
