If scientific impact is considered related to the number of endorsements, in the form of citations, a journal receives, then prestige can be understood as a combination of the number of endorsements and the prestige or importance of the journals issuing them. The ''SJR indicator'' assigns different values to citations depending on the importance of the journals where they come from. This way, citations coming from highly important journals will be more valuable and hence will provide more prestige to the journals receiving them. The calculation of the ''SJR indicator'' is very similar to the ''[[Eigenfactor]] score'', with the former being based on the [[Scopus]] database and the latter on the [[Web of Science]] database.<ref>{{cite web | title=SCImago Journal & Country Rank (SJR) as an alternative to Thomson Reuters's Impact Factor and EigenFactor | url=http://www.scimagojr.com/news.php?id=41 | date=21 Aug 2008 | accessdate=20 September 2012 | archive-url = https://web.archive.org/web/20130426151143/http://www.scimagojr.com/news.php?id=41 | archive-date=2013-04-26 | url-status=dead}}</ref>, and there are other differences<ref>{{cite web | title=Network-based Citation Metrics: Eigenfactor vs. SJR | url=https://scholarlykitchen.sspnet.org/2015/07/28/network-based-citation-metrics-eigenfactor-vs-sjr/ | date=28 Jul 2015 | accessdate=26 Apr 2020 | archive-url = http://web.archive.org/web/20200426211041/https://scholarlykitchen.sspnet.org/2015/07/28/network-based-citation-metrics-eigenfactor-vs-sjr/ | archive-date=2020-04-26}}</ref>.
