Article-level metrics aim to disaggregate the impact of an individual article's from the impact of the publication in which it appears. To that result, it is recommended that a combination of traditional citations count with altmetrics score be used instead of evaluating the value of an article based on the impact factor of the journal in which it is published.
Many databases are making available the citations counts for articles. However, these are not the absolute numbers because they are limited to the content indexed by the database.
Provides electronic, full text access to the back files to hundreds of scholarly periodicals in a variety of disciplines in humanities, arts and sciences, social sciences, and business. Coverage begins with the first issue of the journal. The latest issue available is determined by a moving wall. The moving wall represents the time period between the last issue available in JSTOR and the most recently published issue of a journal. It is specified by publishers in their license agreements with JSTOR, and generally ranges from three to five years.
