Insert footer 12 Early Access (EA) • Since 2017, we have been working with journal publishers content in Journal to expand indexing of journal content to include EA articles in the Web of Science Core Collection and InCites Citation Reports ™ Benchmark & Analytics. 2021 • There are no changes to EA articles other than being assigned a volume, an issue, and page information; they retain the same DOI and cited references. • Early Access will be introduced to the 2021 JCR release (2020 data) to more accurately reflect the dynamic citation environment of rapid online publication.
Look for Early Access articles • We are introducing EA to the 2021 JCR release using a on the Web of Science Blog phased, prospective approach Adding Early Access content to Journal Citation Reports: Choosing a prospective model Contact: [email protected]
