The Accession Number Field

This field is used to identify the internal tracking number for references imported from online databases. For example, if you import a reference from Clarivate Web of Science, the Web of Science Unique Identifier number will be imported into this field; if you import a reference from PubMed, the PMID will be imported into this field.

This field is one of three than can be used in EndNote temporary citations in place of the EndNote record number. The other two fields are Label and Pages. You can find more information on this in Temporary Citations Preferences.

Note: Only one item can be imported into this field. This means if a record from an online database contains both a Web of Science Unique Identifier and a PMID, only one of them can be imported into the Accession Number field. The other identifier will likely be imported into the Notes field.
