How to quickly delete unnecessary reference data in EndNote?

To efficiently remove unwanted references in EndNote, utilize its built-in tools for bulk management and duplicate identification. This process is feasible and significantly streamlines library maintenance. Key actions include accessing the "Library Cleanup" function under the "References" menu to identify records with empty fields or unused data types. Crucially, utilize the "Find Duplicates" tool with deterministic matching criteria on fields like DOI or PMID to ensure accurate duplicate detection. Always back up your EndNote library (.enl file and associated .Data folder) before performing any mass deletion to prevent irreversible data loss. Employ the "Search" panel to isolate specific subsets of records using terms or identifiers before deletion for targeted removal. The primary workflow involves: 1) Backing up the library, 2) Running "Library Cleanup" to flag empty/unused records and reviewing them manually, 3) Using "Find Duplicates" with consistent matching fields to identify redundant entries, and 4) Applying filters via Search to locate specific references needing removal. This method enhances workflow efficiency and guarantees library integrity.
