How to find and delete duplicate literature in Mendeley?

Finding and removing duplicate entries in Mendeley is straightforward using its built-in duplicate detection tool. This process is effectively supported by the software's functionality. Mendeley identifies duplicates primarily by comparing title, author, and publication year information, while allowing user configuration during the check. It is critical to manually review proposed matches before deletion to prevent accidental removal of unique records with minor metadata variations, especially ensuring no duplicates are cited within active documents to avoid reference manager conflicts. Detection accuracy depends on consistent metadata quality across entries. Initiate the process by selecting "Tools" > "Check for Duplicates" and choosing the library or folder scope. Mendeley presents grouped suspected duplicates; expand each group, review entries, select the records to delete using the checkbox, and choose "Delete Selected References". Regularly performing this action maintains a streamlined, accurate, and efficient reference library, crucial for citation management and preventing redundancy in bibliographies.
