Finding and eliminating duplicates

If you repeatedly run searches on the same topic in different databases, or if you are working on a project with other team members, it is virtually inevitable that you will end up with duplicates of references in your project.

Criteria for identification of duplicates

Citavi helps you find duplicates and remove the unnecessary information. The following criteria are considered:

• References with identical ISBNs, DOIs, PubMed IDs, or arXiv IDs will be identified as duplicates
• If the year of publication or edition vary, the referencea will not be identified as duplicates, even if an identifier was the same.
• For all other reference types or if the ISBN or accession number for a book is unique or missing, Citavi compares the name of the author, the title and the year of publication using the Levenshtein algorithm.

Searching for and Deleting Duplicates

1. In the Reference Editor, on the References menu, select Show duplicates only.
2. Citavi displays the duplicate references as a selection.
3. Compare the references and delete the duplicates you don't need.

Hint:

Table view is ideal for comparing, selecting, and deleting duplicates.
