The UC Publication Management System scans many data sources, such as PubMed, Crossref, and Web of Science, to find your research output and merges their data based on shared identifiers, authors, and other metadata. If the merge is in error, you or your delegate can manually unmerge the incorrect record by "splitting" the sources.
1. Navigate to your claimed publications list and find the publication.
Tip: Use the title filter to go directly to the publication
2. Click the “Sources” tab at the bottom of the record to view all data sources:
3. Click the “split” icon 
to unmerge the incorrectly grouped data source:
4. The system will display a confirmation message at the top of your page:
The data sources are now unlinked. This will create two versions of the article: one for the published version, and one for the incorrectly merged data source.
5. If the incorrectly merged data source should be merged with another article that already has been claimed, see: Merge or resolve duplicate items in your claimed or pending list.
Reject the incorrectly claimed publication
6. When you split a source off a claimed publication, the incorrect version is automatically claimed. If you did not author the work or if it is a duplicate that you do not want in your list, you may reject it by clicking the three dots icon menu at the upper left of the item entry, then clicking “Reject”:
If you unmerge an eScholarship deposit then redeposit a new version, please contact eScholarship Suppport for assistance addressing the duplicate version.
