The UC Publication Management System scans many data sources to find your research output. When it finds multiple data sources of the same work -- for example in Crossref, arXiv, and Web of Science -- it merges them together using 


Sometimes the merging algorithm makes a mistake, and the UC Publication Management System incorrectly merges two publications together. You or your delegate can manually unmerge the two publications using the following steps. 



0. Log into your UC Publication Management System account at https://oapolicy.universityofcalifornia.edu . If you are assisting a colleague as their delegate, impersonate them to access their account. 


1. Navigate to the publications queue and find the publication with the incorrectly linked datasource. If there are too many publications to easily scan, use the filters on the right sidebar to filter by the publications title. "Baryon acoustic BOSS quasars" is used in the example below. 




2. Click the “Sources” tab at the bottom of the entry to view all of the linked data sources: 



3. In the example shown, two different articles were merged incorrectly due to similar titles and metadata. Scroll through the list and click the “split” icon to split or unmerge the incorrectly grouped data source: 



4. The system will display a confirmation message: 

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 incorrectly claimed publication 


6. In some cases, the incorrectly merged item was not authored by you. If it was pending, you can reject it by clicking the “Reject” icon. However if the article has already been claimed, click the three dots icon at the upper left of the item entry, then click “Reject”:
