Strategies for Locating Articles Using Citations

Known Citation (Complete information)

1) Favorite short cut -->  Try searching for the article title in Google Scholar.

2) Search for the journal title in the eJournal finder.

3) Seach for the journal title OR the article title in UC Library Search.


Spotty Citation (About the Article)

Look for specific information such as author(s), journal in which the study was published, date of publication, unique words to describe the subject area.

  • If the journal name is given, use the eJournal finder to locate the journal. 
    • Note: This will only locate journals to which the UC Merced Library subscribes.
  • If the author and/or other topic information is given, trying searching a database using those terms. e.g. Google Scholar, UC Library Search (catalog), or Web of Science.

What is the Get It At UC Button?

Get it at UC connects you from a source citation to the resource.

You will be taken to UC Library Search where you can navigate to the full-text of the source OR initiate a request for the source through Interlibrary Loan (ILL).

The Get it at UC button will appear in many library databases. Use it to more easily locate or request the resources you need!

Get It At UC button

Note: During fall 2021, you may still see the UC-eLinks button instead of Get it at UC.  Both buttons are designed to connect you to information sources.
