Google Scholar and Dimensions are free online databases that are very broad. Google scholar has full-text links to UC paid sources if you add UC as a Library link in the settings. Dimensions does not have full-text links to UC content but, like Google Scholar, it will link to content freely available online. If you find something you want to read in Dimensions that has no full-text link, you can always search for it in the Library's MultiSearch or Google Scholar to see if we have paid full-text access to it.
