Using the OCA Proxy

When should I use the OCA Proxy instead of VPN?


What do I need in order to use OCA?

  • Your activated library card
  • Your library barcode number
  • Your last name (include any suffixes like “Jr.” etc.)


How do I activate my library card?


What is my library barcode number?

  • Your barcode number is on your Student or Staff ID next to the barcode
  • Use the entire 14-digit number

Troubleshooting OCA Proxy

I can’t log in to OCA Proxy:

  • “Unrecognized Card” warning
  • “Ineligible” warning
    • OCA is for UCSC affiliates, contact us if you believe you are eligible to access OCA
  • “Blocked Country” warning
    • If you are trying to use OCA from China, Russia, Ukraine, or Iran email to enable access


I can’t log in to a specific journal or database

  • You shouldn’t have to log in to specific journals or databases when you are using OCA
    • Exception: SciFinder Scholar - see below for details
  • Make sure you are logged in to OCA and reload the page
  • Check Cruzcat to make sure the journal is in our collection
  • Ask a Librarian for help


I can’t log in to SciFinder Scholar

  • You need a username and password to access SciFinder Scholar Web in addition to using Campus VPN or OCA Proxy.

Register for a SciFinder Scholar username and password:

  1. Log in to Campus VPN or OCA Proxy
  2. Go to the SciFinder Registration page
  3. Use your email address to register for a SciFinder Scholar username and password


I can’t get past my firewall to access the OCA Proxy
