Library Proxy Server
You do not need the proxy server if you connect to the Internet through the UC Berkeley network in a campus building, residence hall, or via AirBears2.
If you connect to the Internet through CalVisitor, you will not be able to access licensed library resources, or use the Library Proxy Server to access licensed library resources.
Use the Library Proxy Server to remotely access UCB only article databases, electronic journals, etc. You must abide by the Library's conditions of use and licensing restrictions for electronic resources.

- Your web browser must be set to accept all cookies. If you'd prefer not to do that, consider using the Virtual Private Network (VPN) system rather than the proxy server.
- Use the Browser Configuration Check tool to find out if your browser is configured correctly.
- Browsers configured to use the proxy will give an error message such as Proxy Server Refused Connection when you try to access a resource URL that starts with https. If you encounter this error, please try accessing a different resource whose URL does NOT begin with "https" (such as the Oxford English Dictionary). You will be asked to log into the proxy. After you've logged in, please access the resource with the "https" URL again. Subsequent access to "https" resources within the same browser session should not trigger this error.
Alternative: use the Virtual Private Network (VPN).
