Frequently Asked Questions

What is the Off-Campus Access service and why do I need it?
Contracts with the library's database and journal vendors require us to restrict access to faculty, staff, and currently enrolled students of the University of California, Santa Cruz. On-campus connections to subscription resources are automatic. When users are off campus, they need to prove to the database publishers that they are authorized users of the resource. By using Off-Campus Access, your browser becomes part of the UCSC network, regardless of your location. When you attempt to access a library resource, you will be prompted to log in with your library card number (without spaces or dashes). This information is matched against the library patron database and those in authorized patron groups will be connected. You will then be automatically admitted into additional restricted resources for the duration of your online session.

Which browsers are supported?
OCA is browser-independent, i.e., any browser should work with the service. A current browser should be more reliable.

What do I have to do to use Off-Campus Access?
OCA should require no configuration on the user's part. You only need an activated UCSC Library card. (If you've ever checked out a book or video, you're activated.) When you click on a link to an online library resource, OCA checks whether your computer is on campus or off.
* If you are on campus, you will bypass OCA and be sent directly to the resource.
* If you are off campus, you will be required to login with your UCSC Library barcode number, then be sent to the resource.

Where is off-campus?
Off-campus refers to locations that are not physically on the UCSC campus or in UCSC buildings. Dorms and apartments on Resnet are considered on campus. Classrooms and offices (including those at UBP and ITS Delaware) and are also considered on campus. Homes and businesses in the Santa Cruz area and around the world are "off campus."

How do I sign into Off-Campus Access?
If you are not using an on-campus computer, then you will be prompted to sign in to OCA the first time you try to access a restricted resource. If you prefer, you can go ahead and login now. Once logged in, you will remain logged in until you close your browser.

When I follow a link to log into OCA directly, it doesn't give me the sign-in page.
If you are already signed in to OCA, it won't prompt you again. Look at the URL shown in the Location or Address bar at the top of your browser. Does it include the words "oca.ucsc.edu"? If so, then you are already signed in and won't be prompted again.

How do I know if I'm already signed into OCA?
Look at the URL shown in the Location or Address bar at the top of your browser. Does it include the "oca.ucsc.edu"? If so, then you are already signed in.

Can I use OCA to access SciFinder Scholar from off-campus?
Right now there isn't a way to search SciFinder Scholar or Crossfire through the OCA server. It doesn't work with the old SlugLink proxy service either. These proxy servers are not able to provide off-campus access to any site that uses a separate client for searching (other than a browser). The developer for EZ Proxy, the software behind OCA, is working on a solution for SciFinder Scholar in particular. There are many institutions, including us, that are anxious to see a solution. A beta test should be out in spring to summer 2007. We will keep the UCSC chemistry community posted.

After entering my library barcode, I get an error that says "UNRECOGNIZED CARD."
Try it again, to rule out typos. Make sure you are entering all 14 digits of your library card number. If you are still having problems, contact the McHenry Library or the Science & Engineering Library Circulation Desk at (831) 459-5185 or (831) 459-5300 to verify that your barcode number is in the system. If you prefer, feel free to email them at circulation@library.ucsc.edu.

After entering my library barcode, I get an error that says "INELIGIBLE."
Contracts with the library's database and journal vendors require us to restrict access to faculty, staff, and currently enrolled students of the University of California, Santa Cruz. If you think there is an error and you should have access, please contact the McHenry Library or the Science & Engineering Library
Circulation Desk at (831) 459-5185 or (831) 459-5300. You can also send an email to circulation@library.ucsc.edu.

While trying to access a database or journal, I get a "404 Page Not Found" or "File Not Found" message.
This usually means there is a problem on the vendor's end. Please report the problem to Ask a Librarian or call the McHenry Library or the Science & Engineering Library Reference Desk at (831) 459-2711 or (831) 459-2886. Include the title and URL of the resource if you report the problem using the Web form.

While trying to access a database or e-journal, I get a CONFIGURATION ERROR from the OCA server.
The site has not been properly configured by the library's Off-Campus Access administrator. Please report the problem to the library at oca@library.ucsc.edu. Include the name of the resource and the URL in the e-mail. We'll work to resolve it as quickly as possible. In the meantime, you may want to contact the library Reference staff using the Ask a Librarian form or call the McHenry Library or the Science & Engineering Library Reference Desk at (831) 459-2711 or (831) 459-2886. We often have subscriptions to one journal from multiple sources and the library staff may be able to offer some alternatives.

While trying to access a database or e-journal, I'm getting prompted for a login and password from the publisher's site.
The problem is probably one of three things:
* You've found an online journal (or issue of a journal) to which the UCSC Library does NOT subscribe. It is often difficult to discern which journal issues are in the UCSC Library's holdings once you're on the publisher's site.
* The Library may need to adjust our configuration of Off-Campus Access for the particular database or journal site.
* You've gone straight to the journal's Web site from off-campus without going through the UCSC Library's Web site. If you think this is the case, try using the OCA Bookmarklet. This will reload the journal page through the OCA server. If that doesn't work:

Contact the library Reference Desk to confirm the root of the problem. The librarians may be able to suggest an alternative e-journal site and they'll follow up with appropriate staff if we need to adjust our OCA configuration. Call the McHenry Library Reference Desk at (831) 459-2711 or the Science & Engineering Library Reference Desk at (831) 459-2886, or submit the problematic site to Ask a Librarian.

I get past the OCA login page, but when I click on links, nothing seems to happen.
More than likely, this is due to pop-up blockers set up on the computer you are using. See the answer above.

Why don't certain features or links in the database seem to function when I'm using OCA?
If certain links or other aspects of the site aren't functioning, there are a few primary possibilities:
* The database vendor or e-journal publisher is having a technical problem.
* We may not have a subscription to the particular issue or volume of the journal you're trying to access. It is often difficult to discern which journal issues are in the UCSC Library's holdings once you're on the publisher's site.
* The Library may need to adjust our configuration of Off-Campus Access for the particular database or journal site.

Contact the library Reference Desk to confirm the root of the problem. The librarians may be able to suggest an alternative e-journal site and they'll follow up with appropriate staff for a long-term solution. Call the McHenry Library Reference Desk at (831) 459-2711 or the Science & Engineering Library Reference Desk at (831) 459-2886, or submit the problematic site to Ask a librarian.

Whom do I contact if I am still having problems searching?
Call the McHenry Library Reference Desk at (831) 459-2711 or the Science & Engineering Library Reference Desk at (831) 459-2886, or use the Ask a librarian site to submit an online question.

Should I stop using SlugLink?
Yes. We recommend that you remove it because it is no longer necessary, and continuing to have the browser configured for the proxy server can slow down your access. Here are instructions for removing it.

What happened to the "Set up my computer" link for SlugLink information?
We don't need it anymore. Off-Campus Access, the new service from the Library, does not require users to configure their browsers. It's also faster.

I have the old libproxy.ucsc.edu (SlugLink) proxy server configured on my browser. Is that a problem?
We recommend that you remove it because it is no longer necessary, and continuing to have the browser contact the proxy server can slow down your access. Here are instructions for removing it.

I want an easier way to connect to databases and journals without going through the library Website.
Use the UCSC OCA Bookmarklet. Faculty often find themselves on restricted access pages without going through the library website. You may received links to ejournal articles through email alerts, or through RSS feeds, or links in online papers. Instead of going to the library's homepage and logging in, then searching for the journal just to return to the page in question, try this bookmarklet and save all of those steps. By clicking on this bookmarklet, you will be redirected through the OCA server for the page you are currently viewing. In some cases you may need to use the browser's "Back" button to return to the resource URL, not the vendor's login/error page. To download the bookmarklet, right-click on the UCSC OCA Bookmarklet link above and choose "Bookmark this link..." or "Add to Favorites". Or, go to the bookmarklet page for more instructions. When you are on a Web page you'd like to run through the OCA server, simply choose that bookmark from your Favorites or Bookmarks menu. This even works with Google Scholar search results page.

DOI Lookup
(IE DOI Lookup: Internet Explorer version)
Digital Object Identifiers are unique IDs for online articles, conference papers, e-books and other online information. To download the bookmarklet, right-click on the DOI Lookup link above and choose "Bookmark this link..." or "Add to Favorites". To use it, highlight a DOI on a web page, then click the DOI Lookup bookmarket to locate the "digital object" online.

Try it with this DOI: 10.1016/S0388-0001(01)00045-6

How do I maintain my own Web page links or bookmarks of library e-resources?
You'll need to change the links to your licensed resources to invoke the OCA server. Do this by prefixing your URL with the OCA server URL, http://oca.ucsc.edu/login?url=. So, if you have a link in your page to:
http://a.library.licensed.product
You must change it to:
http://oca.ucsc.edu/login?url=http://a.library.licensed.product
The link to the restricted resource must be absolute (starting http://); it cannot be a relative URL.
Alternatively, you can download the UCSC LibX Firefox extension. This extension allows you to right-click on any link and load the page through the OCA server.

I use Google Scholar. How to I make UC-eLinks show on the results page, like it works on-campus?
You'll need to run your Google Scholar search through the OCA server. Use the following link to connect to Google Scholar:
http://oca.ucsc.edu/login?url=http://scholar.google.com. You can bookmark that site or search for it in the library electronic resources database.

My computer is behind a corporate firewall. Can I still use OCA?
If you are behind a firewall and require access to UCSC Library resources, your network administrator will need to create a firewall rule that specifies the UCSC Library's proxy server as a Trusted site. The address to use is: oca.ucsc.edu. Network administrators should be able to allow access to our entire proxy server via this address. Network administrators requiring further information can contact the OCA administrators at oca@library.ucsc.edu.
