Find Full Texts: Proxy Bookmarklet

Guide on finding full-text using Find it! @NUS Libraries, ProxyBookmarklet and LibKey Nomad

Using Proxy Bookmarklet

The proxy bookmarklet automatically inserts the NUS Libraries proxy stem ( into the URL of an article/e-book. Once you have successfully installed the bookmarklet in your browser, simply click on it when you are on the publisher's page that requires you to pay or login to view full text. The system checks if the required title is within the Library's subscription. If yes, the page reloads and subsequently provides you with the full text options.

What if you get an error message or still cannot access full text using the proxy bookmarklet?

cautionThe proxy bookmarklet may not work in the following conditions:

  • NUS Libraries do not have a subscription to the title.
  • NUS Libraries have not yet configured the proxy to work with that page.

If for some reason the proxy bookmarklet does not yield any results, search for the source title in the Library catalogue (LINC). It is possible that the required title is available via another vendor site or in print copy (not online).
