How to create a reliable link?

to e-books or journal articles, for example in Nestor

Three things must be taken into account when constructing a hypertext link to an electronic journal article or to a part of an e-book:

1. Link via the proxy-server for home access

2. Use a permanent internet address

3. In Nestor, open link in a new window

1. Include the proxy for home access

When constructing a hypertext link to a certain journal, journal article or e-book, always link via the proxy-server. This ensures that students can have access to the publication from outside the RUG – from their home address for instance – as well as from inside the RUG. This can achieved by starting off the link with:
Paste the url of the publication behind the proxy.

How does it work ?
If a student is working from home or elsewhere outside the RUG and clicks on this kind of link, a log in screen will appear automatically, allowing the student to log in using his/her student account. Then the publication will appear on the screen. If a publication is accessed from within the RUG-network it is shown immediately, no log in is needed.   

For publications freely accessible on the internet, you can leave out the proxy section.  Note: you can only establish this when your’re working on a PC outside of the RUG/UMCG network, and when you’re not logged in on this network.

2. Use a permanent internet address

You also have to make sure the internet address used in the link is a permanent one. Usually this is a different link than the URL which appears in the address bar at the time the item is on your screen.


  • Use a DOI code
    Many publishers assign a so-called Digital Object Identifier (DOI) to each publication.
    An example of such a doi is: 10.1111/ddg.12424
    If you copy this code into your link, you can be sure that the link will stay operative, even if the content is moved to a different site. A link with a DOI code consists of three parts:
    1. First, mention the proxy server address:
    2. Behind that:
    3. And then the DOI code, for example: 10.1111/ddg.12424

    The link will look like this:
  • Or use a permanent URL
    Other publishers assign a permanent URL to an article. Such a URL can be used in a hypertext link. It may say 'persistent URL', 'permanent URL' or 'Permalink’. By clicking on this, the URL appears which you can use (and don’t forget to put the proxy-server URL ahead of it). The reference to a persistent URL is sometimes located in menu ‘export’ or ‘cite’, or indicated by an icon for exit, export etc.
Record link
Record link
  • Or re-use a link you have found on the library website or SmartCat
    The links to e-books, e-journals and databases can be found on the library's website, in the libguides. The links in SmartCat are always permanent and include the proxy. In SmartCat, click on the arrow and choose 'Record link'

Persistent links are not always available. Particularly not for publications which are freely accessible on the internet. In these cases, use the URL in the address bar of your browser.

3. In Nestor: open link in a new window

When the link is posted on Nestor, always choose the option ‘Open in new window’. Otherwise, Nestor may give an error message when the student tries to open the link.
