Creating stable links to library e-resources

If you currently provide your own links to library e-journals, e-books etc, they probably contain .ezproxy.liv.ac.uk int he URL. These links should continue to work. Nevertheless it is a good idea to update them to new-style links next time you come to review your links.

To create new-style links, remove .ezproxy.liv.ac.uk from the URL and instead add http://ezproxy.liv.ac.uk/login?url= to the start of the URL.

For example, instead of:

http://inpractice.bmj.com.ezproxy.liv.ac.uk/

use:

http://ezproxy.liv.ac.uk/login?url=http://inpractice.bmj.com/

Note that the result of following such a URL is that you will arrive at either:

http://inpractice.bmj.com.libproxy1.liv.ac.uk/

or

http://inpractice.bmj.com.libproxy2.liv.ac.uk/

However, you should never use URLs that contain libproxy1 or libproxy2 in bookmarked links or links embedded in VITAL etc. To link to sites via EZproxy always use URLs that begin http://ezproxy.liv.ac.uk/login?url= .

It is probably easiest to locate a link to the resourve you want in the library catalogue and then right-click our 'View this... online' link, Copy the shortcut and paste it into VITAL or wherever you are placing your links.

To create deep links, for example to a journal article rather than to a whole journal, there is a tool in VITAL: in Sessions/Resources, choose Add Interactive Tool and find it @ liverpool Journals.

To build find it @ liverpool links outside VITAL, enter the article's details into our 'Go to an Article - journal, vol, page, year known' form at http://www.liv.ac.uk/library/e-library/e-journals.html and click the FIND IT button. That will result in a URL like:

http://sfxhosted.exlibrisgroup.com.libproxy2.liv.ac.uk/lpu?title=Geografiska+Annaler+Series+B+Human+Geography&volume=92&issue=1&spage=1&date=2010&issn=&eissn=

To turn that into the correct form replace:

http://sfxhosted.exlibrisgroup.com.libproxy2.liv.ac.uk/lpu (or libproxy1)

with

http://ezproxy.liv.ac.uk/login?url=http://openurl.ac.uk

to give for example:

http://ezproxy.liv.ac.uk/login?url=http://openurl.ac.uk?title=Geografiska+Annaler+Series+B+Human+Geography&volume=92&issue=1&spage=1&date=2010&issn=&eissn=

An alternative approach for journal articles is to link via the article's DOI, as long as were have access from the publisher's site where the DOI links to, and not at EBSCO or ProQuest for example.

To link via the DOI, just add the DOI to the end of:

http://ezproxy.liv.ac.uk/login?url=http://dx.doi.org/

for example:

http://ezproxy.liv.ac.uk/login?url=http://dx.doi.org/10.1111/j.1461-0248.2012.01770.x

For some resources, notably some e-book platforms, we do not link via EZproxy at all:

For ebrary, do not include EZproxy in the link. For example, just use a link like http://site.ebrary.com/lib/liverpool/Doc?id=10147034 like we do in the library catalogue, see http://library.liv.ac.uk/record=b2135120~S6. Ebrary will detect off-campus users and direct them through their own EZproxy single sign-on mechanism.

For some other sites, notably Dawsonera and Myilibrary, we use Shibboleth (usually known as Institutional Login) which usually uses horrible long URLs like:
https://www.dawsonera.com/guard/protected/dawson.jsp?name=urn:mace:eduserv.org.uk:athens:provider:liv.ac.uk&dest=http://www.dawsonera.com/depp/reader/protected/external/AbstractView/S9781846314162 (see e.g. http://library.liv.ac.uk/record=b2492636~S6).

Please contact your liaison librarian if you have problems building stable links to our e-resources.
