What is a proxy bookmarklet

unduhan-24The proxy bookmarklet automatically inserts the NUS Libraries proxy stem “libproxy1.nus.edu.sg” into the URL of an article link in your browser. Once you have  successfully installed the bookmarklet once, you can access full-texts of journal articles that are within the NUS Libraries’ subscription by clicking on the bookmarklet on any page that requires you to pay. This will attempt to access the resource via NUS Libraries’ sunscription.

Please note that this method does not work 100% reliably on all databases and sources (See exceptions). An article may also be available in multiple locations, aggregators.

Alternatively, if you are using Google Scholar or PubMed the following NEW method of accessing full text via NUS Subscriptions will avoid some of the problems listed above.

The proxy bookmarklet allows you to directly access full text of E-resources via the subscription of NUS.  The video below shows how to install and use proxy bookmarklet to access full text of a reference obtained from a Google Scholar  search. Please note that this will work for most but not all sites.

Why should you use the proxy bookmarklet?

Scenario 1:
You searched Google and found some relevant titles in the list of search results.  However, when you click on an article link, you are redirected  to a vendor or publisher’s site where you will be asked to pay for the full-text.

Scenario 2:
You receive direct links to online articles from a friend and after reading the abstract, you want to read the full-texts.  Similarly, when you click on the article links via email,blogs, twitter and you are directed to the publisher or vendor site where you are required to log in or pay to view full-texts.

Solution: Proxy Bookmarklet
Note that in the above scenarios, you are not coming directly from the NUS Libraries portal and hence the publisher/vendor site does not know that you have access via subscriptions from NUS.

You can of course, go back to our library portal and search the database or journal from there, but there’s a faster way to authenticate and access the article directly. This involves adding the proxy stem to the URL. One way of doing so is to use the proxy bookmarklet.

Easy to access the full text of journal tips

Google Scholar is a good resource to use for searching but the main drawback is that it is difficult to

a) check if you have access to the article displayed online via NUS Libraries subscriptions

b) get access even if the article is accessible via NUS Libraries subscriptions as the publisher is unaware you are from NUS, so when you click through Google Scholar into the article you will be asked to pay.

There are two main ways to help solve these two issues though they are not fool-proof as Google Scholar is a free tool.

Firstly, you can use the older proxy bookmarklet method, but this may not always work.

The second method, involves using the build-in Google Scholar’s Library Links  Programme which NUS Libraries is now registered with.

If you add NUS Libraries to your settings (see section below), Google Scholar will try to identify what articles you have access via our subscriptions and show a Find it! @NUS Libraries link.

Alternatively you can bookmark the following special google scholar link and search from there, which will do the same.

Here’s how you add this to your settings

1. At Google Scholar, click on Settings at the top right corner. (Note Google, often changes the position of this)

2. Click on Library Links on the left.

3. Search for nus and select National University of Singapore – Findit! @NUS Libraries

4. Click Save.

If you have logged-in using your Google account already, this setting will be tied to it, if not it will be tied to a cookie on your PC that may be cleared depending on your settings. See this for details.

Text of journal from PubMed to access tips

PubMed is a free citation database that contain items from various sources including Medline. While PubMed might link to full-text, some of which is free in PMC or other open access or free titles, most items require a subscription and not all such items can be accessed via NUS Libraries subscription.

So how does one identify what items can be accessed via NUS Libraries subscriptions?

This is a normal URL that you can bookmark on desktops or iPads (but see the following note). You can also access it via the Library portal, catalogue etc.

Alternatively, if you have your own My NCBI account you can also change your settings to support this.

For more details watch the following video from NLM

Once this is done, you can do the following.

If you want to see results that only can be accessed via NUS Libraries’ holding, after running a search, click on the filter on the right, National University of Singapore Libraries.

This will restrict results to just items PubMed thinks we have access to via NUS Libraries. The number in parentheses indicates the number of results.

Please note that while this will include some free and open access articles that we have included in our holdings (you can restrict to this by clicking on Free Full text available filter on the left), this won’t usually overlap 100% with PubMed’s Free full text filter (all articles known to be free via PMC or publisher by PubMed) alone as we don’t include all free journals in our holdings.

It may also miss some of the most recent articles just posted that are [PubMed – in process] , or [PubMed – as supplied by publisher]

Alternatively, click on an article you are interested in and look for a button that says “Find it! @NUSLibraries”

The same button can be seen at the bottom of each record, if the Display setting is set to Format — Abstract.

In either case, clicking on the button will usually bring you directly to full-text, though occasionally it may drop you into the 360link results page (instructions on what to do), or in the worse case scenario, the page in the bottom frame fails to load in which case you should click on “Get additional resources”.

Sometimes you will see other buttons, if it is free from publisher as below. Typically such buttons will have the word “Free” or “Open Access”.
