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?
The easiest way is to always access PubMed via this special URL link - http://libproxy1.nus.edu.sg/login?url=http://www.ncbi.nlm.nih.gov/pubmed?myncbishare=nuslib&holding=isgnuslib_fft .
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.
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".
Similarly you may see free articles deposited in PMC
In either case, you can get access to the text by clicking on the free button (preferable) or by clicking on our "Find it!@NUSLibraries"
You may also see other buttons that belong to publishers.
You should click on them as a last resort, if there are no free buttons or Find it! @NUSLibraries buttons. These buttons will bring you to the publisher sites, but there is no guarantee if the library has access to it on those sites.
If none of these methods work, you will have to check using the official method to check for availability online or in print and if not, it is not available.
