You found an article in PubMed but it requires payment to access it. Now what?
You can search for it in the library to see if it is available through one of the databases that the library subscribes to!
In the search box on the Purdue Global Library's homepage, put the title of the article into the search box: Malignancy-associated pruritus
Change the drop down menu so that the word Title appears. Doing that means that only titles will be looked at when the search is performed.
Click on Search.
If the library does have access to it, it will be the first item in the results list. Sometimes it is down the list a little ways but usually it is the first item.
