The easiest way is to click on the link in Pure to the pdf of the article. It will send you to the publisher’s website.

If there is no pdf or link, there are several other options. Copy the title of the article and search for it on/in:
- Publisher’s website, for example PlOS ONE
- CrossRef Metadata search:
- Bibliographic databases such as:
- Web of Science
-
- Google Scholar
- Scopus (only when you have a subscription)
- Web of Science
There are also other databases based on discipline, where you search for a DOI.
It is always good idea to check the DOI here: http://www.doi.org/
