Q. Why are some publications restricted to view (I am unable to download a copy of a paper)?
Some publishers don’t allow publications to be available in repository until some time after the publication date. In cases like these the publication’s view is restricted. If you come across a publication that you’d like to read but the view is restricted, you can click ‘Request a copy’ button and the publication’s team will forward a copy on, once it has been approved by the author.
