I can't comment on university level, but at school level this is a very common problem.
From very early on children are encourages to use the internet as a resource. this very often invols them cutting and pasting large amounts of information without even trying to put the information in heir own words.
'Use the internet to research THe Gunpowder plot' becomes 'Find the gumpowder plot on Wikipaedia and cut and paste it'
In part the teachers are at fault for not jumping on this hard enough. The children really think that they have done the 'work', which would be true if they were being tested on their ability to find stuff and cut and paste!
In part ir is understandable, because the kids know that the information they get on the internet looks good! and they want their work to look good.
We are getting round this bu setting up 'webquest' type activities, worksheets that make sure that the children find and read the information, before they give hand written answers on the sheet, quoting the website address.
This is an aspect of education that needs al lot of attention IMHO! We are simply not preparing the children to use the internet effectivly, and critically
