I've just been volunteered by my university to look into the cost-
effectiveness of subscribing to a plagiarism detection service, such 
as turnitin.com.

Naturally, I turn to you people for advice.

I just browsed their website. It seems to me rather complicated to 
make use of, although I suppose it gets easier once you understand 
how it works. But I would think this would limit the number of 
instructors who would be sufficiently motivated to make use of it in 
their courses.

They offer three options for subscribing: individual, department, or 
university-wide. However, they were rather coy on pricing, and you 
have to submit a request to get this information (which I haven't yet 
done). 

It seems to me that what they claim as their primary function--
detecting passages plagiarized from the Internet--can be easily 
duplicated without all the associated bother and expense just by 
typing a few suspected passages in quotes into Google. This works 
great, actually.

So the question is: do they offer anything more? They also maintain a 
database of papers submitted to them for analysis. However, my guess 
is that this would be valuable only if recyling of papers (handed on 
from one student to another)  are a concern, and would be effective 
only after a university had subscribed and submitted many papers to 
their database.

One benefit I thought they might have would be the ability to look 
within the databases of papers-for-sale sites, which Google wouldn't 
be able to access. In other words, I thought that perhaps they could 
detect purchased papers as well as those freely available on the 
Internet. But I don't see that they make this claim so it's probably 
not true.

Bottom line: I'd like to hear (publicly, preferably) opinions on 
this, particularly from people who have used turnitin.com or a 
similar service, particularly at a small university such as ours.  Is 
it better than googling? Is it worth the hassle to use it? Is it 
worth the price? 

Please tell.

Stephen
