I was very pleased that NJIT early on bought into "turnitin.com" which is an amazing system. Since i have a lot of project type assignments with write ups, before that i had to guess at what might be cases of plagiarism and put in google searches. If you have never used it, it accumulates files of everything on the web and any papers by students for future use. It was amazing to find a paper by a student using un-noted quotes from a paper by a student at some foreign university. It keeps a database of all your student papers and if some other professor gets a match, they ask your permission to give them access to the whole paper. At the graduate level and senior courses i finally gave my students access to put in their papers and modify them using the results till they were satisfied that the only quotes were clearly referenced. I also got in the habit of putting in papers i was asked to review from professional conferences and journals and some of those were rather surprising on the lack of clear attribution for what they were using. I would even put in my own drafts as sometimes you are unaware something you used recently was really something you read many years ago. I think journals, conferences should sponsor access for authors and reviewers. Since retiring i miss the regular use of it. It was also useful in checking for missing references. It even shows quotes of partial sentences where the student was trying to reword the quote without referencing it. Finding 20 or so papers used to make the paper was not unusual. -- Distinguished Professor Emeritus Information Systems, NJIT homepage: http://is.njit.edu/turoff
