I've never had to grade papers for a class of undergraduates at a large university, but, from the impression I get from my instructor this semester, it's easier than ever to plagiarize a written assignment. For this reason, I was required to submit my first paper of the semester to a web-based organism called Turnitin.com, which is supposed to check your documents to make sure they aren't plagiarized in parts or as a whole. How it works is beyond my comprehension of the internet, but, from what I can gather, it searches the web for instances of phrases and similar writing that the writer may have used without giving proper credit. Oddly enough, one of the FAQs on the board has a question related to using one's own previous writing, and, it states that if you don't credit yourself, you're are, in fact, plagiarizing. Plagiarizing one's self? I don't know how you'd do it, but I'd love to see someone sue themselves for plagiarism.
