On The Fear Of Accidental Plagiarism

Over at NT Blog, Mark Goodacre shares a few abnormally interesting thoughts on accidental plagiarism.
I’m working on an essay that involves both a considerable amount of background knowledge and much new material. The new stuff is on a subject in which I have little or no training. For this reason, as I read I’m never sure what will be important later and what will not. But even unnoted things occasionally stick and I sometimes lose track of sources. Every time I write a sentence about this new material, I worry that I may be relying a little too heavily on something I read but did not note at the time.
