Some Christian publishers are taking the expensive step of using plagiarism software during their editing process to guard against intentional and unintentional plagiarism, according to World Magazine. Emily Belz writes:
Most publishers think authorial self-preservation, strict contracts prohibiting plagiarism, and a good team of editors will result in a plagiarism-free book. But when plagiarism is unintentional—a missed citation or a miscopied note from a research assistant or just sloppiness—those checks can be insufficient.
I saw this kind of unintentional plagiarism or sloppiness while editing a set a workbooks a few years ago. Usually I was verifying a quotation to see if the attribution was correct, and some of them had incorrect or odd punctuation, so I tried to find an adequately sourced quotation in order to correct what my manuscript. A couple times I found the quotation and surrounded text were all quoted from another work and improperly attributed.
Professor Collin Garbarino gives World this explanation for this persistent problem. “We’ve got some pastors writing books on topics that they only superficially understand. If you haven’t mastered the subject matter, you’re going to have to rely on someone else for your ideas. If you’re under a deadline, you might cut corners.”
