I had a young PhD working for me once in a research lab. She had to write a literature review on the subject of salt crystallisation. She beavered away for a couple of weeks and produced a document that comprised large verbatim quotes from various papers, stitched together with ill-formed sentences that were like a crude glue. This was pre-internet, so no cut and pastes were possible. The result, however, was very similar to a string of cut and pastes. It was an embarassment to have to present it to the client. I had to spend a whole weekend reading through it and writing an extended executive summary to put at the front of it so that the client had something useful and we didn't appear like incompetent idiots.
