I had not intended to enter the fray, but Cathy Wolfson's comments reminded of the time when in 1992, I believe, I was asked to get UIs for every citation in Cancer Medicine. There must have been about 2000 citations and a larger percentage than I would care to think had errors. I was glad I could help clarify them. Over the years I have helped people on occasion because they had a printed bibliography with incorrect information. If necessary I have contacted NLM so they could fix things on their end, too.
