We had a guy e-mail about an article - ok. Standard thing - the article had been cited a bunch of times on Google scholar as:
“It’s us against them: The group dynamics of political terrorism”. Terrorism 1987, volume 10, issue 1, pages 23-35.
We located the journal (it's merged with another) on Informaworld, but the article in that journal at that page is by the same author but is named: “Rewarding Fire with Fire – Effects of Retaliation on Terrorist Group Dynamics”
Another librarian offered that to the customer, but he wanted the one that was cited. The librarian searched, and searched, and searched... Finally, she decided to e-mail the author. The author's research assistant also thought it was weird, but agreed to look when she went to the author's other office.
So here's the deal, the title "It's us" was on a sticker covering the original "Rewarding Fire". The copies that were located were the original reprints from the journal. Somehow, when the article got scanned, the uncorrected title was added to the record. Yup.
