UPDATE: Also, via LISNews, a new article from South Coast Today, which includes skeptical quotes from government agencies. It also mentions that the library which processed the request was UMass-Amherst, and refused to say whether they had received a government request for their records due to secrecy provisions under the Patriot Act.
UPDATE: Heretical Librarian gives a rundown of holes in the reported version of the student's story. My own opinion hasn't changed much. I still think that either the student is lying, or that there's more to this than we know. It can't just be the book.
UPDATE: Inside Higher Ed now has an article on this topic. It's new information is that the student's travels were to South America, and that he went to an FBI office to defend himself. I think the muddled picture of the first article could be explained if the professor, who was actually asked about the eavesdropping story, got some details muddled about these events of earlier this semester, not realizing they would become the centerpiece of the story.
