Those Pesky Interlibrary Loans

A senior at UMass Dartmouth was visited by federal agents two months ago, after he requested a copy of Mao Tse-Tung's tome on Communism called "The Little Red Book."
Two history professors at UMass Dartmouth, Brian Glyn Williams and Robert Pontbriand, said the student told them he requested the book through the UMass Dartmouth library's interlibrary loan program.

The student, who was completing a research paper on Communism for Professor Pontbriand's class on fascism and totalitarianism, filled out a form for the request, leaving his name, address, phone number and Social Security number. He was later visited at his parents' home in New Bedford by two agents of the Department of Homeland Security, the professors said.
... The eavesdropping was apparently done without warrants.
