Section 215 is often referred to as the Patriot Act’s “library records” provision because it allows the FBI to order a library or any other source to produce, without a warrant showing probable cause (as required under the Fourth Amendment), all “tangible things” belonging to its target of interest including “books, records, papers, documents, and other items.” That includes books borrowed and websites visited by the target while at the library. Niceties demanded by the Fourth Amendment are ignored in Section 215 as long as the FBI “specifies” that its order is “for an authorized investigation … to protect against international terrorism or clandestine intelligence activities.”
