"... Perhaps because of the new law’s complexity, a full response by the  profession has been evolutionary in nature. By April 2002, the ALA Office of  Intellectual Freedom (OIF) had conducted extensive evaluation and assessment of  the implications of the USA PATRIOT Act and published The USA Patriot Act in  the Library: Analysis of the USA Patriot Act Related to Libraries (American  Library Association Office for Intellectual Freedom [OIF], 2002). This document  provided a straightforward explanation of the relevant sections of the Act  without making any recommendations as to how librarians should respond if faced  with an investigation. Two months later, in June, the ALA Council approved  Privacy: An Interpretation of the Library Bill of Rights (ALA, 2002),  stating,
  "In a library (physical or virtual), the right to privacy is the    right to open inquiry without having the subject of one’s interest examined or    scrutinized by others. Confidentiality exists when a library is in possession    of personally identifiable information about users and keeps that information    private on their behalf."
 By January of 2003, the ALA codified a three–fold response to the Act in its  Resolution on the USA Patriot Act and Related Measures That Infringe on the  Rights of Library Users. First, the resolution urged education about how to  comply with the Act and also about the inherent dangers to intellectual freedom.  It further urged that libraries "adopt and implement patron privacy and record  retention policies" [41] to  collect only information that is necessary for the library’s work. Second, the  resolution bound the ALA to work with other like–minded organizations "to  protect the rights of inquiry and free expression" [42]. Third,  it commited the ALA (2003a) "to obtain and publicize information about the  surveillance of libraries and library users by law enforcement agencies."
 In fulfillment of these resolutions, the ALA has initiated a number of  actions. For library workers and managers, the ALA created a support system  focused on challenges that might arise during day–to–day library operations. On  its Web site, ALA provides extensive educational materials, both for use in  familiarizing staff members and communities about the issues, as well as in  developing local policies for record retention and search warrant response,  including What to Do If Served with a Search Warrant under USA Patriot  Act (OIF, 2004). In addition, the OIF offers legal assistance through the  Freedom to Read Foundation to any library served with a warrant and does not  have an attorney.
 In terms of establishing coalitions, the ALA collaborated with the American  Booksellers Association and the PEN American Center to form the Campaign for  Reader Privacy, initiating a nationwide campaign to gather signatures in support  of legislation to amend Section 215 ("Million Signatures Sought," 2004). Lastly,  in an effort to publicize the surveillance that has occurred, the ALA submitted  a FOIA request for the number and content of subpoenas issued under Section 215  [43].  When the Justice Department failed to respond, the ALA participated in another  collaborative effort — a joint lawsuit with the American Booksellers Foundation  for Free Expression, and American Civil Liberties Union, and the Electronic  Privacy Information Center (Sommer, 2002, Request Denied section). On 20 May  2003, the House Judiciary Committee obtained information from the Justice  Department that "FBI agents have contacted about 50 libraries as part of  investigations" (Oder, 2003b).
 ALA President Carla Hayden publicly challenged the Justice Department to make  available the records sought in the FOIA request. Attorney General John Ashcroft  mocked the request, adding offensive remarks deriding the significance of the  ALA’s concerns (Goldberg and Foote, 2003). Hayden’s reply was swift and clear,  "We are deeply concerned that the Attorney General should be openly contemptuous  of those who seek to defend our Constitution" (ALA, 2003a). On September 18,  Ashcroft agreed to declassify the report on library visits, but he claimed that  the FBI had not used Section 215 powers in any of the contacts. Critics noted  that this was an indication that the Justice Department could restore pre–USA  PATRIOT Act standards without hampering intelligence efforts (Lichtblau, 2003;  Oder, 2003a). ..."
