Libraries Say Yes, Officials Do Quiz Them About Users

By ERIC LICHTBLAU

WASHINGTON, June 19 - Law enforcement officials have made at least 200 formal and informal inquiries to libraries for information on reading material and other internal matters since October 2001, according to a new study that adds grist to the growing debate in Congress over the government's counterterrorism powers.

In some cases, agents used subpoenas or other formal demands to obtain information like lists of users checking out a book on Osama bin Laden. Other requests were informal - and were sometimes turned down by librarians who chafed at the notion of turning over such material, said the American Library Association, which commissioned the study.
