The answer is c. During the 2003-04 academic year, 401,403 items were borrowed from the UNT library system. This includes regular circulating times, items on reserve and items specially checked out.
And that's no surprise. The UNT library system, with 5.5 million cataloged holdings, has been designated a major research library by the U.S. Department of Education. In addition to on-the-shelf items, electronic resources are available on the library system's web site at http://www.library.unt.edu/.
For instance, the web site is home to the CyberCemetery, a federal depository of documents, publications and web sites of defunct U.S. government agencies and commissions. The CyberCemetery's most recent addition is data from the U.S. Commission on National Security/21st Century (a.k.a. the Hart-Rudman Commission).
