This paper is an analysis of Intranets and Extranets at selected state libraries in the United States. The paper does not review World Wide Web sites designed for use by the general public; rather, it focuses on Web sites designed and delivered by the state library to a targeted audience, typically state government employees, state library employees, or the library community. The author sent an electronic message to all state libraries, providing a definition of both an Intranet and an Extranet, and asked if any states managed or were part of an Intranet or Extranet whose URL could be shared. Intranets and/or Extranets of the state libraries in Alaska, Colorado, Ohio, Oregon, Rhode Island, and Utah were examined and analyzed in four basic areas: organizational placement of the Web site; content of the Web site (both Intranet and Extranet); a critique of the site design for ease of use and navigation; and observations and recommendations for those designing Intranets and Extranets. Two tables present comparisons of content by state for Intranets and Extranets. (MES)
