Visual Maps of the World Wide Web

Summary

The difficulties of finding intellectual content in the multidimensional environment of the Internet pose new problems for the LIS professionals and for the users they seek to serve. Many Internet users report the “lost in cyberspace” phenomenon and print publishing has flourished surrounding users' need to find good intellectual content on the World Wide Web. This paper examines the cognitive aspects of arrangement and organization on the Internet and then examines some of the techniques being used to create maps of the intellectual content found there. Through many centuries, maps have been a helpful cognitive aid in providing a practical congruence between a large, three dimensional landscape and a portable, intuitive, two dimensional reference source. Some of the same features of maps are being used to provide some cognitive sense of the contents of special topical areas on the Internet and particularly the World Wide Web.

Biology Sites on the World Wide Web

Abstract

Access to biological information on the World Wide Web continues to grow at a rapid pace. Many resources that previously required a trip to the library are now accessible from the desktop PC. Three major categories of biology Web sites are explored: those with citation information, those functioning as clearinghouses or directories to other Web sites, and those that present biological information in innovative ways. The suggested Web sites are some of the best and may serve as models for future Web development. Many useful citation Web sites are fee-based and are likely to continue as such for the near future; MEDLINE and AGRICOLA are important exceptions. Many significant clearinghouse and information Web sites are not fee-based and allow innovative ways of finding and sharing information. The state of research information on the WWW is not developed enough for the researcher to forego using paper sources.
