This brief describes how the Internet serves as a professional development tool, enabling individuals to access information on employment opportunities, workplace trends, prospective employers, and job search strategies. Websites may offer only one service or include a variety of features. Some services are available at no cost, others are fee based. The Internet offers thousands of job search sites, company websites, research sites, career development aids, and online networking resources. Developing an online version of the resume is essential today. Many job sites will post resumes, in most instances, as a free service. Assistance in preparing resumes is available at websites. Although no single website includes everything needed for the job search, the "big board" job banks give beginners a head start on locating the information they need. Most search engines have direct links to a variety of career- or job-related websites. (Contains annotated listings of 33 websites, grouped under these categories: the big board, federal/military, government websites, job search aids, professional/special, state and local, international, and company information. An annotated list of nine print resources is also provided.) (YLB)
