This directory lists information brokers, freelance librarians, independent information specialists, public and institutional libraries that offer information services, and information service companies in 29 states, the District of Columbia, and three Canadian provinces. Arranged alphabetically by state and then by broker/company name, the listings provide the address, telephone number, key individuals (if company/institution), hours of business, rates, services, areas of specializations, and--in some cases--further descriptions of specialties and past projects. A combined subject-person index is included. (JD)
