The broker does not simply provide a bibliography, but must often find an answer. Analysis, evaluation and writing skills are critical. An online searcher in an academic library may simply hand over the entire transcript of a search to a patron. A broker cannot do this. The person who acquires a Dialog password has only taken the first step building a career as an information broker.
Research also involves print materials and human experts.
Trade associations and government agencies are important resources. The broker must be able to locate likely people and get the needed information from them directly. One aspect of the research process often under-emphasized in traditional reference courses is the reference interview by telephone. Brokers meet few of their clients in person. Role playing of reference interviews, including especially those interviews done over the phone, are important part of the training.
