This library study guide was designed for business marketing students at the University of Wisconsin, Stout. The guide, and its accompanying exercises, were developed as an alternative to providing library instruction to approximately 150 business marketing students each semester. The guide introduces students to basic business reference sources in five categories: (1) newspaper and magazine indexes; (2) statistical resources; (3) industry specific resources; (4) directories; and (5) financial resources. Descriptive abstracts of each resource are included. Several questions are provided for each resource with accompanying answer keys. Five versions of the questions and five answer keys are provided to accommodate large classes. (THC)
