This document discusses information services and reference interviews in libraries. It defines information services as any service intended to provide information for users or assist them in finding information. Libraries traditionally provide reference services like answering questions and helping patrons find information. The goal of reference work is meeting users' information needs through finding what they need and using library resources to provide it. An important part is the reference interview, where the librarian determines the real question by asking questions and listening to understand the user's full information need. The reference process involves encouraging contact, understanding the need, finding information to meet it, and ensuring the need was met. Effective questioning techniques and getting key details from users are important parts of the reference interview.
