This document discusses the past, present, and future of information services. In the past, reference services involved well-trained librarians and assistants providing friendly, personalized help to patrons. Today, services are offered both onsite and remotely through technologies like chat, text, and social media. Looking ahead, librarians anticipate providing more services outside of the library using mobile devices and collaborating directly with researchers through embedded roles. Adapting to new technologies while maintaining quality customer service will help ensure libraries remain relevant in the future.
