Abstract
As online courses become more and more ubiquitous, the need for supporting services becomes more acute. To meet the needs of students in online courses for library services and instruction, means to deliver materials, reference services, and instruction electronically were developed or purchased by the University of North Texas in Denton, Texas. The needs of one particular class brought the problem into focus, so a team of librarians worked with the instructor to provide tools for the students to learn how to access information from a distance, and how to use it. This was accomplished by providing a class web page created to help the students locate specific journals in their fields, and a tutorial based on the Texas Information Literacy Tutorial, which was developed by the University of Texas at Austin. From this experience, a list of resources, procedures, and materials was developed to guide the library practitioner in providing library services for distance learners.
