The study sampled Texas A&M distance learning graduate students to test what library resources they used, and why they used those particular resources. In this study the Internet was used the most, while libraries were the next most used resource for conducting class research. The study found that most students used these resources due to their quickness and ability to access from home. The study found that the principle of least effort was the primary behavior model of most distance learning students.[5] This means that modern libraries, especially academic libraries need to analyze their electronic databases in order to successfully cater to the needs of the changing realities of information science.
