LibGuides are an essential resource in academic libraries. Although librarians use LibGuides primarily as instructional tools there is little discussion about the application of pedagogical and learner-centered design principles to the design of LibGuides. Current research focuses almost exclusively on issues of usability, resulting in best practices that are user-centered but not necessarily learner-centered. This paper fills the gap in the literature by integrating the findings from user studies with instructional design principles to propose best practices for LibGuides that are both user- and learner-centered. The ADDIE model of instructional design is used as a procedural framework for implementing these best practices.
