Moving from simplistic, open web search strategies sufficient for high school level work to independently navigating the complex system of information sources available on college campuses is a developmental milestone for undergraduate students. One of the aims of library instruction is to play a critical role in this transition to college-level research, which necessitates the use of specialized databases and other information sources. Instruction librarians raise awareness of library e-resources and provide in-depth guidance in selecting and effectively using online sources. Santa Clara University librarians were interested in investigating the immediate impact of instruction on the use of the library’s e-resources. Do students regularly use library resources after instruction or do they revert to open web sources when searching independently? To study this question, Santa Clara University librarians examined LibGuides statistics, usage data, and instruction data to determine how frequently students access library databases post-instruction. The investigators examined LibGuides associated with course instruction from a selection of classes and explored the potential impact of instructional techniques, timing of instruction, and assignment integration on sustained use of electronic resources. The investigators also examined use of resources by level of course to explore whether independent use of library resources increased as students progress through their college years. This poster will share methodologies for assessing use of library e-resources after instruction using LibGuides statistics combined with usage and instruction data. The poster will also explore opportunities for implementing this method to assess instruction, access, and use of e-resources on college campuses. Speakers
