The University of North Texas (UNT) Libraries conducted a study on the value of the UNT Digital Library, including its UNT Scholarly Works institutional repository, to investigate the value of the UNT Libraries' digital repositories as perceived by UNT faculty, staff, and graduate students. This evaluation of the impact of the UNT Libraries'interventions begins a longitudinal view of the overall impact of these digital repositories in order to inform decisions and provide baseline measurements against which future assessment results can be compared. Findings include that an increase in awareness of the UNT Libraries' digital repositories is statistically associated with a greater likelihood of multiple types of use and contributions back to digital repositories. Also, graduate students are, as a whole, more likely to be aware of and use the UNT Libraries' digital repositories than faculty or staff.
The University of North Texas (UNT) Libraries has developed a unique collection assessment tool, the Collection Map, to provide support for a new access-based collection development philosophy. UNT Librarians realized the limitations of traditional assessment methods to gauge the impact of emerging acquisitions models such as demand-driven acquisitions (DDA) and large interdisciplinary e-book collections. What was needed was a flexible, nimble assessment system to track access, holdings, and interlibrary loan (ILL) activity for each academic discipline. The Collection Map is a database that links items, and their associated data, to any one of several dozen overlapping subcollections via Library of Congress call numbers (LCCNs). The Collection Map's unique many-to-many relationship of subcollections to items and data enables librarians to demonstrate support for subject areas and to make more informed collecting decisions. This article describes the components and creation of the Collection Map, including manipulation of existing systems to extract data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
