MSA Murchison Dataset
(2025-07-09) Farquhar, James; Bouyon, Amaury
1. Description of methods used for collection/generation of data: The data were obtained using a ThermoFisher MAT 253 dual inlet mass spectrometer and are the output data from the mass spectrometry software. The software calculates isotopic data and reports them in the delta notation from ion beam intensity ratios using standard sample standard bracketing. The extracts were prepared using protocols described in Labidi et al 2017 (https://doi.org/10.1016/j.gca.2016.09.036). 2. Methods for processing the data: The raw data are processed in the file by first renormalizing the data to sample gas from the international standard reference material IAEA S-1 and then converting this normalization to the Canyon Diablo Troilite Reference scale of Dottin et al 2023 (https://doi.org/10.1029/2022JE007597) using values reported in that paper. 3. Instrument- or software-specific information needed to interpret the data: MS Excel, or other software able to read .xlsx format 4. Standards and calibration information, if appropriate: See 2. 5. Environmental/experimental conditions: 6. Describe any quality-assurance procedures performed on the data: The mass spectrometry uncertainties are reported for each value. All values standardized against international standard reference material IAEA S-1 Canyon Diablo Troilite (CDT). 7. People involved with sample collection, processing, analysis and/or submission: James Farquhar Amaury Bouyon

McKeldin Library Atlas Usage Dashboard
(2025) Anza Garcia, Jose Francisco; Budhathoki, Milan; Nealis, James
McKeldin Library's map collection includes over 750 bound atlases, spanning a wide variety of topics and geographic locations. Because these materials cannot be checked out by patrons, tracking their usage and deriving detailed analytics is inherently difficult. In response to this, we implemented a "no reshelving" rule that indicates patrons to leave any materials they use out, allowing for usage to be tracked in a spreadsheet when staff shelf these materials. Using this data, which has been collected since 2015, we created an interactive, web-based dashboard application to explore and communicate various usage metrics, including geographic location and atlas category. These metrics can be used in future acquisition and collection management decisions.

A Content Analysis of Engineering LibGuides, Research in Progress
(2025-06-17) DiCiesare, Leah; Weiss, Sarah
LibGuides, a content management system provided by the Springshare company, is a commonly used tool for aggregating library resources by topic. While their use is practically ubiquitous in academic libraries, the content, layout and pedagogical approach of these guides varies widely. Before making a concerted effort to update and improve the engineering LibGuides at our university, we are conducting a content analysis to discover current trends in the composition of engineering LibGuides at other R1 institutions. In this work in progress, we have started with an analysis of the Chemical Engineering guides to gain insight into their contents and make decisions to guide the further data collection of our entire data set. In addition to surveying the specific content included in these guides, we will analyze how it is presented pedagogically; whether it is user-centered or learner-centered. Our study considers LibGuides from 50 R1 institutions, including the top 20 from the US News and World Report 2023-2024 Best Engineering Schools and a random sample of 30 other institutions. Each guide analyzed was saved as a PDF in the summer of 2024 and uploaded to NVivo for coding of the layout, content, and pedagogy used in the guide. This presentation will discuss our findings thus far and how we will use this pilot analysis to move forward with the full analysis; in particular, the goal is to optimize the coding process and address any issues that arise and adjust our study accordingly. By examining the pedagogical approach behind these guides we can identify areas where they can be better aligned to meet the needs of our students, ensuring that resources are not only accessible but also supportive of their learning experience. This addresses Equitable Access to Information and Library Services and Transforming Libraries, which are both ALA Key Action Areas. In addition, by using a systematic method of analysis we are not allowing our personal beliefs to interfere with our research results.

A Brief History of STEM Libraries at UMD
(2025-06-11) DiCiesare, Leah
Library spaces, practices, and trends have changed dramatically since the University of Maryland (UMD) was founded in 1856. This new project is looking at how the STEM libraries at UMD started, changed, and came to be what they are today while also looking at the greater contexts of library trends. This short presentation will present a brief overview of the history of the STEM libraries at UMD and some major points of interest.
