Balancing Bananas: Collection Assessment of Patron‐Driven Acquisitions

The libraries in the University of Colorado (CU) System have been using patron‐driven acquisitions (PDA) to build a shared collection of e‐books for many years. This paper presents our experiences as both early adopters of PDA and libraries with longstanding PDA e‐book programs and describes an analysis of how PDA has impacted collections at each of the libraries in the CU System

Are E-Book Packages Overwhelming and Redefining Your Collection?

Most academic libraries offer numerous e-books alongside their print titles. Traditionally, print materials have been chosen by subject liaisons with input from departmental faculty, whereas e-books have been acquired en masse through large collection purchases, subscriptions, or PDA/DDA programs that include large numbers of discovery records. At Kraemer Family Library, the print budget is divided into subject areas using a formula that includes the number of students in a discipline, level of program (bachelor, master, or doctorate), number of faculty by discipline, and average cost of materials in a subject area. This budget breakdown is an attempt to balance the library’s collection so that it reflects the focus and emphasis of the curriculum being taught on campus. Beginning in 2012, the Kraemer Family Library at the University of Colorado Colorado Springs began participating in two PDA/DDA e-book programs. The library also began purchasing e-book packages that were either publisher or subject based. During this same time, the library continued to use a formula to allocate the library’s print budget. Because e-books were not purchased according to any allocation, and the library was beginning a process of weeding the print collection, an analysis of the effect of e-books on the overall collection was undertaken. The purpose of this analysis was to determine what metrics should be used to determine the impact of e-books on the overall collection and to analyze that data for overall impact on the collection

Exploring the Evidence in Evidence-Based Acquisition

This article explores the University of Colorado (CU) Libraries’ experiences with evaluating a patron-driven (PDA) program with Kanopy and an evidence-based (EBA) program with Alexander Street for streaming videos. The article includes a thorough comparison of EBA and PDA models, workflows, and outcomes. Three separately administered libraries within the CU system support campuses of different budgets, student and faculty demographics, programs, and exposure to streaming collections. Lessons in implementing and assessing streaming videos at each library and across the consortia are shared along with details on how to implement similar analysis at other libraries

Severe maternal morbidity associated with maternal birthplace in three high-immigration settings

BACKGROUND: Maternal mortality and morbidity vary substantially worldwide. It is unknown if these geographic differences translate into disparities in severe maternal morbidity among immigrants from various world regions. We assessed disparities in severe maternal morbidity between immigrant women from various world regions giving birth in three high-immigration countries. METHODS: We used population-based delivery data from Victoria; Australia and Ontario, Canada and national data from Denmark, in the most recent 10-year period ending in 2010 available to each participating centre. Each centre provided aggregate data according to standardized definitions of the outcome, maternal regions of birth and covariates for pooled analyses. We used random effects and stratified logistic regression to obtain odds ratios (ORs) with 95% confidence intervals (95% CIs), adjusted for maternal age, parity and comparability scores. RESULTS: We retrieved 2,322,907 deliveries in all three receiving countries, of which 479,986 (21%) were to immigrant women. Compared with non-immigrants, only Sub-Saharan African women were consistently at higher risk of severe maternal morbidity in all three receiving countries (pooled adjusted OR: 1.67; 95% CI: 1.43, 1.95). In contrast, both Western and Eastern European immigrants had lower odds (OR: 0.82; 95% CI: 0.70, 0.96 and OR: 0.64; 95% CI: 0.49, 0.83, respectively). The most common diagnosis was severe pre-eclampsia followed by uterine rupture, which was more common among Sub-Saharan Africans in all three settings. CONCLUSIONS: Immigrant women from Sub-Saharan Africa have higher rates of severe maternal morbidity. Other immigrant groups had similar or lower rates than the majority locally born populations
