Leveraging Use‐by‐Publication‐Age Data in Serials Collection Decisions

Traditionally, usage figures for electronic serials have lumped all years of publication together. New tools give librarians information about usage according to the year of publication. They allow us to analyze the usage of current material separately from usage of content published in prior years. The relative value of current subscriptions and backfiles has important collection development implications. For example, many libraries subscribe directly to titles that are offered in aggregated databases, but with embargoes. The relative value of current content distinguished from prior years may be useful in reevaluating such subscription decisions. This paper discusses tools and techniques for analyzing usage by year of publication according to several measures—including COUNTER’s JR5 report, Google Analytics, ILL reports, and token reports, and discusses how librarians can use these tools to aid in decision‐making about serials collection development decisions

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

The Library Never Closes: Assessing Resources and Services After a Crisis

There are different ways to interpret the statement, “the library never closes.” One interpretation is that the library as a place and a building is so vital to a university that it cannot close under any circumstances. At the University of Memphis (UM), one of the universities included in this study, the McWherter library did not close, even in March 2020 when fear and uncertainty around the COVID-19 pandemic were at their height. The University of Colorado Colorado Springs (UCCS) and Illinois State University (ISU), the other two institutions included in this study, closed their buildings in March and stayed closed into the summer. A second interpretation of “the library never closes” is that the library is more than a place or building. The library is a collection of resources, a set of services, and a group of people who can operate independently of the building. As long as it continues to serve its users, the library remains open even when its doors are closed. This paper uses data to examine the extent to which three university libraries were able to continue serving library users despite the disruptions of the COVID-19 pandemic. The data cover various aspects of library collections and services: physical checkouts, research services, instruction, website visits, discovery service sessions, electronic serials, electronic books, and streaming videos

The concluding chapter: Recircumscription of Goodenia (Goodeniaceae) to include four allied genera with an updated infrageneric classification

© 2020. Close scrutiny of Goodenia (Goodeniaceae) and allied genera in the \u27Core Goodeniaceae\u27 over recent years has clarified our understanding of this captivating group. While expanded sampling, sequencing of multiple regions, and a genome skimming reinforced backbone clearly supported Goodenia s.l. as monophyletic and distinct from Scaevola and Coopernookia, there appears to be no synapomorphic characters that uniquely characterise this morphologically diverse clade. Within Goodenia s.l., there is strong support from nuclear, chloroplast and mitochondrial data for three major clades (Goodenia Clades A, B and C) and various subclades, which lead to earlier suggestions for the possible recognition of these as distinct genera. Through ongoing work, it has become evident that this is impractical, as conflict remains within the most recently diverged Clade C, likely due to recent radiation and incomplete lineage sorting. In light of this, it is proposed that a combination of morphological characters is used to circumscribe an expanded Goodenia that now includes Velleia, Verreauxia, Selliera and Pentaptilon, and an updated infrageneric classification is proposed to accommodate monophyletic subclades. A total of twenty-five new combinations, three reinstatements, and seven new names are published herein including Goodenia subg. Monochila sect. Monochila subsect. Infracta K.A. Sheph. subsect. nov. Also, a type is designated for Goodenia subg. Porphyranthus sect. Ebracteolatae (K. Krause) K.A. Sheph. comb. et stat. nov., and lectotypes or secondstep lectotypes are designated for a further three names

Phylogeny, Adaptive Radiation, and Historical Biogeography in Bromeliaceae: Insights from an Eight-Locus Plastid Phylogeny

Premise: Bromeliaceae form a large, ecologically diverse family of angiosperms native to the New World. We use a bromeliad phylogeny based on eight plastid regions to analyze relationships within the family, test a new, eight-subfamily classification, infer the chronology of bromeliad evolution and invasion of different regions, and provide the basis for future analyses of trait evolution and rates of diversification. Methods: We employed maximum-parsimony, maximum-likelihood, and Bayesian approaches to analyze 9341 aligned bases for four outgroups and 90 bromeliad species representing 46 of 58 described genera. We calibrate the resulting phylogeny against time using penalized likelihood applied to a monocot-wide tree based on plastid ndhF sequences and use it to analyze patterns of geographic spread using parsimony, Bayesian inference, and the program S-DIVA. Results: Bromeliad subfamilies are related to each other as follows: (Brocchinioideae, (Lindmanioideae, (Tillandsioideae, (Hechtioideae, (Navioideae, (Pitcairnioideae, (Puyoideae, Bromelioideae))))))). Bromeliads arose in the Guayana Shield ca. 100 million years ago (Ma), spread centrifugally in the New World beginning ca. 16-13 Ma, and dispersed to West Africa ca. 9.3 Ma. Modern lineages began to diverge from each other roughly 19 Ma. Conclusions: Nearly two-thirds of extant bromeliads belong to two large radiations: the core tillandsioids, originating in the Andes ca. 14.2 Ma, and the Brazilian Shield bromelioids, originating in the Serro do Mar and adjacent regions ca. 9.1 Ma

Adaptation and Convergent Evolution within the Jamesonia-Eriosorus Complex in High-Elevation Biodiverse Andean Hotspots

The recent uplift of the tropical Andes (since the late Pliocene or early Pleistocene) provided extensive ecological opportunity for evolutionary radiations. We test for phylogenetic and morphological evidence of adaptive radiation and convergent evolution to novel habitats (exposed, high-altitude páramo habitats) in the Andean fern genera Jamesonia and Eriosorus. We construct time-calibrated phylogenies for the Jamesonia-Eriosorus clade. We then use recent phylogenetic comparative methods to test for evolutionary transitions among habitats, associations between habitat and leaf morphology, and ecologically driven variation in the rate of morphological evolution. Páramo species (Jamesonia) display morphological adaptations consistent with convergent evolution in response to the demands of a highly exposed environment but these adaptations are associated with microhabitat use rather than the páramo per se. Species that are associated with exposed microhabitats (including Jamesonia and Eriorsorus) are characterized by many but short pinnae per frond whereas species occupying sheltered microhabitats (primarily Eriosorus) have few but long pinnae per frond. Pinnae length declines more rapidly with altitude in sheltered species. Rates of speciation are significantly higher among páramo than non-páramo lineages supporting the hypothesis of adaptation and divergence in the unique Páramo biodiversity hotspot
