This paper discusses how the William G. Squires Library conducted a usability study on their LibGuides to identify student design preferences. The results of the study support previous research concerning best practices for LibGuide creation. This paper offers insight into how librarian-centric design hinders student success and provides suggestions for how to best develop a student-centric template design that offers consistency and increased user proficiency across all guides.

While usability tests have been helpful in evaluating the success or failure of implementing discovery layers in the library context, the focus of usability tests has remained on the search interface rather than the discovery process for users. The informal site-‐ and context specific usability tests have offered little to test the rigor of the discovery layers against the user goals, motivations and workflow they have been designed to support. This study proposes hierarchical task analysis (HTA) as an important complementary evaluation method to usability testing of discovery layers. Relevant literature is reviewed for the discovery layers and the HTA method. As no previous application of HTA to the evaluation of discovery layers was found, this paper presents the application of HTA as an expert based and workflow centered (e.g., retrieving a relevant book or a journal article) method to evaluating discovery layers. Purdue University's Primo by Ex Libris was used to map eleven use cases as HTA charts. Nielsen's Goal Composition theory was used as an analytical framework to evaluate the goal charts from two perspectives: a) users' physical interactions (i.e., clicks), and b) user's cognitive steps (i.e., decision points for what to do next). A brief comparison of HTA and usability test findings is offered as a way of conclusion. [ABSTRACT FROM AUTHOR]

An introduction is presented in which the editor discusses various reports published within the issue which include the analysis of electronic book usage in interdisciplinary research collection, the holistic view of electronic book acquisition, and the optimization for electronic resources.

This paper examines publisher ebook package use in the OhioLINK academic library consortium between 2007 and 2017 alongside use of the same titles at individual institutions. With nearly 100,000 titles acquired over 10+ years from three publishers and available to users at more than 90 institutions, the picture of ebook use this study presents is unique in its breadth and scope. The data show that, consortiumwide, close to 100 percent of titles were used, with their initial use overwhelmingly taking place within one year of their publication date. At individual institutions, the rate of use was far lower and never exceeded the rate of use of print books at the author's own institution. These findings have important implications for how institutions approach ebook acquisition to maximize rate of use of ebook collections. [ABSTRACT FROM AUTHOR]

This paper presents an analysis of e-book usage in one interdisciplinary research collection, for library and information science (LIS), at a large research institution. Drawing from the social sciences, humanities, and computer science, LIS exemplifies the challenge of analyzing use of interdisciplinary collections that cut across Library of Congress (LC) class ranges normally used to analyze disciplinary differences in the existing literature. The analysis also explores use factors beyond LC class that usage studies rarely examine, including genre and audience level, and changes in use over time across categories. This study contributes both to understanding the usage of LIS e-books as an exemplary interdisciplinary collection and to developing options for analyses of e-book collections that maximize the utility of usage reports despite their challenges. As e-book collections mature and the utility of comparing used versus unused titles wanes, such strategies will become necessary to make more nuanced decisions for e-book collections.

Patron-Driven Acquisitions (PDA) is a new model used for e-book acquisition by academic libraries. A key component of this model is to make records of e-books available in a library catalog and let actual patron usage decide whether or not an item is purchased. However, there has been a lack of research examining the role of the library catalog as a tool for e-book discovery and use in PDA. This paper presents a case study of using PDA for e-book acquisition in an academic library, with a focus on the role of the library catalog in this purchasing model. The implications and challenges are also discussed. [ABSTRACT FROM AUTHOR]

Demand-Driven Acquisition (DDA) has been commonly adopted by academic libraries in the United States for acquiring e-books in recent years. Implementation of the e-book DDA model varies by library. This paper introduces and demonstrates a scenario analysis approach for libraries to evaluate, identify, and select a DDA plan that works best for them based on their DDA program data. This approach helps address some key questions facing libraries with a DDA e-book program: How may a DDA program be evaluated under different scenarios? Does a short-term loan (STL) option make sense? And, is the current DDA implementation a good fit for the library? The implications and related issues are discussed. [ABSTRACT FROM AUTHOR]

What is the current state of mobile services among academic libraries of the country's top 100 universities, and what are the best practices for librarians implementing mobile services at the university level? Through in--‐depth website visits and survey questionnaires, the authors studied each of the top 100 universities' libraries' experiences with mobile services. Results showed that all of these libraries offered at least one mobile service, and the majority offered multiple services. The most common mobile services offered were mobile sites, text messaging services, e--‐books, and mobile access to databases and the catalog. In addition, chat/IM services, social media accounts and apps were very popular. Survey responses also indicated a trend towards responsive design for websites so that patrons can access the library's full site on any mobile device. Respondents recommend that libraries considering offering mobile services begin as soon as possible as patron demand for these services is expected to increase. [ABSTRACT FROM AUTHOR]

Academic libraries are increasingly purchasing electronic books (e-books) via demand driven acquisitions (DDA) programs. However, there is no guarantee about the quality of DDA titles. This is especially true for consortially managed DDA pools or when pools include all titles from selected publishers. This study analyzes data from EBSCO’s GOBI acquisitions platform to assess the quality of the pool and purchased titles from the Colorado Alliance of Research Libraries (CARL) publisher-based DDA program. Results showed that most available and selected titles were appropriate for academic libraries. Popular and lower level academic titles made up a relatively small portion of the DDA pool but were selected at a proportionally higher rate than other titles. The DDA pool was weighted towards titles that had been previously purchased by few GOBI libraries, but users tended to select titles that had been purchased by more GOBI libraries. Implications of these results are discussed from the point of view of a consortium member library using the DDA program as a supplement to its broader collections of print and e-books.

Many studies have tried to identify factors that make electronic books (e-books) in academic libraries more likely to be used. For instance, are demand-driven acquisitions used more than titles in packages? Are e-books in the sciences used more than e-books on art? Most of these studies are limited to one or two variables. This study introduces logistic regression, which can incorporate multiple variables to determine which factors are the most useful in predicting e-book usage. The variables considered in this study are LC class, university press or other publisher and platform. In the collection studied, the classes with the highest odds of being used were A (General Works), followed by F (History of the Americas), H (Social Sciences) and Q (Math and Science).

This article outlines a study assessing and comparing the rate of use of nonreference print and electronic book collections acquired during the same time period at one academic library. Rate of use was examined for both collections by discipline and method of acquisition. The author found that 74 percent of print titles acquired in 2008–2009 had been used within their first six years in the collection, and that 27 percent of print books acquired between 2008 and 2014 had been used between July 2013 and November 2014. By contrast, only 12 percent of the e-books acquired between 2008 and 2014 were used during the same 17-month period. The author examines how different print and electronic collection development models might affect monograph use in academic libraries within the context of previously published research.

ACRL’s “2016 Top Trends in Academic Libraries” noted a “shift to the incorporation and integration of more continuous, ongoing, flexible, and sustainable review of collections,” and “an increasing need” to align collection development with “institutional research and curricular requirements.” This article describes these trends playing out at a top-ranked research library. Given the library’s long history of collecting print books, the article examines the monographic acquisitions program from multiple angles, including circulation, expenditures, approval plans, and e-book usage. There are also suggestions for additional metrics to evaluate collections as a service, as well as questions posed to frame an ongoing research and assessment agenda. The models described in this case study and the proposed research and assessment agenda can be adapted by other academic libraries, both to fit local institutional needs and as collection development and “collections as a service” are increasingly realized within interinstitutional collaborative networks.

Demand-driven acquisitions (DDA) programs have become a well-established approach toward integrating user involvement in the process of building academic library collections. However, these programs are in a constant state of evolution. A recent iteration in this evolution of ebook availability is the advent of large ebook collections whose contents libraries can lease, but not own only if they choose to do so. This study includes an investigation of patron usage and librarian ebook selection by comparing call number data generated by usage of three entities: (1) an ebrary PDA; (2) Academic Complete, which is a leased collection of e-books; and (3) subject librarian selections based on the YPB approval plan at Iowa State University. The context is provided through a description of the development and evolution of demand driven acquisitions programs with an analysis of where libraries have been and where they are going with enhancing the collection development in academic libraries.

Despite the prevalence of academic libraries adopting web-scale discovery tools, few studies have quantified their effect on the use of library collections. This study measures the impact that EBSCO Discovery Service has had on use of library resources through circulation statistics, use of electronic resources, and interlibrary loan requests. Additionally, the data were compared against data from similar academic libraries without discovery systems. Findings include a strong growth in e-journal use but a sharp decline in circulation statistics. Implications of discovery on use of the print collection are discussed along with suggestions for improving integration of book and article data. [ABSTRACT FROM AUTHOR]

Academic libraries continue to face funding pressures compounded by the need to provide students with access to electronic resources, both in journal and book formats. With space constraints and the need to repurpose library space to other uses, libraries must carefully examine the move to e-only formats for books to determine if the format makes reasonable economic sense. A survey conducted at Auburn University at Montgomery (AUM) has confirmed for academic libraries the work of Gray and Copeland on e-books being more expensive than print for public libraries. For AUM, the mean cost for an e-book is significantly higher than for the print counterpart of that title. The cost differentials between the two formats show e-books as being consistently higher than print in initial price. This consistency holds true across all LC classifications, regardless of whether or not the title is published by a university press or a commercial press. [ABSTRACT FROM AUTHOR]
