Objective: Clinical and research usefulness of articles can depend on image quality. This study addressed whether scans of figures in black and white (B&W), grayscale, or color, or portable document format (PDF) to tagged image file format (TIFF) conversions as provided by interlibrary loan or document delivery were viewed as acceptable or useful by radiologists or pathologists. Methods: Residency coordinators selected eighteen figures from studies from radiology, clinical pathology, and anatomic pathology journals. With original PDF controls, each figure was prepared in three or four experimental conditions: PDF conversion to TIFF, and scans from print in B&W, grayscale, and color. Twelve independent observers indicated whether they could identify the features and whether the image quality was acceptable. They also ranked all the experimental conditions of each figure in terms of usefulness. Results: Of 982 assessments of 87 anatomic pathology, 83 clinical pathology, and 77 radiology images, 471 (48%) were unidentifiable. Unidentifiability of originals (4%) and conversions (10%) was low. For scans, unidentifiability ranged from 53% for color, to 74% for grayscale, to 97% for B&W. Of 987 responses about acceptability (n=405), 41% were said to be unacceptable, 97% of B&W, 66% of grayscale, 41% of color, and 1% of conversions. Hypothesized order (original, conversion, color, grayscale, B&W) matched 67% of rankings (n=215). Conclusions: PDF to TIFF conversion provided acceptable content. Color images are rarely useful in grayscale (12%) or B&W (less than 1%). Acceptability of grayscale scans of noncolor originals was 52%. Digital originals are needed for most images. Print images in color or grayscale should be scanned using those modalities. [ABSTRACT FROM AUTHOR]

At East Carolina University (ECU), Joyner Academic and Laupus Health Sciences Libraries collaborated on a shared Neuroscience collection development policy, primarily as a reaction to state-level budget cuts. The policy aims to limit duplication in purchases at each library location but also describes the materials that are most appropriate for selection by each library and explores the usefulness of e-book purchases as a cost-saving measure. The result of this collaborative effort is a comprehensive neuroscience collection for ECU's libraries. [ABSTRACT FROM AUTHOR]

Creating a learnable, effective, and user-friendly library Web site hinges on providing easy access to search. Designing a search interface for academic libraries can be particularly challenging given the complexity and range of searchable library collections, such as bibliographic databases, electronic journals, and article search silos. Library Web designers must decide whether to present users with a single search interface-one that searches across content silos by default-or to offer an interface that exposes the various silos available. Designers must also contend with the user's entire search experience and determine how search should appear on the library home page as well as in global navigation systems. In the spring of 2010, the North Carolina State University Libraries sought to answer search design questions for an upcoming Web site design effort. The Libraries evaluated two different search interfaces to determine whether a tabbed search approach with options to pre-select silos is an effective design for end users. Findings show that a tabbed search interface is an effective design device for presenting multiple silos. This study outlines the methods the North Carolina State University Libraries used to conduct usability testing as well as observations, findings, and recommendations about effective design of search on academic library Web sites.
