Health Sciences Librarians' Research on Medical Students' Use of Information for Their Studies at The Medical School,University of Queensland,Australia

This study reports the findings of research undertaken by health sciences librarians at the University of Queensland Library into how medical students use information for their studies, particularly resources and services provided by the Library. The methods utilized were an online survey and focus groups. Results indicated that students favor print resources over electronic, value accessing resources on a one-stop basis, and prefer training to be delivered flexibly. The implication of these results for future resource selection, service provision, and instructional design and delivery is discussed.     

Wired New Jersey: Q and A NJ

SUMMARY

Q and A NJ is New Jersey's virtual reference service. Available 24 hours a day, seven days a week, and free to all New Jersey residents, the service provides online reference assistance in real time from librarians across the state. New Jersey was the first state in the country to offer such service. This article looks at the history of the service, what it's like to be a virtual librarian, and presents a brief survey of the librarians participating in Q and A NJ.     

An Exploration of Indexed and Non-Indexed Open Access Journals: Identifying Metadata Coding Variations

The intent of this investigation was to learn what factors may have contributed to low usage of a small set of reputable open access scholarly journals, as evidenced in graduate student reference lists. Inquiry into differences among open access sources referenced between 2005 and 2014 revealed that non-indexed journals were being used notably fewer times than their commercially indexed counterparts. A comparison of HTML source code between indexed and non-indexed journals illustrated that certain metadata and other coding features may have affected the visibility of non-indexed journal content. The study suggests to librarians the presence of less visible empirical literature on the web and to smaller, independent academic publishers, the need to apply better quality metadata and optimization strategies to their open access journal content.

Performance of conceptual framework elements for the retrieval of qualitative health literature: a case study

Objective:A growing volume of studies address methods for performing systematic reviews of qualitative studies. One such methodological aspect is the conceptual framework used to structure the review question and plan the search strategy for locating relevant studies. The purpose of this case study was to evaluate the retrieval potential of each element of conceptual frameworks in qualitative systematic reviews in the health sciences.Methods:The presence of elements from conceptual frameworks in publication titles, abstracts, and controlled vocabulary in CINAHL and PubMed was analyzed using a set of qualitative reviews and their included studies as a gold standard. Using a sample of 101 publications, we determined whether particular publications could be retrieved if a specific element from the conceptual framework was used in the search strategy.Results:We found that the relative recall of conceptual framework elements varied considerably, with higher recall for patient/population (99%) and research type (97%) and lower recall for intervention/phenomenon of interest (74%), outcome (79%), and context (61%).Conclusion:The use of patient/population and research type elements had high relative recall for qualitative studies. However, other elements should be used with great care due to lower relative recall.
