Student workers are a well-established component of academic library operations. Recently, their traditional role has expanded to include responsibilities that were previously assigned to librarians, including in-person and virtual reference support. This trend has raised concerns about service quality and highlighted the importance of adequate training and evaluation for student employees. This case study outlines the training and assessment program for student employees working on Ask a Librarian, an academic consortial chat reference service in Ontario, Canada. Evaluations indicate that student assistants are less formal in their communication style, do not consistently perform a thorough reference interview, and deviate from some Reference and User Services Association (RUSA) best practices. However, students are consistently rated very highly by users in exit surveys. With a training program that addresses communication, in-depth reference interview techniques, and consistent follow-up and assessment, students are a viable option for staffing chat and can meet high service quality standards for reference service.  相似文献

ABSTRACT

As academic institutions continue to renovate and remodel existing libraries to include colocated services, it is important to understand how this new environment requires the redefining of traditional library roles and responsibilities. This case study examines how Delaware County Community College redefined reference and research service by transitioning to a triage reference model. This includes how information desk staff and student workers at a single service point determine when to refer users to librarians and how this model has evolved based on specific situations and experiences.  相似文献

Abstract

Explores virtual reference as a new career opportunity for librarians. Asks if this is a good, long career path, or if it will careen virtual reference librarians off into the slough of despond. The skills needed for the traditional reference librarian are compared to those needed by the virtual reference librarian; the challenges and advantages of working virtual versus traditional reference are identified; the types of questions and resources used in providing virtual reference service are discussed; and the types of interaction with the patrons are explored. The skills needed to manage and evaluate virtual reference services are also articulated.  相似文献

This article examines the process of researching, adapting, and implementing a text message reference service and the conclusions reached after nearly 10 months of continuous service. This experiment involved a single BlackBerry passed in a rotating schedule among librarians to gauge student interest in a text reference service. Although implementing this service allowed the library to be at the technological forefront, this is a service that would be better provided via a software interface. Furthermore, the text message reference service needed a stronger marketing campaign to make students aware of this option.  相似文献

To facilitate a comparison of reference services at academic and school libraries, a survey of resource use at school libraries was undertaken. The survey showed that electronic references sources are favored at all levels of schools. The resources used may be different, but the goal of the reference transaction is the same—to create a more information-literate student.  相似文献

The reference interview is integral to the success of the reference transaction. Thus, learning to conduct an effective reference interview is essential for library and information science students. Despite abundant literature on how to conduct the interview, little research exists on how well library and information science students are applying competencies associated with the reference interview, and how successful their reference interactions are. Through a survey reflection on a course-embedded assignment, this study examines reference success from the point of view of the library and information science student and their patrons. The results of the study have implications for library faculty and employers and reference managers.  相似文献

Summary

Increased student use of the Internet and declining reference desk statistics are factors encouraging academic reference librarians to look for new ways to reach patrons. Web-based customer contact center software gives librarians the tools to provide interactive, 24/7 reference service to Internet users. This article describes how the library at California State Polytechnic University, Pomona developed its live/web reference service. We discuss the factors that encouraged us to launch the service, the challenges that we encountered along the way, and examples of our experiences to date.  相似文献

The Internet is the research tool of first choice among today's library users. Libraries are responding by introducing a number of Internet-based reference services to meet the needs of these techno-literate users. Focusing on an academic library in the Caribbean, this article discusses the issues that privilege traditional over virtual reference and examines issues such as student information research skills, the physical format of the collection, levels of staffing, and the role of culture.  相似文献

SUMMARY

The Internet Public Library is an experimental educational initiative of the University of Michigan School of Information. The author, a Michigan alumna, argues that the Internet Public Library can play a role in the education of reference librarians, with particular attention to the traditional reference skills it fosters. She discusses her own experience with the IPL and QRC, its digital reference tool, as a library student, positing that the value of the IPL lies in the way it renders individual aspects of the reference process explicit and forces its users to examine them piece by piece.  相似文献

Abstract

Launching virtual chat reference services at Boatwright Library at the University of Richmond has been an interesting challenge of “trial and error” over the years. After trying several different software programs and staffing options, librarians have finally found a niche with AOL's Instant Messenger service. The first section of the article describes a path of experimentation, including early collaborations with the computing services help desk, staffing patterns within the library, technical and financial challenges with virtual reference software, and attempts to get students to use reference chat services. The second half of the case study describes the great success with AIM service in the past year, providing statistical information as well as coverage of training and guidelines, advertising, and staffing. This article touches on a number of themes, including the value of experimenting with a variety of chat reference software programs, and the need for library staff to stay current with new technologies.  相似文献

Summary

The Internet has brought great changes to reference services in academic libraries. One significant impact has been the growth and evolution of the reference librarian's role as teacher. This article reviews the literature on the librarian's increased teaching role with the emergence of the Internet, discusses the changing student populations who require a librarian's instruction and the skills that students need to achieve information literacy, and reviews how the Internet has affected current teaching strategies including classroom instruction, Web-based instruction, and efforts to integrate information literacy instruction into the curriculum. In addition, it also introduces emerging Internet technologies with their potential impact on teaching and instruction. The authors conclude that the reference librarian's teaching role will further increase with the development of information technologies.  相似文献

The reference librarian aims to know the reference collection like the back of his or her hand. This knowledge of knowledge can be characterized as encyclopedic, in that it enables the reference librarian to comprehend the unity that exists within the branches of knowledge—the subject categories as outlined in the Library of Congress (LC) classification and represented in the reference collection. Comprehending this unity further enables the reference librarian to make those intelligent leaps, uncanny connections, and creative combinations between subject categories, whether closely or distantly related or even entirely unrelated. This metaknowledge and the fluency with the collection it supports define at its most fundamental level what reference is and what reference does. Despite its ease, speed, and convenience, the algorithm is no replacement for the mind of the reference librarian. Critical acceptance of this fact is in evidence when the simple, spontaneous one-on-one encounter at the reference desk rather than the preplanned, required session in information literacy is understood as the primary locus of learning in the library. Reference librarianship with its modest accoutrements—the reference desk, the reference interview, the reference collection—is still most suitable to provide the kind of guidance every thinking student needs to rightly read and engage the authoritative works that make up the main collection.  相似文献

ABSTRACT

Utah State University has successfully implemented a service that incorporates e-mail reference and an appointment-based model. The advantages of the Term Paper & Research Assistance service are reviewed. The program incorporates a great deal of flexibility for the participating librarians and the clients they serve and eliminates the need for a “coordinator.” Use statistics and positive student feedback have underscored the service's potential for future growth.  相似文献

Within the past 10 years, commons have become increasingly prominent in academic libraries. Commons evolved out of the “library as a place” movement and stem from the digital revolution, increased emphasis on collaborative learning, and changing student habits and needs. The three levels of commons are information commons, learning commons, and the emerging virtual commons. Libraries implementing commons must consider the impact on reference services and staffing and be prepared for higher than anticipated use. Libraries should use both quantitative and qualitative assessment methods. Commons can revitalize the library by giving it a key role in reaching university strategic goals.  相似文献

ABSTRACT

A national survey of academic librarians was conducted to examine relationships among reference service staffing changes, reference service innovations, adoption of reference technology, library type and size, and service quality. Analysis of the 606 response sets reveals trends toward reduced use of librarians and increased use of student staff at in-person service points, widespread increases in appointment-based and self-service reference, intensive efforts to reduce demand for reference by improving library instruction, and general improvements in reference service quality. Factors strongly associated with decreases or increases in quality are discussed in detail and implications for reference managers are provided.  相似文献

Summary

Every reference encounter is an instructional encounter. Reference services to adult learners must be as flexible as the learners' technological savvy and learning styles. Furthermore, a variety of instructional methods must be used. This study presents survey results of a sample graduate student population which is outside the mainstream of traditional college students. We present a Close Encounter Model of reference services to meet this population.  相似文献
