This thesis presents a new way of providing library users with reference services, namely chat (text based digital reference service in real time). Our research questions focus on the role of reference service, a comparison of chat reference to other reference forms, and the interest for real-time, digital reference. Our literature review covered the areas of digital reference and reference theory, the results of which showed that an ongoing debate hardly exists among Swedish librarians on the topic of reference work. We interviewed librarians from the three different Swedish chat reference projects existing at the time of our study. Most interviewees were very positive about chat reference.

The aim with this thesis is to investigate how librarians experience communication with children in reference interviews. In today?s interactive community it is meaningful to study how children communicate with the librarian in virtual reference interview as well as in ordinary reference interviews in physical libraries. Focus has been on finding out what children ask about and how they are asking in virtual reference interviews and in ordinary reference interviews, what type of information needs the children have. The study also focuses on which barriers there can be in reference interviews.

The aim and goal of this work has been to design and implement a voltage reference network for a 12-bit PSAADC, Parallell Successive Analog to Digital Converter. A chip containing the design has been sent away for fabrication. Because of the long processing time, no measurement data are presented. The main specifications for the voltage reference generator is to generate stable reference voltages with low noise and a good PSRR. Efforts has also been made to minimize the power consumption..

This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.

The purpose of this Masters thesis is to study how librarians experience reference work. We wanted to get a better understanding about librarians assignments through the study. We chose to limit the study to public libraries, and to the south of Sweden. The questions used in our study are: How do librarians interpret the conception of reference work? What values do librarians have concerning reference work? How do librarians experience reference work? How do librarians look at different roles in reference work? We chose to use a fenomenographically inspired method.

This thesis examines the subject of reference interviews and the ways librarians form an opinion of users information needs. Using literature and interviews with three librarians I look at the questions below: - Why and when are reference interviews needed? - What significance do they have? - What ideas exist about the performance of reference interviews? - Are there any differences in librarians views of the questions above compared to views in the literature? Results from literature studies and interviews show that reference interviews can be important when librarians try to find out more about users information needs. However its neither necessary nor possible to analyse all reference questions. Librarians therefore need to determine if a reference interview is needed or not.

The aim of this master thesis is to study the students usage and experiences of the reference services at the university library at Linköping University. The four questions that I seek answers to are: - What kind of help do the students most often ask for at the reference desk? - To what extent do the students use the reference services for their studies? - What are the students experiences of the help they receive at the reference desk? - What are the students experiences of the treatment they receive from the librarians at the reference desk? I have studied literature that describes reference work and evaluation of reference work. I have also studied Christian Grönroos theory of service quality. I have distributed questionnaires to students at Linköping University.

The population over 65 years of age is increasing and health in elderly has been a subject of research for decades but voice function and vocal health has not been prioritized. The purpose of this study is to obtain reference value for the Swedish version of Voice Handicap Index (RHI) and the Throat Scale among people over 65 years of age and assess voice function and vocal health for this age group. The questions were as followed:1) What is the reference value of RHI for people over 65 years of age? 2) What is the reference value of the Throat Scale for people over 65 years of age? 3) Is there a correlation between a self-rated VA-scale on the perceived degree of voice problems, and the self-rated RHI-/Throat Scale result? 4) Does age, gender or previous profession matter for the self-perceived voice?In total 100 individuals participated in the study, 50 women and 50 men, between 65 and 92 years old. The reference value of RHI for people over 65 years of age was 13,4 points and the reference value for the Throat Scale was 7,7 points.

This two years master?s thesis in Library and Information Sciences aims to investigate and put the services of 118100 Svar På Allt (SPA, an SMS mobile question and answer service) and Fråga biblioteket (FB, a library operated e-mail reference service) into the context of the reference encounter. Questions sent to SPA and their subsequent answers are analysed, and part of these questions are forwarded to FB for comparative studies. Both of the formats are compared to the reference encounter as a whole. The framing of the question originates in the assumption that there may be a need for further negotiation of the questions submitted to the aforementioned formats.

The purpose of this master thesis is to investigate the differences between the traditional way of conducting a reference interview and the electronic way. The main questions of this thesis are: How does the electronic reference interview appear in comparison to the traditional one? How do the librarians experience the differences? Is quality affected in the electronic reference interview? Examples from Fråga biblioteket Ask the Library have been used in this study. The method used in the investigation is based on qualitative interviews in combination with studies of relevant and recent literature. The librarians interviewed all have experience from both traditional and electronic reference work.

The aim of this master?s thesis is to examine the virtual reference service Ask the Library [Bibblan svarar] from a postmodern perspective. Ask the Library is a Swedish online reference service that is run by the country?s public libraries. The postmodern theories of Jean-François Lyotard are used to study how information is managed and transmitted within the service.

The purpose of this Master thesis is to compare the perception and significance of reference work in two countries, Sweden and Germany. This will be achieved by means of a literature review of previous research literature and public documents and a content analysis of articles from two library journals.A first step was to examine the historical development of reference work in the selected countries. In connection with this there proved to be distinct phases in the discussion regarding reference work. These phases with their specific discourses, themes and emphases reflected and thus later were confirmed in the second part of the study.The results show that despite some similarities there are also quite a few differences in how reference work is perceived in both countries. For Sweden, the idea of reference work was introduced relatively early.

This is a study on the electronic reference work of some Swedish university and university college libraries. The purpose of the study has been to find out how the service works at the different libraries, to study the electronic reference interview and to find what is important when you start a new electronic reference service in the light of Brenda Dervin's sense-making theory study. Furthermore, we examine the aims of the electronic services offered and the differences between electronic and traditional reference interviews. In the background to the study we place electronic reference services in a context by describing the role of information technology and electronic mail in the libraries. The electronic reference interview is studied with the help of literature on the traditional reference interview.

The aim of this Masters thesis is to understand how librarians develop their reference service. The purpose was to find patterns in how librarians work with reference questions. As a theoretical framework we have used research in the reference field. Where do the skills of the search process come from: education or experience? Answers were sought to the following questions: - How different are the search process in practice compared to theory? - Which similarities and differences are there among the informants? - How important was the education in comparison to the knowledge about the libraries collections? - How did the changes in the school system in 1993 influence reference education and what could the consequences be to the reference knowledge among librarians? We sent out a question form and a search question which was answered by 12 librarians in university and university college libraries.
