This thesis deals with one of the main questions within information science: The question about controlled and uncontrolled vocabulary and which of the two that are most effective when it comes to retrieve relevant information from electronic databases. The method used here is literature studies. I have described and examined five empirical studies which has been done in purpose to compare the effectiveness in retrieval with controlled and uncontrolled vocabulary, in the way they are used in retrieval of information in databases. The studies I have examined have also used recall and precision as a value to measure the effectiveness of retrieval. The studies which I have chosen is also limited to deal only with studies that have been done in bibliographic databases.

The aim of this master thesis is to explore what role libraries play in the educational process for university students suffering from dyslexia. The question at issue is whether the library is able to meet the needs of students who have difficulty in using the libraries main resource, i.e. printed documents and information in written form. An often expressed view indicates that the modern library creates a lot of obstacles for dyslectic students. The method used is a literature study followed by an empirical study in which interviews were conducted with four students suffering from dyslexia and studying at two different universities and using different libraries.

The subject of this thesis is to ascertain the task of the public library in Swedish society today according to the employer, that is the State and the municipalities, and according to the public library itself. The thesis also tries to establish as to what extent these different actors share the same view of the task. To this purpose I have studied the library law, the target reports of municipal authorities and public libraries, and made interviews with public library representatives during the autumn of 2001. The particular consideration of this paper is whether the task is being described in active, culture making terms or in passive, service functionary terms. Initially, I describe the task according to the library law.

The wide spread of the Internet and new information technologies in recent years has come to effect how libraries manage and disseminate information. Search engines like Google are widely used by people who often find the information retrieval systems of libraries to be too complicated. In 2004 Google announced plans to digitise five major library collections. Organisations representing the publishing industry and authors have since then filed lawsuits against Google claiming that Googles scanning of library books infringe the rights holders copyright. Due to Googles potential impact on libraries this thesis aims to examine how Googles digitisation project, Google Book Search, has been received in the library community.

Information overload occurs when the amount of information exceeds the individual s capacity to efficiently process and use the information available. In this situation information instead of being an asset becomes a load. This interview study deals with college students experiences of information overload when working on their thesis. Focus lies on use of Internet based information resources. The main result was that the students experienced information overload in specific situations and steps of the process.

Fountain of Knowledge? The Changing Role of the Library at the Upper Secondary School Level. There have been many changes in the Swedish society in general, and in the school system and hence the school library in particular during the last decade. The aim of this master thesis is then to study what students at the upper secondary school level consider to be the optimal school library to meet their specific information needs at school. In addition to and in comparison with this, the aim is also to study the present conditions of the upper secondary school library as described in documents, reports and other studies in this field.

The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and information science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and information science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.

The aim of this essay has been to study six female seniors use and view of the library and its roles. The two Danish scientists Jochumsen and Rasmussen talk about the library in terms of a social center, cultural center, knowledge center and information center. Depending on what lifestyle the seniors belong to in the social room, they use the library differently. The social room consists of four lifestyles, north-west, north-east, south-west and south-east. The things that are important to consider in order to be able to place each senior within the different lifestyles are education level, economic standard, interests and so forth.

In the last few years there has been an ongoing debate concerning the methods of assessing the quality of public libraries and their services. This study investigates the opinions and needs of the users at four different public libraries in Malm : the local libraries in Bellevueg rden, Limhamn, and Kirseberg, and the main library in central Malm . The purpose was to find out whether different user groups display different patterns in their library use and, in addition, to identify what library services they prefer. The data were collected through interviews with users and librarians, and by means of a user survey ccarried out at the four libraries. The results indicate that certain differences in the usage patterns do exist between the main library and the local libraries.

The purpose of this master thesis is to investigate what the work situation of children's librarians looks like in the year 2000, after the changes in society which took place since the 1980's. Did the tasks of children's librarians change during the nineties, and if so, in what way and why have they changed? Which new knowledge needs emerged for children's librarians during the nineties, and what was the cause of these new needs? Finally I want to know which needs for professional development arose, and how these needs are fulfilled. The thesis is based on qualitative interviews with children's librarians, library managers, library consultants, one representative of the Swedish school of Library and Information Studies and one member of SAB's children and youth committee. The study reveals that the identity of children's librarianship is strongly associated with the stimulation of language and reading.

The history of books and libraries in the Philippines starts after the arrival of the Spaniards in 1521. During the Spanish era, most of the libraries were established through the religious orders to support their own religious mission. The Americans came in the beginning of the 20th century and have had a decisive influence on the education system and the development of libraries in the Philippines. For the analysis, I have used the models of Michael H. Harris and Magnus Torstensson in their studies of library development.

We studied the understanding of public librarians of the required qualifications for a public librarian, what these qualifications embody and how they should be used, and if there are any differences between geographic regions. We also compared our results to the Library Code, which describes the responsibilities of the public libraries. To complete our study, we interviewed fourteen public librarians at eight different public libraries located in both urban and rural areas in Sweden. Our results showed that even though the qualifications specified by the Library Code were identical, they were emphasized and used differently by the public libraries included in our study. This illustrates that the public libraries prioritize and focus differently on the various aspects of the Library Code.

The aim of this thesis is to study how librarians in Swedish libraries perceive the task of mediating fiction. What are the librarians private relationships to fiction and how do they perceive the position of fiction in contemporary society? What views have they developed of the borrowers approach to fiction and how do they perceive the borrowers increasing influence in the library? How do librarians prioritise and which principles form the basis for their purchase of fiction? How do they categorise fiction in the library and how much do economic and political factors influence the decision making process for the purchase of fiction? Finally, how do they define their roles as mediators of fiction and which strategies do they adopt to communicate which literature the library has to offer? The material used in this study was acquired using a qualitative interview technique in which six librarians with experience of literature mediation partook..

The aim of this study is to investigate variations of conceptions among prison librarians, concerning mediation of information from an ethical perspective. We have performed interviews with nine librarians and used the phenomenographic approach when analyzing the material. Sixteen categories of conceptions were found, distributed on four aspects of the phenomenon, the act of mediating information to inmates. The results show a variety of conceptions among the librarians. The four aspects cover conceptions about the inmates as users of the library services in prisons, conceptions about the information need of the inmates, conceptions concerning policies, guidelines and laws and conceptions about information access in the prisons.
