Item A Study on Electronic Services Provided by the National Library of Sri Lanka(Department of Library and Information Science, University of Kelaniya, Sri Lanka, 2023) Thilakarathna, M.D.B.C.M.; Wanigasooriya, PriyanwadaElectronic services are information services in electronic format that are handled by a computer device and encoded for handling. The National Library of the world provides a wide range of electronic library services to users. Today, the National Library of Sri Lanka provides e-library services in addition to traditional library services. With the COVID pandemic, there has been a rapid increase in the number of Electronic library services provided by the National Library of Sri Lanka. Today, there are 33 Electronic services provided by the National Library. It remains to be seen whether users will benefit from these services. For this research, numerous studies have studied users' behavior, usage of print resources, evaluation of electronic library services, and evaluation of library services using serverQUAL and LibQUAL, analyzing national and global research publications and printed and electronic media. The primary objectives of this study are four-fold. Firstly, it aims to identify and catalog the various electronic services that have been introduced by the National Library. Secondly, the study seeks to conduct an in-depth analysis of the current usage and adoption of these E-services among library users. Thirdly, it aims to identify any potential vulnerabilities or shortcomings in the existing E-services to ensure their optimal functionality and security. Lastly, the study endeavors to propose practical and effective measures that can be implemented to expand and enhance the range and quality of E-services provided by the National Library. By pursuing these objectives, the study aims to contribute to the overall improvement and advancement of library services in the digital age. This study has used a web-based survey methodology to study what electronic library services are available to readers, using a list of 59 items. In addition, two online questionnaires have been submitted to National Library users and National Library staff to study the status and use of Electronic services provided by the National Library. Based on the web-based survey methodology and the dual questionnaires, the National Library identifies the weaknesses in the electronic services provided and presents the results in simple frequencies and percentages. The research revealed that the National Library of Sri Lanka provides 69.49% of Electronic library services. Research has shown that 72% of respondents use the Electronic services provided by the National Library, and 28% of respondents do not use the electronic library services provided by the National Library. The research proposes the introduction of state-of-the-art electronic library services, features for the website, publicity of library services among the people of the country, and workshops and projects for staff IT knowledge and development.Item Improving Sinhalese Personal Name Authority Control in Sri Lankan Online Public Access Catalogues (OPACs)(Department of Library and Information Science, University of Kelaniya, Sri Lanka, 2023) Wanigasooriya, PriyanwadaPersonal names play a crucial role in locating books systematically and identifying individuals. Previous studies have emphasized that searching by an author's name is the most common method used by library users in automated systems. The objective of name authority control is to enhance searching and browsing capabilities by ensuring the accurate retrieval of all works associated with an individual, including variations of personal identity such as pseudonyms and family names. Unfortunately, Sinhalese personal names are quite common. These variations negatively impact information retrieval quality, the linking of related resources, and copyright management. Rather than that misspelled names and duplicated same name in data entries can be easily detected by machines. However, other variations, such as an author using their full name or an abbreviated form, one person having different name forms, or multiple people sharing the same name, cannot be easily identified by machines. Therefore, libraries employ authority control files for personal names, using a single, distinct spelling of the personal name (known as the heading) for each library material. The objective of this survey was to develop an automated authority file capable of accurately identifying books based on specific personal names. In pursuit of this goal, a statistical approach was utilized, which entailed compiling an extensive list of author names extracted from the university libraries of Kelaniya and Moratuwa. The dataset of author names (n=76,592 names) was obtained from the Tag 100 and Tag 700 data fields present within these libraries. To ensure data accuracy, a series of initial data cleaning steps were implemented to remove redundant, irrelevant, and incomplete entries from the dataset. It has been observed that libraries follow inconsistent patterns of name forms, without considering proper authority forms. Establishing a comprehensive automated author name authority file is essential to minimize confusion in these cases. Furthermore, adopting a proper transliteration process is important for effective authority control functions. To minimize errors in searching personal names, as identified by the survey, suitable name forms were automatically detected and separately compiled for authors. This compilation can help facilitate easier information searching across libraries.
