From Collections to Connectivity: Students’ Perceptions and Awareness of Academic Library Resources, Services, Systems, and Facilities at a Sri Lankan University
(University Librarians Association of Sri Lanka, 2026) Perera, W.P.G.L.; Johoran, S. Shabnam; Ayomi, P.M.; Adhikari, H.I.S.M.
This study was conducted as part of ongoing efforts to enhance service quality at a state university in Sri Lanka, focusing on students’ perceptions of the library’s services and resources. Understanding users’ perspectives is essential to ensure that library services align with users’ academic and informational needs. The study was conducted under the purview of the Library Quality Assurance Cell (LibQAC), with a specific focus on user services and feedback. The research employed a random sampling method, targeting both undergraduate and postgraduate students. Data were collected through self-administered questionnaires distributed via Google Forms, and the analysis was conducted using SPSS and Microsoft Excel. The survey examined five key areas: perceptions of the library information management system, electronic resources, physical and digital collections, library training programmes, and infrastructure facilities. Findings identified that students generally held a favourable view of the library’s services and infrastructure. The library information management system and electronic resources, such as e-books and e-journals, were well received. However, awareness of the Institutional Repository and the International Monetary Fund collection was notably low. Similarly, students were satisfied with the physical collections and staff support, except for resources for visually impaired students, which require further development. The study also highlighted a need for improved promotional strategies for library training programmes and digital services, particularly the library website. The results underscore the importance of continuous user engagement, awareness initiatives, and system enhancements to ensure inclusive, accessible, and effective library services. The study provides actionable insights for library administrators seeking to strengthen the alignment of services with user expectations in a rapidly evolving academic environment.
Leveraging Google Analytics to Enhance User Engagement: A Case Study of a State University Library Website in Sri Lanka
(University Librarians Association of Sri Lanka, 2026) Senanayake, S.G.N.C.; Liyanage, R.D.; Ramanan, T.
This study aimed to examine the effectiveness of a university library website using Google Analytics, which tracks and analyses website traffic and user behaviour to inform performance optimisation. With the Global Site Tag integration, data were collected over a twenty-four-month period from July 2022 to July 2024. Descriptive statistics and correlation analysis were employed to examine user behaviour patterns, traffic sources, and engagement metrics. The analysis revealed approximately 46,000 users, of whom approximately 44,000 (94.9%) were new users, indicating that a high proportion of visitors were first-time users. Engagement metrics included an engagement rate of 61.06% and an average engagement time of 1 minute and 53 seconds. The website also recorded a bounce rate of 42.7%, which warrants consideration alongside other engagement indicators. Correlation analysis identified significant relationships between selected variables. A moderate positive correlation was reported between device category and average engagement time (r = .560, p = .002), while strong positive correlations were observed between new users and sessions (r = .925, p < .001), event count and average engagement time (r = .780, p < .001), and engaged sessions and average engagement time (r = .926, p < .001). The findings indicate that device type, user interactions, and session characteristics were significantly associated with website engagement. The recommendations include (i) mobile optimisation for the substantial mobile user base, (ii) enhanced search engine optimisation strategies to increase organic traffic, (iii) website redesign with improved navigation, (iv) targeted marketing initiatives, and (v) continuous performance monitoring through Google Analytics. Overall, the study demonstrates the value of web analytics in informing data-driven decisions to enhance digital library service effectiveness.
Evaluating outreach engagement practices of public libraries in the Kalutara District, Sri Lanka, with special reference to the United Nations’ Sustainable Development Goals (SDGs)
(University Librarians Association of Sri Lanka, 2026) Perera, K.K.N.L.; Gamage, C.K.
This paper discusses the outreach and engagement activities conducted by officers in charge of public libraries (PLs) in the Kalutara District of Sri Lanka and their alignment with the United Nations (UN) Sustainable Development Goals (SDGs). The main objective was to identify and analyse the outreach activities conducted by officers in charge of PLs in the Kalutara District. The study also examined the associations between the level of outreach activities and the designation categories and educational qualifications of the officers in charge of these PLs. A structured questionnaire was used as the data collection tool. The entire population of PLs (N = 64) was included in the study, and the response rate was 67% (n = 43). Both thematic and statistical analyses were used. Six themes of outreach activities emerged: (i) Reading Promotion and Literacy Engagement, (ii) Health Awareness and Wellbeing Outreach, (iii) Skill Development and Livelihood Support, (iv) Mobile Library and Inclusive Community Services, (v) Cultural and Community Engagement Programs, and (vi) Environmental Awareness Initiatives. These themes aligned with activities and the educational qualifications of the officers in charge of PLs (χZ = 0.88, SDGs 3, 4, 5, 8, 10, 11, 13, and 15. No significant association was found between the level of outreach activities and the designations of the officers in charge of PLs (χZ = 3.77, p = .583). Moreover, no significant association was found between the level of outreach p = .927). It is recommended that outreach activities be integrated into a structured framework aligned with the SDGs, supported by capacity-building programmes, targeted training sessions, short courses, impact-assessment initiatives, monitoring indicators, institutional support mechanisms, sustainable funding pathways, and stronger community partnerships to standardise community outreach activities in the study sample.
External ophthalmomyiasis by larvae of Oestrus ovis (sheep nasal botfly): Second case report from Sri Lanka
(University of Colombo, 2022) Gunathilake, J.A.M.T.N.; Gunawardena, S; Dayawansa, K.R.; Senanayake, S.A.S.C.; Gunatilake, M.H.; Rajapaksha, G.
Introduction: External ophthalmomyiasis is the invasion of superficial tissues of the eye by fly larvae of the order Diptera. Human ophthalmomyiasis due to Oestrus ovis has been reported worldwide, typically in farmers and shepherds, especially in sheep and goat rearing countries of the Mediterranean basin. It is rare in Sri Lanka, and this is the second case that is being reported. In 2004, the first case was identified in a paddy farmer residing in Puttalam.
Serodiagnosis of Leishmania donovani induced cutaneous leishmaniasis: A method comparison study
(University of Colombo, 2022) Samarakone, A.S.C.; Siriwardana, H.V.Y.D.; Soysa, P.; Ali, N.; Bhattacharyya, A.; Ejazi, S.A.; Deepachandi, B,
Introduction: Sri Lanka reports a large focus of cutaneous leishmaniasis (CL). CL is not known to exert a high humoral response. However, we detected a high seroprevalence for CL in Sri Lanka and developed a cost-effective in-house ELISA assay that has been described previously. This assay is important to detect microscopy negative patients prior to conducting second line investigations and to detect pre-clinical infections in the field. The aim of the current study was to compare the local assay with other known assays. Methods: Study samples (n=100) were collected randomly from patients with laboratory confirmed CL. Control samples (n=25) were collected through field visits to disease endemic and non-endemic areas. In-house ELISA, DAT, Indian dipstick test and rK39 strip test were carried out on all study samples. The specificity and sensitivity were analysed. The cost analysis was also done per patient.
