The centenary of IFLA is approaching. IFLA’s Library History Special Interest Group has embarked on various projects to prepare for the event, including the compilation of an edited volume of scholarly chapters on IFLA’s history. This article originated as a background paper for members of the Library History Special Interest Group and others who may be contemplating conducting research on IFLA with a view to the centenary in 2027. An overview is given of published sources for the historiography of IFLA. These include publications about IFLA published by IFLA and its structures, and by other parties. IFLA’s own publications include guidelines and standards; policy statements; reports on the work of its professional units and strategic advisory committees; the IFLA Publications Series; and report series such as the IFLA World Reports and Trend Reports. Much of this material is published on IFLA’s websites, both current and archived. It provides valuable evidence of IFLA’s activities. In this article, the emphasis is on material about IFLA published by IFLA itself and by other parties. The literature about IFLA includes historical accounts published as articles, books, book chapters and theses. Many contain useful bibliographies. With a view to identifying topics and themes for the historiography of IFLA, the subject matter of some 294 items about IFLA published from 2000 to 2022 inclusive is analysed. Brief attention is paid to possible themes emerging from the literature that may be useful in developing research on IFLA.

This research explored the current state of the continuing professional development of Thai academic librarians and the roles of continuing professional development providers, employing a mixed-methods approach. An online questionnaire was completed by 243 Thai academic librarians and in-depth interviews were conducted with 20 library directors and deputy directors. The quantitative data was analysed using descriptive analysis, while the qualitative data was examined through thematic analysis. The research found that academic librarians recognized the importance of participating in continuing professional development activities and exhibited a preference for online continuing professional development, with ‘in-house’ providers and academic library networks assuming significant roles. The study recommends focusing on information technology skills and English proficiency. Concise and dynamic guidance is offered for academic libraries and continuing professional development providers to reshape continuing professional development activities to post-pandemic dynamics, based on academic librarians’ needs, and align their offerings with contemporary academic library challenges and trends, better suiting Thailand’s evolving educational context.

National library and information associations are in essence meta-memory organizations. Yet the efforts of associations to secure their own history and protect their corporate memory for the future, especially in terms of safeguarding their internal archives, appear patchy. The ideas of the French historian Pierre Nora are examined, particularly his concept of lieux de mémoire (“sites of memory”), alongside associated concepts of invented tradition and heritage, which can be seen to intersect with the memorializing proclivities of national associations. Evidence is presented from a modest 2008 study of the archival policies of national library and information associations worldwide, reported by IFLA’s Library History Section. It is important to revisit this study because little publicity was given to it at the time; also, it provides a context for a recent case study undertaken by the author of the archival practices of the UK’s Chartered Institute of Library and Information Professionals.
国家图书馆和信息协会本质上是元记忆组织。然而，这些协会在保护自身历史和未来企业记忆方面所做的努力，尤其是在保护内部档案方面所做的努力，似乎并不完善。本文研究了法国历史学家皮埃尔-诺拉（Pierre Nora）的思想，特别是他的 "记忆之所"（lieux de mémoire）概念，以及相关的发明传统和遗产概念，可以看出这些概念与国家协会的纪念倾向有交集。国际图书馆员协会和图书馆联合会（IFLA）图书馆历史部 2008 年对世界各国图书馆和 信息协会的档案政策进行了一项规模不大的研究。重温这项研究非常重要，因为当时对它的宣传很少；同时，它也为作者最近对英国图书馆与信息专业人员特许协会的档案实践进行的案例研究提供了背景。

This study investigates the impact of multimedia within academic information literacy in the higher education sector. It considers the recent information and communications technology boom, its effect on academic information literacy preferences, and how it has affected pedagogy. Finally, it discusses the current and future trends of the influence of multimedia on pedagogical instruction. A survey of higher education students in three countries – the UK, Kenya and India – was undertaken to understand the shift towards multimedia in libraries. The aim was to determine if behavioural attributes (academic or artistic, verbalisers or visualisers) and the university’s location impacted multimedia learning. The results of the study do not support the aptitude–treatment interaction theory. In the current context, different learners (academic or artistic) need different kinds of instruction to optimise their learning. However, the survey found that students’ nature did not influence their choice of method of instruction (verbal or video). It also revealed that the university’s location facilitated or hampered students’ learning capabilities.

This study measured the individual differences in the service quality of Bangladeshi university libraries by type of university, user and gender. A modified SERVQUAL (service quality) model was adopted for the academic library environment, which included 30 items under five dimensions with a 7-point Likert scale. The survey was conducted among 61 teachers, 50 researchers and 455 students from two public, two international and two private universities in Bangladesh. The individual differences in library service quality were calculated through an analysis of variance and independent sample t-test for the university, user and gender categories. The overall service quality was significantly different ( p < .001) among the users of the public ( M = 4.02), private ( M = 5.08) and international ( M = 5.10) university libraries, as well as between male ( M = 4.48) and female ( M = 5.01) users. Several statistical methods supported the sampling adequacy, reliability and validity of the adapted model, which could be used as a basis for further assessments of library service quality by different demographic groups, both locally and globally.

This is a case study chronicling the rise and fall of the newspaper library that serviced the Vancouver Sun and Vancouver Province daily newspapers in Canada during the late 20th and early 21st centuries. This article examines a specific case of the decline of a major metropolitan newspaper company, the subsequent closure of the library that served two newsrooms, and the dissolution of its collections. A narrative inquiry approach to oral history was used to gather stories from the individuals involved in the development of the newspaper library. Reflections on the value and persistence of the collections developed by newspaper libraries are offered.

The present study aims to analyse the research domains, gender gap, and labour market perspectives of doctoral research in LIS in India. Sodhganga, a digital repository of Indian thesis and dissertations, was used for extracting doctoral thesis information and Jarvelin & Vakkari classification system was used for categorising the doctoral research topics. A total of 808 doctoral dissertations awarded between 2016 and 2020 were analysed using IBM SPSS and Tableau. The study's findings revealed that the growth of doctoral research in LIS is on rising trends with 150 PhD awarded in LIS every year. Information seeking (33.8%), library and information service activities (30.7%), and scientific & professional communication (16.5%) were found to be the preferred research themes among doctoral students during the study period. Furthermore, it is revealed that there is a gender gap in the number of PhDs conferred, with more men than women receiving these degrees. LIS professionals with a doctorate have the highest employment rate, at 96.2%, and most are in government jobs. Besides, only 40 percent of doctoral candidates reported receiving an incentive after the doctoral degree.

This article provides an overview of the recorded history of information associations, focusing especially on the Association for Information Science and Technology. Discussions with the archivists of three other professional associations about their beginnings, services, and funding provide the framework. While there are firm legal guidelines for keeping association records, there are no firm guidelines that specifically describe how to archive association records for historical purposes. Association records—including correspondence, votes, and addresses that are not held in formal publications—can reveal how and when decisions were made. Making these records available in archives is invaluable to historians. The authors’ views and opinions are based on what they have learned during the last several years of the active engagement of the Association for Information Science and Technology’s History Committee (HC) and curator, and the hope is that this article will be useful for other associations as they curate their own archives.

This article investigates the knowledge of research data management and services among library professionals in selected East African libraries. A survey research design was employed, and data was collected using a structured questionnaire from 180 respondents representing four East African countries: Malawi, Mozambique, Zambia and Zimbabwe. The findings reveal that only 31.1% of the selected East African librarians agreed that their institutional libraries provided research data management services. The standard research data management services offered by their libraries included data publishing, sharing and reuse, while collaboration with academic programmes was identified as an essential approach for research data management skill development. The study highlights the need for librarians to acquire legal, policy and advisory skills and knowledge of institutional and extra-institutional resources and the research life cycle for effective research data management service delivery.
