Purpose – The purpose of this paper is to highlight the retrieval effectiveness of search engines taking into consideration both precision and relative recall. Design/methodology/approach – The study is based on search engines that are selected on the basis of Alexa (Actionable Analytics for the web) Rank. Alexa listed top 500 sites, namely, search engines, portals, directories, social networking sites, networking tools, etc. But the scope of study is confined to only general search engines on the basis of language which was confined to English. Therefore only two general search engines are selected for the study . Alexa reports Google.com as the most visited website worldwide and Yahoo.com as the fourth most visited website globally. A total of 15 queries were selected randomly from PG students of Department of Library and Information Science during a period of eight days (from May 8 to May 15, 2014) which are classified manually into navigational, informational and transactional queries. However, queries are largely distributed on the two selected search engines to check their retrieval effectiveness as a training data set in order to define some characteristics of each type. Each query was submitted to the selected search engines which retrieved a large number of results but only the first 30 results were evaluated to limit the study in view of the fact that most of the users usually look up under the first hits of a query. Findings – The study estimated the precision and relative recall of Google and Yahoo. Queries using concepts in the field of Library and Information Science were tested and were divided into navigational queries, informational queries and transactional queries. Results of the study showed that the mean precision of Google was high with (1.10) followed by Yahoo with (0.88). While as, mean relative recall of Google was high with (0.68) followed by Yahoo with (0.31), respectively. Research limitations/implications – The study highlights the retrieval effectiveness of only two search engines. Originality/value – The research work is authentic and does not contain any plagiarized work.

Purpose Bibliometrics is one of the research fields in library and information science that deals with the analysis of academic entities. In this regard, to gauge the productivity and popularity of authors, publication counts and citation counts are common bibliometric measures. Similarly, the significance of a journal is measured using another bibliometric measure, impact factor. However, scarce attention has been paid to find the impact and productivity of conferences using these bibliometric measures. Moreover, the application of the existing techniques rarely finds the impact of conferences in a distinctive manner. The purpose of this paper is to propose and compare the DS-index with existing bibliometric indices, such as h-index, g-index and R-index, to study and rank conferences distinctively based on their significance. Design/methodology/approach The DS-index is applied to the self-developed large DBLP data set having publication data over 50 years covering more than 10,000 conferences. Findings The empirical results of the proposed index are compared with the existing indices using the standard performance evaluation measures. The results confirm that the DS-index performs better than other indices in ranking the conferences in a distinctive manner. Originality/value Scarce attention is paid to rank conferences in distinctive manner using bibliometric measures. In addition, exploiting the DS-index to assign unique ranks to the different conferences makes this research work novel.

Purpose – The purpose of this study was to examine whether the logical structure of abstracts in the areas of materials science and technology and library and information science comply with the ISO 214 or IMRAD formats, while also suggesting guidelines for components of abstracts. Design/methodology/approach – In the first part of the research the components of abstracts are analysed. The results showed that not all the proposed structural elements are present in the abstracts. Therefore also the improved prototypes and recommended abstracts are developed to examine the satisfaction of readers with different forms of abstracts. According to the results of satisfaction of readers with different forms of abstracts, uniform guidelines for the components of abstracts in accordance with the IMRAD format are proposed. Findings – The introduction (I) should include three sentences of background information. The method (M) should include three sentences of method. The results (R) should include three sentences of results. The discussion (D) should include two sentences of conclusions. The conclusions should present the implications of the results on subjects that were not part of the study, suggestions for possible application of the findings, suggestions for further research work and an evaluation of the research. Originality/value – It is important to emphasize that even if the guidelines for writing abstracts by the individual journal exist, authors do not always take them into account. Therefore, it is important that the abstracts that are actually published in journals were analysed. It is also important that the opinion of researchers was taken into account.

Purpose The purpose of this paper is to compare four popular academic social networking sites (ASNSs), namely, ResearchGate, Academia.edu, Mendeley and Zotero. Design/methodology/approach Evaluation method has been used with the help of checklist covering various features of ASNSs. A structured checklist has been prepared to compare four popular ASNSs, comprising 198 dichotomous questions divided into 12 broad categories. Findings The study found that performance of ASNSs using the latest features and services is not up to the mark, and none of the site is rated as “Excellent”. The sites lack in incorporation of session filters; output features; privacy settings and text display; and search and browsing fields. Availability of bibilographic features and general features is poor in these sites. Further, altmetrics and analytics features are not incorporated properly. User interface of the sites need to improve to draw researchers to use them. The study report reveals that ResearchGate scored the highest, 61.1 per cent points, and was ranked “above average”, followed by Academia.edu with 48.0 per cent and Mendeley with 43.9 per cent are ranked “average”. However, the Zotero (38.9 per cent) was ranked “below average”. Practical implications Accreditation agencies can identify suitable sites in the evaluation of institutions’ research output. Further, students and faculty members can choose the site suiting their needs. Library and information science professionals can use the checklist to impart training to the academic community which can help fostering research and development activities. Originality/value The study identifies features that ought to be available in a model ASNS. These features are categorized into 12 broad categories. The findings can also be used by developers of the sites to enhance functionalities. Institutions can choose suitable sites while collaborating with other institutions.

Purpose The purpose of this study is to provide a bibliometric analysis of knowledge management (KM) literature published in the field of library and information science. KM is a systematic process of acquisition, extraction, organization and dissemination of knowledge in any organization. This study will help identify trends, emerging concepts and innovations in this particular field. Design/methodology/approach The data set of the study consists of 6,088 published documents the authors obtained from the ISI Web of Science database during 1900 and 2017. The analysis of literature about the library and information science consisted of five categories including productive institutions, prolific authors, annual publications, citations and highly cited articles. The documents included in this study include research papers, conference papers, reviews, book reviews and editorials. Findings The study found that the USA leads the world regarding the number of research publications in the area of KM in the field of library and information science. Considering the publication period, 2007, 2012 and 2016-2017 are the most productive years regarding publications in this particular field; the number of citations has been increasing over the years. The study also found that Nanyang Polytechnic University is the most productive research institution and Blanca Martins from the Polytechnic University of Catalonia is the most prolific researcher in this specific field. Originality/value This study provides a detailed bibliometric analysis of KM literature published in the field of library and information science. This study is an excellent example for researchers who are interested in conducting bibliometric studies.

Purpose Neutrality is a much debated value in library and information science (LIS). The “neutrality debate” is characterised by opinionated discussions in contrasting contexts. The purpose of this paper is to fill a gap in the literature by bringing these conceptions together holistically, with potential to deepen understanding of LIS neutrality. Design/methodology/approach First, a literature review identified conceptions of neutrality reported in the LIS literature. Second, seven phenomenographic interviews with LIS professionals were conducted across three professional sectors. To maximise variation, each sector comprised at least one interview with a professional of five or fewer years’ experience and one with ten or more years’ experience. Third, conceptions from the literature and interviews were compared for similarities and disparities. Findings In four conceptions, each were found in the literature and interviews. In the literature, these were labelled: “favourable”, “tacit value”, “social institutions” and “value-laden profession”, whilst in interviews they were labelled: “core value”, “subservient”, “ambivalent”, and “hidden values”. The study’s main finding notes the “ambivalent” conception in interviews is not captured by a largely polarised literature, which oversimplifies neutrality’s complexity. To accommodate this complexity, it is suggested that future research should look to reconcile perceptions from either side of the “neutral non-neutral divide” through an inclusive normative framework. Originality/value This study’s value lies in its descriptive methodology, which brings LIS neutrality together in a holistic framework. This framework brings a contextual awareness to LIS neutrality lacking in previous research. This awareness has the potential to change the tone of the LIS neutrality debate.

Purpose – The purposes of this paper are to deal with the questions: because search engines, social networks and app-stores are often referred to as gatekeepers to diverse information access, what is the evidence to substantiate these gatekeeper concerns, and to what extent are existing regulatory solutions to control gatekeeper control suitable at all to address new diversity concerns? It will also map the different gatekeeper concerns about media diversity as evidenced in existing research before the background of network gatekeeping theory critically analyses some of the currently discussed regulatory approaches and develops the contours of a more user-centric approach towards approaching gatekeeper control and media diversity. Design/methodology/approach – This is a conceptual research work based on desk research into the relevant and communications science, economic and legal academic literature and the relevant laws and public policy documents. Based on the existing evidence as well as on applying the insights from network gatekeeping theory, this paper then critically reviews the existing legal/policy discourse and identifies elements for an alternative approach. Findings – This paper finds that when looking at search engines, social networks and app stores, many concerns about the influence of the new information intermediaries on media diversity have not so much their source in the control over critical resources or access to information, as the traditional gatekeepers do. Instead, the real bottleneck is access to the user, and the way the relationship between social network, search engine or app platforms and users is given form. Based on this observation, the paper concludes that regulatory initiatives in this area would need to pay more attention to the dynamic relationship between gatekeeper and gated. Research limitations/implications – Because this is a conceptual piece based on desk-research, meaning that our assumptions and conclusions have not been validated by own empirical research. Also, although the authors have conducted to their best knowledge the literature review as broad and as concise as possible, seeing the breadth of the issue and the diversity of research outlets, it cannot be excluded that we have overlooked one or the other publication. Practical implications – This paper makes a number of very concrete suggestions of how to approach potential challenges from the new information intermediaries to media diversity. Social implications – The societal implications of search engines, social networks and app stores for media diversity cannot be overestimated. And yet, it is the position of users, and their exposure to diverse information that is often neglected in the current dialogue. By drawing attention to the dynamic relationship between gatekeeper and gated, this paper highlights the importance of this relationship for diverse exposure to information. Originality/value – While there is currently much discussion about the possible challenges from search engines, social networks and app-stores for media diversity, a comprehensive overview in the scholarly literature on the evidence that actually exists is still lacking. And while most of the regulatory solutions still depart from a more pre-networked, static understanding of “gatekeeper”, we develop our analysis on the basis for a more dynamic approach that takes into account the fluid and interactive relationship between the roles of “gatekeepers” and “gated”. Seen from this perspective, the regulatory solutions discussed so far appear in a very different light.

Purpose The purpose of this paper is to challenge librarians to reconceptualize their professional self-image and practice so that it more closely aligns with the information science discipline that is part of the Masters of Library and Information Science degree. Design/methodology/approach This column is primarily theoretical and philosophical but also draws on the author’s observations of trends and patterns in both librarianship and changes in information needs in recent years. Findings Urgent, high-cost information needs created by COVID-19 and climate change coexist in a reality where technological change has made traditional librarian roles and functions less critical. By developing their information science skills and strengthening their professional identity as information scientists, librarians have the opportunity to address the urgent information needs of the day while remaining highly relevant professionals. Practical implications Librarians will need to strengthen their science-related skills and knowledge and begin to promote themselves as information scientists. Social implications Librarians are in a position to make a meaningful contribution to two of the most pressing challenges of the day, climate change and dealing with the COVID-19 pandemic. Originality/value This paper is relevant to all librarians at any stage of their career. It will help them to reflect on both their skillset and career path and to make any needed adjustments so that they can remain relevant in a volatile and demanding information environment.

PurposeThis article presents a secondary analysis of previously published data in order to drive discussion of the library profession’s current state of preparedness in working with patrons with disabilities.Design/methodology/approachThis article used a secondary analysis of survey data that have been previously published to determine what the continuum of data said about the current state of preparedness in the profession when working with people with disabilities.FindingsA comparison of the data from both surveys reveals that there are not only gaps in library graduate school education related to disability and accessibility but also that those gaps are not being addressed through professional development and staff training after students enter the workforce.Research limitations/implicationsThis was a secondary analysis of data, so no new data could be added. There was also no representation from library graduate school administration.Practical implicationsAn awareness is built that there needs to be more instruction for library graduate students and library employees on topics related to disability, accessibility and assistive technologies.Originality/valueThe topic has never been studied before in this kind of continuum of data, and the use of the secondary analysis of data with the library and information science profession is exceedingly rare.

Purpose This study aims to find out the average journal packing density (JPD) of Library and Information Science (LIS) research journals published across the world. The concept, JPD, means the average number of research articles published by a research journal in one volume. Accordingly, the undergoing study evaluates the average number of research articles published in each volume of each research journal published in the field of LIS at the global level. Some other key aspects evaluated include the number of LIS research journal publishing countries, average JPD of LIS research journals at the continental level, etc. Design/methodology/approach This study is purely based on secondary data retrieved from SCImago, which is SCOPUS data. Keeping in view the objectives of this study, the data about research articles published in all LIS research journals during the period 2015 through 2019 were retrieved to undertake the study. Findings From the data analysis, it emerged that 256 research journals duly indexed by SCOPUS are published in the field of LIS across 36 countries. In all 48,596 research articles were published from 2015 to 2019 in these research journals at an average of 44.71 research articles per journal per volume. More than 75% of LIS research journals are published from Germany, Spain, Netherlands, the USA and the UK. Research journals published from the USA have higher JPD of 53.09 research articles per journal per volume, which is 18.74% higher than the average global JPD of LIS research journals. 50% of LIS research journal publishing countries are from Europe and the majority 52.55% LIS research articles were published in European LIS research journals. The average JPD of LIS research journals published from North America is 51.73 research articles per journal per volume, which is the highest across continents. Research limitations/implications Standardization of JPD of research journals irrespective of the subject discipline they are published in is important for many reasons and the foremost being, such standardization helps in keeping at bay the predatory research journals, which normally float such packing density norms, with the sole aim to earn money in the shape of manuscript handling charges, thereby publishing a far greater number of research article in each issue of a journal than the average research articles published by a research journal. Originality/value Very few studies have been conducted around the concept JPD, especially by the authors of this particular study. This study has however been particularized to the LIS subject discipline, while the findings add to existing lot of study already undertaken, hence outcome can be generalized.

Purpose The purpose of this paper is to explore the influence of selected factors in journal citations. Various factors can affect citations distribution of journals. Among them, skewness of citations distribution, author self-citation, journal self-citation and recitations (RCs) have been studied. Design/methodology/approach The present study based on 16 systematically selected journals indexed in Scopus under the subject category “Library and Information Science.” The study was confined to original research and review articles that were published in the selected journals in the year 2011. The temporal citation window from 2011 to 2014 was taken for analysis. Tools like, Scopus author ID, ORCID and author profiles from Google Scholar were used to minimize the error due to homonyms, spelling variances and misspelling in authors’ names. Findings It is found that citations distribution in majority of the journals under the study is highly skewed and more likely to follow log-normal distribution. The nature of authorship in papers was found to have positive effect on citation counts. Self-citing data show that higher ranked journals have rather less direct impact on total citation counts than their lower counterpart. RCs are also found to be more in top-tier journals. Though the influence of self-citations and RCs were relatively less at individual level on total citations of journals but combined, they can play a dominant role and can affect total citation counts of journals at significant level. Research limitations/implications The present study is based on Scopus database only. Therefore, citation data can be affected by the inherent limitation of Scopus. Readers are encouraged to further the study by taking into account large sample and tracing citations from an array of citation indexes, such as Web of Science, Google citations, Indian Citation Index, etc. Originality/value This paper reinforces that the citations received by journals can be affected by the factors selected in this study. Therefore, the study provides better understanding of the role of these selected factors in journal citations.
