Google Scholar, a widely used academic search engine, plays a major role in finding free full-text versions of articles. But little is known about the sources of full-text files in Google Scholar. The aim of the study was to find out about the sources of full-text items and to look at subject differences in terms of number of versions, times cited, rate of open access availability and sources of full-text files. Three queries were created for each of 277 minor subject categories of Scopus. The queries were searched in Google Scholar and the first ten hits for each query were analyzed. Citations and patents were excluded from the results and the time frame was limited to 2004-2014. Results showed that 61.1 % of articles were accessible in full-text in Google Scholar; 80.8 % of full-text articles were publisher versions and 69.2 % of full-text articles were PDF. There was a significant difference between the means of times cited of full text items and non-full-text items. The highest rate of full text availability for articles belonged to life science (66.9 %). Publishers' websites were the main source of bibliographic information for non-full-text articles. For full-text articles, educational (edu, ac.xx etc.) and org domains were top two sources of full text files. ResearchGate was the top single website providing full-text files (10.5 % of full-text articles).
In information systems, data are processed in various stages, and at every stage value is added in order to make the data useful for end users. Experts from different fields can assist these value-adding processes in various ways. This article discusses a theoretical model for determination of value-added processes in information systems. In this model, vital elements of every information system, that is, its goals, users, services and data, form a three-dimensional space. Each of these dimensions and the possible processes to add value in each dimension are discussed.
Purpose
This paper aims to propose an integrating model for creating virtual libraries in Iranian universities of medical sciences.
Design/methodology/approach
This study was conducted with an analytic survey method. The statistical population comprised 66 Iranian universities of medical sciences, of which 59 libraries participated in the study. A researcher-made checklist was used for data collection. To ensure the accuracy of data, interviews and, in some cases, observations were also performed. Statistical estimates, including frequency, percentage, cumulative frequency and diagrams, were used for data analysis, and the system analysis method was used for modeling.
Findings
Results demonstrated that the library software programs of the studied universities of medical sciences do not have desirable interoperability capabilities. Only Azarsa program can exchange information with other systems. In terms of metadata and its standards, the studied libraries use programs with various standards, with MARC and Dublin Core standards being the most frequently used ones in the studied sample.
Originality/value
The model proposed here for integration is a hybrid model which can translate metadata standards and use the Z39.50 and OEI protocol to transfer data.
Scholarship of teaching and learning plays an important role in informing educational practices in every discipline. The aim of this study was to identify the trends of research on library and information science (LIS) education. A total of 1,986 articles on LIS education published from 1999 to 2018 were retrieved from bibliographic databases using topical and thesaurus-based queries. They were analyzed for their topics, methods, educational level and aspect, country, and outlet. The results showed that curriculum (what we teach) received more research attention than pedagogy (how we teach). Teaching organization of information (including cataloguing, classification, and metadata) was the most researched topic. Educational aspects of some sectors such as archives and record keeping and academic libraries have received more attention, while some other sectors such as school libraries have not been covered as widely. Survey was the most popular research method used in research articles. There were 134 articles covering LIS education in the United States, representing the greatest coverage by geographic region. While some topics such as serials librarianship and law were discussed in early 2000, in recent years topics such as political literacy, crisis management, privacy, digital humanities, and GLAM convergence have emerged in the literature.
New methods of judging the impact of academic articles now include alternative metrics, and the goal of this study was to provide an insight into the journals and papers with top Altmetric attention scores (AAS) in the field of journalism. Scopus and Dimensions were used as the primary data sources. Fifteen journalism journals were identified from Scopus, and papers from these journals with an Altmetric Attention Score of over 100 were collected from Dimensions as the study's sample, which comprised 87 papers. Most of the papers with high AAS were published after 2017, and five were published in 2022. The sample included a larger number of closed access articles (n = 50) than open access (n = 37), although analysis revealed that open access articles had higher median Tweets than closed access. Articles on journalism practice were more likely to receive attention from news outlets. None of the papers with high AAS are highly cited, which may be due to the limited time to accumulate citations. The journal with the highest impact factor (Digital Journalism) did not have the greatest number of papers with high AAS, but had far higher scores on Twitter engagement than the other journals. The results do not show any correlation between impact factors and citation metrics and social metrics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
