The main objective of this bibliometric study is to examine the publications globally from the Journal of Information Science in the specific period of forty two years (1979-2020). It provides insights into research-based activities. The data was extracted from the Science Citation Index database, Web of Science. This analysis provides information about the document types, yearly published documents within 42 years, top productive authors, top productive institutions and countries, frequently used keywords, and greatly cited articles. These aspects also meet the objectives of the study and provide the major findings such as the majority of the publications are "articles" belong to the Department of Information Science from the UK. That is also a top productive country. The author "Oppenheim C." is on the first position with highest total publications (TP). The highly used keyword is "Information" and the article "Usage patterns of collaborative tagging systems" has the highest ranking in the citation. This bibliometric research will update the researchers about the writing trends, institutions, and the countries involved in research activities. [ABSTRACT FROM AUTHOR]

Our aim was to re-evaluate the h-index of neurosurgical units in the United Kingdom and Ireland because it was 5 years since it was last reported. Using the Web of Science database, we collated cumulative (1950–2020), 10-year (2011–2020), 5-year (2016–2020), and 3-year (2018–2020) data for neurosurgical units in the United Kingdom and Ireland. Data included h-index, number of publications, and average number of citations. In total, 37 neurosurgical units were found in the United Kingdom and Ireland, which we ranked according to h-index. Since last reviewed 5 years previously, some units had changed their position, whereas others had remained reasonably static. The top 5 units were the same for the 10-year h-index between 2015 and 2020. The 5-year h-index showed some variation in the top 5 compared with the 10-year h-index. We were also able to compare 2 other studies with similar methods but differing from ours. The h-index for neurosurgical units is the most reliable bibliometric, which shows the academic standing and correlates well with amount of research grant obtained and size of department. It is particularly useful when calculated for the most recent 10-year and 5-year periods. Neurosurgical units change their rankings over time and, therefore, it is important to update the tables periodically. We propose an online database with open access showing all h-index and bibliometric data for neurosurgical units in the United Kingdom and Ireland. This database could provide a live and dynamic report of the academic standings of those units and could be used for grant applications and reviews. [ABSTRACT FROM AUTHOR]
