The purpose of this paper is to propose an approach for identifying landmark papers in the long run. These publications reach a very high level of citation impact and are able to remain on this level across many citing years. In recent years, several studies have been published which deal with the citation history of publications and try to identify landmark publications.

In contrast to other studies published hitherto, this study is based on a broad data set with papers published between 1980 and 1990 for identifying the landmark papers. The authors analyzed the citation histories of about five million papers across 25 years.

The results of this study reveal that 1,013 papers (less than 0.02 percent) are “outstandingly cited” in the long run. The cluster analyses of the papers show that they received the high impact level very soon after publication and remained on this level over decades. Only a slight impact decline is visible over the years.

For practical reasons, approaches for identifying landmark papers should be as simple as possible. The approach proposed in this study is based on standard methods in bibliometrics.

This review aims to show, broadly, how the h‐index has become a subject of widespread debate, how it has spawned many variants and diverse applications since first introduced in 2005 and some of the issues in its use.

The review drew on a range of material published in 1990 or so sources published since 2005. From these sources, a number of themes were identified and discussed ranging from the h‐index's advantages to which citation database might be selected for its calculation.

The analysis shows how the h‐index has quickly established itself as a major subject of interest in the field of bibliometrics. Study of the index ranges from its mathematical underpinning to a range of variants perceived to address the indexes' shortcomings. The review illustrates how widely the index has been applied but also how care must be taken in its application.

The use of bibliometric indicators to measure research performance continues, with the h‐index as its latest addition. The use of the h‐index, its variants and many applications to which it has been put are still at the exploratory stage. The review shows the breadth and diversity of this research and the need to verify the veracity of the h‐index by more studies.

This paper aims to study the intellectual landscape of green purchase (GP) literature, visualize and analyse the temporal evolution, thematic mapping of emerging and future research themes using a systematic and quantitative literature review approach.

The study employs a bibliometric analysis and examines the bibliometric metadata consisting of 440 studies extracted from the Scopus database for the years 1990–2022 within the GP field.

The findings based on performance analysis and visualization networks reveal the productivity trend of GP by years, authors, academic relationships, international collaborations, top cited publications, most occurring keywords, existing and emerging themes and temporal theme evolution.

It provides a broader/macro view of the topic and lacks specificity and deeper analysis, which can be addressed in future bibliometric studies.

The integration of topics contributes to the development of the intellectual landscape of the GP research field and suggests thrust areas for future research. The study offers important implications for the academic community to gain a comprehensive and global understanding of green purchasing.

This research is unique as previous studies have not quantitatively compiled and extensively analysed work of these characteristics on the area under study using bibliometrics.

At first hearing the word ‘standardization’ has a certain uncomfortable, authoritarian ring about it. The phrase ‘international standardization’ may suggest a sort of levelling of all national and regional distinctions and the removal of most of the colourful things of life. And ‘international bibliographical standardization’ represents to many an unwarranted attempt to control the presentation of the fruits of their personal intellectual toil, and even, by implication, the contents also. Yet without standardization, in its various forms, we should lack safety at sea and such safety on land or in the air as the internal combustion engine allows us, we should never know the time or the temperature, we should not know in which direction we were going, nor could we measure how far we had gone. At home we could neither use our electrical appliances in a different area from that in which they were bought, nor replace an electric light bulb without first tinkering with it. Every individual part of every machine would have to be specially made by hand (though we have admittedly lost here in the disappearance of craftsmanship much of what we have gained in convenience). Sizes of shoes and other articles of clothing would be even more variable than they arc. In the intellectual sphere we have but to cite the outstandingly successful standardization of mathematical and musical notation.

This study aims to measure the research landscape of the solar energy literature published in India during the years 1989–2022, indexed in the Web of Science (WoS) database. The study examines the performance analysis and social network analysis of the literature.

The literature on solar energy published in India and indexed in the WoS between 1989 and 2022 was retrieved using a string of 13 related and synonymous terms as per the Dewey Decimal Classification Scheme and Sears list of Subject Headings. Excluding all other document types, a total of 16,623 journal articles were retrieved. Quantitative and visualization techniques were applied to analyze the data. VOSViewer was used to map the collaborative patterns among different entities.

India has published 16,623 journal articles over 33 years, spanning from 1989 to 2022, with an average annual growth rate of 19.64 and a compound annual growth rate of 16.06. The Department of Science and Technology emerges as the prominent funding agency, while Indian Institute of Delhi (IIT Delhi) is the most productive institute. More than 125 countries collaborate with India in the field, with the USA being the topmost collaborator. Prof. Bhim Singh from IIT Delhi is the most prolific author, while Solar Energy published from the United Kingdom by Elsevier is the most preferred journal.

The study is limited to the WoS’s Core Collection database. Hence, the results cannot be generalized across other databases.

The results of the study will be of extreme importance to the Indian scientific community, policymakers and policy planners, as it may help them in the reorientation of future research directions and the judicious allocation of resources.

The study demonstrates the essentiality of the field by tracking the research progress in the field over time and the importance of collaboration. The study is a valuable tool for identifying trends and assessing the impact of the research.

The National Central Library and later the National Lending Library for Science and Technology had always, as part of their services, provided libraries with locations or passed requests to possible sources when the items required were not in the stocks of these two institutions. These practices continued when the two libraries were amalgamated to form the Lending Division of the British Library in 1973; but it was known that several major libraries were not represented in the union catalogues and played little or no part in interlending, yet had resources which could supply many items that could not be obtained from other sources identified through union catalogues or by speculation. It was also known that several small, privately funded libraries with unique stocks, which had for many years co‐operated in the interlending system, were finding it increasingly difficult to justify a virtually free service to libraries at large whilst charging their own members for loans.

BOOKS are among the greatest and most wonderful achievements of human genius, they are also a powerful means of struggle for progress. The book accompanies man all his life; it is a creation of his brain and soul. It reflects the life of mankind and is the result of collective efforts of author and publisher, type‐setter and illustrator. But foremost a book is always and everywhere a social and political phenomenon. One of the most apt evaluations of the book was given by V. I. Lenin in 1917, when he was known to state to A. V. Lunacharsky, “The book is a great force indeed”.

By Theodore Besterman's death on 10 November 1976 in his seventy‐first year, scholarship, bibliography and documentation and a wide range of esoteric subjects have lost a master of near fabulous achievement—how else, to note only two of his works, can one describe the 107 volumes of Voltaire's correspondence which he completed in twelve years as virtually a one‐man job, except for the help of an assistant for part of the time provided by the Swiss Foundation for Scientific Research, and the three editions of the World bibliography of bibliographies. To these great solo achievements as a scholar must be added his skill and discrimination as a collector, outstandingly of Voltaire editions and manuscripts and every Voltaire relic which he could procure as the material basis of the publications and activities of the Institut et Museé Voltaire in Geneva which was established solely through Besterman's creative efforts.

The main purpose of this paper is to measure the scholarly impact of LIS (Library and Information Science) open access journals (OA journals), most of which are not indexed by the Web of Science (WoS). In addition, the paper seeks to discuss measurement methods beyond citation analysis.

The study selected 97 LIS OA journals as a sample and measured their scholarly impact on the basis of citations and links. The citation counts in WoS, coverage in LISA, Web links, WIFs and Page Rank of the journals are retrieved and calculated, and correlations between citation counts, links, pages, WIFs, and Page Rank are also analyzed.

The results indicate that LIS OA journals have become a significant component of the scholarly communication system. The Journal of the Medical Library Association enjoys the highest citation counts in WoS. This journal, together with D‐Lib Magazine, Information Research, Ariadne, Cybermetrics, and First Monday are the six most important LIS OA journals. With regard to coverage in LISA, Bulletin des Bibliothèques de France (2151) performs best. As a whole, the Page Rank is relatively high, mostly at 6, 7, or 8. The study finds that correlation between citation‐based measurements and link‐based measurements tends to be significant.

This paper uses the web as a global resource to measure the impact of LIS OA journals by analyzing citation, coverage, web links and Page Rank. The focus of this study is the value of the web as a source of impact indices, rather different from the traditional research methods. It contributes to the scholarly impact measurements of OA journals.

This study aims to identify research trends and technological evolution in the polymer three-dimensional (3D) printing process that can effectively identify the direction of technological advancement and progress of acceptance in both society and key manufacturing industries.

The Scopus database was used to collect data on polymer 3D printing papers. This study uses bibliometric approach along with network analytic techniques to identify and discuss the most important countries and their scientific collaboration, compares income groups and analyses keyword trends.

It was found that top research production results from heavy investments in research and development. The USA has the highest number of papers among the high-income countries. However, scientific production in the other two income groups is strongly dominated by China and India. Keyword analysis shows that countries with lower incomes in certain areas, such as composite and bioprinting, have fallen behind other groups over time. International collaborations were suggested as mechanisms for those countries to catch up with the current research trends. The evolution of the research field, which started with a focus on 3D printing processes and shifted to printed part designs and their applications, was discussed. The advancement of the research topic suggests that translational research on polymer 3D printing has been led mainly by research production from higher-income countries and countries with large research and development investments.

Previous studies have conducted performance analysis, science mapping and network analysis in the field of 3D printing, but none have focused on global research trends classified by country income. This study has conducted a bibliometric analysis and compared the outputs according to various income levels according to the World Bank classification.
