The purpose of this paper is to show that the extent of journal coverage, size and retrospectivity are three of the most commonly advertised features of database content. However, these data by themselves rarely provide a good enough sense of the real breadth of database coverage.

Some easy‐to‐calculate measures can provide vital signs of database coverage, which in turn may trigger in‐depth analysis at the individual journal level. When similar vital signs are produced from comparable databases and database segments, as is done for Arts and Humanities (A&H) sources in Web of Science, Scopus, H.W. Wilson and CSA databases for this paper, the real dimensions of the source coverage can be much better understood.

The decision to almost double the number of A&H journals reinforces the concept of enhancing the breadth of source coverage, obviously at the expense of depth of coverage. It is like those “If it is Tuesday, it must be Belgium” tours, where the emphasis is on beating the other tours by advertising more comprehensive coverage of European countries by “virtue” of visiting more countries in a single afternoon.

For scientometric searches so called “known item” searches are made, and the more records that are missing from core journals, the more harm is done to the subjects of the search. In subject searches a few good finds may be fine, but in “known item” searches that is not good enough. Doubling the cited reference enhanced segment, and eliminating the gaps in, say, the 1975‐2009 segment would have been much smarter policy for Scopus.

The purpose of this paper is to provide insights on the improvement of academic impact and social attention of Chinese collaboration articles from the perspective of altmetrics.

The authors retrieved articles which are from the Chinese Academy of Sciences (CAS) and indexed by Nature Index as sampled articles. With the methods of distribution analysis, comparative analysis and correlation analysis, authors compare the coverage differences of altmetric sources for CAS Chinese articles and CAS international articles, and analyze the correlation between the collaborative information and the altmetric indicators.

Results show that the coverage of altmetric sources for CAS international articles is greater than that for CAS Chinese articles. Mendeley and Twitter cover a higher percentage of collaborative articles than other sources studied. Collaborative information, such as number of collaborating countries, number of collaborating institutions, and number of collaborating authors, show moderate or low correlation with altmetric indicator counts. Mendeley readership has a moderate correlation with altmetric indicators like tweets, news outlets and blog posts.

International scientific collaboration at different levels improves attention, academic impact and social impact of articles. International collaboration and altmetrics indicators supplement each other. The results of this study can help us better understand the relationship between altmetrics indicators of articles and collaborative information of articles. It is of great significance to evaluate the influence of Chinese articles, as well as help to improve the academic impact and social attention of Chinese collaboration articles.

To the best of authors’ knowledge, few studies focus on the use of altmetrics to assess publications produced through Chinese academic collaboration. This study is one of a few attempts that include the number of collaborating countries, number of collaborating institutions, and number of collaborating authors of scientific collaboration into the discussion of altmetric indicators and figured out the relationship among them.

The first purpose of the present study is to investigate the coverage of journal articles in Physics in various sources of altmetrics. Secondly, the study investigates the relationship between altmetrics and citations. Finally, the study also investigates whether the relationship between citations and altmetrics was stronger or weaker for those articles that had been mentioned at least once in the sources of altmetrics.

The journal articles in Physics having at least one author from an Indian Institution and published during 2014–2018 in sources of altmetrics have been investigated. Altmetric.com was used for collecting altmetrics data. Spearman’s rank correlation coefficient (ρ) has been used as the data found to be skewed.

The highest coverage was found on Twitter (22.68%), followed by Facebook (3.62%) and blogs (2.18%). The coverage in the rest of the sources was less than 1%. The average Twitter mentions for journal articles tweeted at least once was found to be 4 (3.99) and for Facebook mentions, it was found to be 1.48. Correlations between Twitter mentions–citations and Facebook mentions–citation were found to be statistically significant but low to weak positive.

The study concludes that due to the low coverage of journal articles, altmetrics should be used cautiously for research evaluation keeping in mind the disciplinary differences. The study also suggests that altmetrics can function as complementary to citation-based metrics.

The study is one of the first large scale altmetrics studies dealing with research in Physics. Also, Indian research has not been attended to in the altmetrics literature and the present study shall fill that void.

This chapter examines the framing of the Black Lives Matter (BLM) Movement in mainstream media. An analytic sample of 4,303 articles collected from the Dow Jones Factiva database reveals variation in depth, breadth, and intensity of BLM coverage in the following newspapers between 2012 and 2016: The St. Louis Post-Dispatch, The New York Times, The Washington Post, The Wall Street Journal, and Al Jazeera English. We review contemporary literature on racial inequality and employ Media Framing and Critical Race Theory to discuss the implications of our findings on public perceptions, future policy formation, and contemporary social protest worldwide.

The increasing availability of digital editions of journals, and/or the incorporation of the full‐text versions of their papers in the largest aggregator databases, have been the highlights in the coming of age of digital libraries from many perspectives, ranging from collection development to preservation, from ready reference services to creating digital carrels. Full‐text availability of research papers through several digital resources is not merely a great convenience for distributing knowledge, but also an indirect indicator of the acknowledgement of the popularity and importance of journals and other serial publications (such as conference proceedings) in many disciplines where such sources are the primary venues for scholarly and professional publishing. One of the purposes of the author's current research project was to find out how well three business databases reflect the popularity and familiarity of peer ranking and rating through 50 top rated marketing‐focused and marketing‐related periodicals in the full‐text coverage of those journals. This paper seeks to present some results.

The target journals were selected from the list of 50 marketing‐focused and marketing‐related journals ranked by nearly 630 faculty members from marketing departments of US and international universities in an outstanding large scale survey and research project by Hult et al. The presence and time‐span of coverage of 50 journals and conference proceedings was analysed in three of the largest (partially) full‐text business databases.

The research found that many highly rated and ranked journals in the sample were absent or very modestly present in the full‐text subset even in the largest and most widely licensed three business databases tested.

The research adds a new dimension to evaluating databases by the specific criteria of full text availability of journals and other serial publications.

The purpose of this paper is to highlight the main features of the components of Proquest's giga database package for LIS faculty and students of databases and software services. These allow complimentary access to hundreds of indexing/abstracting, directory and full‐text databases, to RefWorks, the most sophisticated reference management program, and to SUMMON, a powerful digital resource discovery program.

This phase of the research focused on evaluating the largest module of GEP which offers 41 databases with more than 200 million records (half of them full‐text documents), on the new ProQuest software platform. The paper presents the major content and software features of this module.

The single module, GEP‐41, is an important contribution to LIS education, providing free access to LIS faculty and librarians to so many databases covering the LIS and LIS‐related fields, including the new ProQuest Library and Information Science database with more than 1.2 million items. The other modules of GEP extend the coverage to databases appropriate to LIS faculty and students interested in various tracks of librarianship. This project certainly will benefit Proquest itself in the long run. From the perspective of the primary beneficiaries, the LIS professors and students, the rich infrastructure for this project offers unprecedented opportunities for a digital renaissance in every aspect of LIS education and research.

This service, highly relevant for LIS education worldwide, was released in late 2012, and research papers have not been published about it yet. The paper focuses on the measurable, quantitative traits of the largest component of the service.

Company information is of considerable importance to the business community, but finding the right information is not easy. There are many possible information sources in a variety of formats which are often difficult to identify and control. Accurate and current guides to information sources are important and a prototype hypertext guide to sources of company information has been developed to examine the feasibility of utilising this technology to overcome some of the limitations of paper‐based guides. COMPInfo has been developed using GUIDE software. The structure of the system and the way in which this attempts to fulfil the requirements of a good company information guide are discussed. The advantages and problems of the prototype are considered, along with areas in which further development of the structure would be beneficial. In spite of its limitations, COMPInfo indicates that hypertext technology could provide a viable solution to the problems of producing an effective guide to the complex field of company information.

The purpose of this paper, the fourth in a series, is to discuss the pros and cons of the h‐index in the Web of Science (WoS).

The paper looks at the content and software advantages and disadvantages of WoS from the perspective of calculating the h‐index as a single measure of published research output and influence at the individual researcher level.

The paper finds that there are notable similarities and differences between WoS and Scopus, and that any WoS edition has a unique and important feature. As opposed to other cited reference enhanced databases, WoS always includes all the cited references for every record created, irrespective of the publication year.

The paper provides insights into the advantages and disadvantages of WoS from the perspective of calculating the h‐index.

Purpose – To evaluate the efficiency consequences of the Medicare Part D program.

Methods – We develop and empirically calibrate a simple theoretical model to examine the static and the dynamic welfare effects of Medicare Part D.

Findings – We show that Medicare Part D can simultaneously reduce static deadweight loss from monopoly pricing of drugs and improve incentives for innovation. We estimate that even after excluding the insurance value of the program, the welfare gain of Medicare Part D roughly equals its social costs. The program generates $5.11 billion of annual static deadweight loss reduction and at least $3.0 billion of annual value from extra innovation.

Implications – Medicare Part D and other public prescription drug programs can be welfare-improving, even for risk-neutral and purely self-interested consumers. Furthermore, negotiation for lower branded drug prices may further increase the social return to the program.

Originality – This study demonstrates that pure efficiency motives, which do not even surface in the policy debate over Medicare Part D, can nearly justify the program on their own merits.
