The research aim for this study was to compare three citation resources with one another to identify the citation resource with the most representative South African scholarly environmental sciences citation coverage. This paper focuses on the results of the content verification process which measured amongst others the citation counts, multiple copies and inconsistencies encountered across the three citation resources ISI Web of Science, Scopus and Google Scholar.

The research, the first phase of a longitudinal study, used a comparative research design method with a purposive, non-probability sample. Data from the South African scholarly environmental sciences journals for the year range 2004-2008 (first phase) were extracted from the three citation resources and compared.

It became evident during the verification process that the citation resources retrieved varied results. The total citation counts indicated that ISI Web of Science (WOS) retrieved the most citation results, followed by Google Scholar (GS) and then Scopus. WOS performed the best with total coverage of the journal sample population and also retrieved the most unique items. The investigation into multiple copies indicated that WOS and Scopus retrieved no duplicates, while GS retrieved multiple copies. Scopus delivered the least inconsistencies regarding content verification and content quality compared to the other two citation resources. Additionally, GS also retrieved the most inconsistencies, with WOS retrieving more inconsistencies than Scopus. Examples of these inconsistencies include author spelling and sequence, volume and issue number.

The findings of the study contribute to the understanding of the completeness of citation results retrieved from different citation resources. In addition it will raise awareness amongst academics to check citations of their work.

The purpose of this paper is to identify how intervention research weighed in nonintervention research in the field of human resource development (HRD) by examining the number, citation frequency and use of experimental studies in HRD academic journals.

A total of 2,700 articles published between 1990 and 2014 from Advances in Developing Human Resources (ADHR), European Journal of Training and Development (EJTD), Human Resource Development International (HRDI) and Human Resource Development Quarterly (HRDQ) were reviewed and analyzed to identify 91 experimental studies in the field.

The total citation frequency of the 91 articles was 1,100 (14 from ADHR, 222 from EJTD, 56 from HRDI and 808 from HRDQ). The authors reviewed the 1,100 subsequent studies that cited 91 experimental research studies and coded them to identify the research methods that each article adopted and to determine whether the studies used the citation to make causal statements. As a result, the authors found 459 causal statements from 1,100 citations. In particular, they identified the citation frequency of the causal statements used in nonintervention research to examine how often nonintervention studies used causal statements from intervention studies.

The results of the citation frequency could be different according to the search engines and timeframes. Books, technical reports, non-English studies, non-academic articles and inaccessible articles were not considered in this study. Theoretically, this study aimed to illuminate the magnitude of HRD experimental research conducted over 25 years and to what extent it influenced non-experimental studies. In addition, this study emphasized the importance of using the causal statements from experimental research to improve empirical validation in other studies.

When HRD practitioners need to identify alternative interventions to replace previous ones or to justify the use of specific interventions, they could consider causal statements from empirical studies as valid evidence. Further, HRD practitioners might collaborate with researchers to receive more direct and relevant information from experimental research.

Significantly, this study provides an integrative review of experimental research conducted in the field of HRD in terms of the number, citation frequency and proportion of using experimental research. An additional contribution is that it summarizes the research methods used in HRD studies over 25 years.

The aim of this study is to compare the situation of internet resource citations in scientific articles of the journals of Shahid Beheshti University of Medical Sciences from 2005‐2009.

The research method is an analytical survey with webometrics and citation analysis. The internet was used as a tool for accessing articles. They are separately analyzed on the basis of journal name and publication year. The analysis is done using MATLAB and Excel software.

A total of 717 articles from seven journals during five years were reviewed. Of 13,448 citations extracted, 120 internet references were found. The final results indicated that the sum of web citations is less than 1 per cent of total citations and only 52 per cent of internet citations in studied journal articles are available. The average half‐life for the medical journals is estimated to be 1.02 years.

To increase the rate of URLs availability, publishers should oblige authors to utilize online archives such as WebCite to preserve expected information for all of the citations referred to in their articles.

This research would be valuable since it is the first that studies stability and persistence of URL domains of medical journals published in Shahid Beheshti University of Medical Sciences according to type of domain names and file extensions. Moreover, this is the first time that the half‐life for medical universities web citations is calculated.

To date, librarians have not produced a study comparing databases that are appropriate for political science research. This study compares the coverage, content, and retrieval methods for nine databases. The study uses sampling to evaluate search results for six topics, providing relevancy percentages for each database. The article also reviews the types of documents cited in these samples, and provides recommendations for matching each database to particular research needs.

The purpose of this paper is to gain knowledge about the status and characteristics of the current web citations in published articles by Iranian researchers in the Science Citation Index (SCI). Besides investigating the growth in the presence of web resources in publications, the paper examines the accessibility and decay of web resources. Furthermore, the author will examine the provided information by the URLs to determine whether the cited contents by the authors signify the same information as the URLs.

The author used the survey research method. Thus, all documents by Iranian chemistry researchers recorded in the SCI database during 2006‐2009 were identified and then transferred to an Excel base. After a one‐by‐one examination, 46,762 web citations were extracted from a total number of 10,333 documents and were then analyzed, with the aid of two research assistants, in two months time (November and December of 2010), as specified in the research objectives. The citations were categorized into nine groups based on the feedback from the URLs' entries in the Internet Explorer browser.

The results showed that 46,762 citations (20 percent) of the total 187,823 available citations in the articles included web citations. The proportion percentage of web citations increased from 9 percent in 2006 to 39 percent in 2009. The average number of web citations for every article is 4.52. The most widely cited top level domains in URLs include the.org and.edu with, respectively, 31 percent and 23 percent; and when compared to other domains they reveal a greater tendency for stability. The highest percentage of inactive URLs was found to be associated with the .gov top level domain. Ultimately, 40,954 web citations were rendered accessible, of which 79 percent allowed easy and long‐term access to the authors' information intended in URLs. The decay rate for citations reveals an annual 5.2 percent increase. Long‐time inaccessibility to the authors' same intended information was shown to be mostly from URLs that returned the 404 error and also the URLs that had gone through information update. An about eight year half‐life was estimated for Iran's chemistry publications, which is rather promising in comparison with other fields of study.

The paper offers a quantitative analysis of the state of web citations application among chemistry researchers in Iran and voices concerns related to web citations in the publications in this field. The results of this study may be useful for providers of web contents, authors and editors in the field of chemistry publications.

The purpose of this paper is to analyze citation behaviors of students in the LIS field among a variety of local universities in Tehran.

A total of 259 MA dissertations in Library and Information Science submitted to five universities in Tehran during 2003‐2008 are examined. These universities were selected based on their location and the authors' accessibility to their university libraries. Overall, five out of nine universities in Iran which have Masters Courses in Library and Information Science were selected for this study. The data were gathered using a checklist by the author, who personally attended in university libraries and counted all dissertation references.

The study shows that students' citation behaviors are in favor of books, and Farsi e‐sources are lesser used by LIS students than English e‐sources. The total number of book citations is far more than total number of other formats. While this study could be useful in library acquisition decisions, it could also inform in areas related to issues students face in finding suitable pieces of information.

This study would be useful for educational and acquisition purposes in university libraries, since it examines citation behavior of students through a specific discipline.

The study deals with MA Library and Information Science dissertations among all universities of Tehran that teach LIS masters courses.

Citations have been used as a common basis to measure the academic accomplishments of scientific books. However, traditional citation analysis ignored content mining and without consideration of citation equivalence, which may lead to the decline of evaluation reliability. Hence, this paper aims to integrate multi-level citation information to conduct multi-dimensional analysis.

In this paper, books’ academic impacts were measured by integrating multi-level citation resources, including books’ citation frequencies and citation-related contents. Specifically, firstly, books’ citation frequencies were counted as the frequency-level metric. Secondly, content-level metrics were detected from multi-dimensional citation contents based on finer-grained mining, including topic extraction on the metadata and citation classification on the citation contexts. Finally, differential metric weighting methods were compared with integrate the multi-level metrics and computing books’ academic impacts.

The experimental results indicate that the integration of multiple citation resources is necessary, as it can significantly improve the comprehensiveness of the evaluation results. Meanwhile, compared with the type differences of books, disciplinary differences need more attention when evaluating the academic impacts of books.

Academic impact assessment of books via integrating multi-level citation information can provide more detailed evaluation information and cover shortcomings of methods based on single citation data. Moreover, the method proposed in this paper is publication independent, which can be used to measure other publications besides books.

Chemical databases have had a significant impact on the way scientists search for and use information. The purpose of this paper is to spark informed discussion and fuel debate on the issue of citations to chemical databases.

A citation analysis to four major chemical databases was undertaken to examine resource coverage and impact in the scientific literature. Two commercial databases (SciFinder and Reaxys) and two public databases (PubChem and ChemSpider) were analyzed using the “Cited Reference Search” in the Science Citation Index Expanded from the Web of Science (WoS) database. Citations to these databases between 2000 and 2016 (inclusive) were evaluated by document types and publication growth curves. A review of the distribution trends of chemical databases in peer-reviewed articles was conducted through a citation count analysis by country, organization, journal and WoS category.

In total, 862 scholarly articles containing a citation to one or more of the four databases were identified as only steadily increasing since 2000. The study determined that authors at academic institutions worldwide reference chemical databases in high-impact journals from notable publishers and mainly in the field of chemistry.

The research is a first attempt to evaluate the practice of citation to major chemical databases in the scientific literature. This paper proposes that citing chemical databases gives merit and recognition to the resources as well as credibility and validity to the scholarly communication process and also further discusses recommendations for citing and referencing databases.

The aim of this article is to study a locally‐oriented and book‐based research field using two Swedish language sources. Knowledge about citation patterns outside journal‐based, English language databases is scarce; thus a substantial part of research in the humanities and the social sciences is neglected in bibliometric studies.

Citation characteristics (publication type, language, gender and age) in the journal Tidskrift för Litteraturvetenskap (2000‐2009) and in grant applications (2006‐2009) are studied. The datasets are analyzed further, adopting an author‐co‐citation approach for depicting and comparing the “intellectual base” of the field.

It is shown that monographs and anthologies are the main publication channel in Swedish literary research. English, followed by Swedish, is the major language, and the gender of authors seems to influence citation practices. Furthermore, a common intellectual base of literary studies that is independent of publication type and language could be identified.

Bibliometric analysis of fields within the humanities needs to go beyond established databases and materials. The extensive use of recent English language monographs in Swedish literary studies informs the acquisition policy of university libraries serving literature scholars.

Citation analysis of non‐English sources offers further knowledge about scholarly fields with a local and “rural” profile. The approach of using references in grant applications provides a novel and promising venue for bibliometric research.
