Publication delay adjusted impact factor: The effect of publication delay of articles on journal impact factor

The journal impact factor (JIF) has been questioned considerably during its development in the past half-century because of its inconsistency with scholarly reputation evaluations of scientific journals. This paper proposes a publication delay adjusted impact factor (PDAIF) which takes publication delay into consideration to reduce the negative effect on the quality of the impact factor determination. Based on citation data collected from Journal Citation Reports and publication delay data extracted from the journals’ official websites, the PDAIFs for journals from business-related disciplines are calculated. The results show that PDAIF values are, on average, more than 50% higher than JIF results. Furthermore, journal ranking based on PDAIF shows very high consistency with reputation-based journal rankings. Moreover, based on a case study of journals published by ELSEVIER and INFORMS, we find that PDAIF will bring a greater impact factor increase for journals with longer publication delay because of reducing that negative influence. Finally, insightful and practical suggestions to shorten the publication delay are provided.     

A comparison of drug literature coverage by Index Medicus and Drug Literature Index

We compared Index Medicus and Drug Literature Index during a search concerning the toxicity of eight drugs used in treating tropical diseases. Indexes covering the years 1969, 1970, and 1971 were searched. Index Medicus produced 198 citations and Drug Literature Index 309. There were seventy citations that appeared in both indexes, a duplication of 16%. Highest percentage of duplication for any one drug was 38.9%. We concluded that Index Medicus and Drug Literature Index provide complementary coverage in the area of drug toxicity and that, therefore, both tools should be consulted in searches of this nature.

Selection of journals for Index Medicus: a historical review

From the inception of the first Index Medicus, published in 1879, to the present, the National Library of Medicine has been concerned with the quality of journals in the Index. The Library has, therefore, sought advice repeatedly on how best to maintain currency of the Index without sacrificing quality and subject matter balance.Responding to suggestions, the Library decided in June 1964 to base its selection of journals on recommendations made by a panel consisting primarily of extramural consultants widely regarded as specialists in the totality of biomedical literature. Beginning with its first meeting in September 1964, this panel has been fortified in its reviews by advice from subject matter specialists. The panel, by its own wishes, which bear the endorsement of the Board of Regents of the Library, will continue to rely heavily on such expert advice in future evaluations of journals.

A comparison of journal coverage in Psychological Abstracts and the primary health sciences indexes: implications for cooperative serials acquisition and retention

An overlap study was performed to identify important psychology journals that are also of interest to biomedical scientists and health care practitioners. The journal lists of Index Medicus, Hospital Literature Index, Cumulative Index to Nursing and Allied Health Literature, and International Nursing Index were compared with the journal list of Psychological Abstracts. A total of 357 Psychological Abstracts titles were also in one or more of the health sciences indexes. A core list of forty-five titles covered by all of the indexes is presented in the Appendix. Results of the study are discussed vis-à-vis cooperative serials acquisition and retention efforts.     

Microsoft Academic automatic document searches: Accuracy for journal articles and suitability for citation analysis

Microsoft Academic is a free academic search engine and citation index that is similar to Google Scholar but can be automatically queried. Its data is potentially useful for bibliometric analysis if it is possible to search effectively for individual journal articles. This article compares different methods to find journal articles in its index by searching for a combination of title, authors, publication year and journal name and uses the results for the widest published correlation analysis of Microsoft Academic citation counts for journal articles so far. Based on 126,312 articles from 323 Scopus subfields in 2012, the optimal strategy to find articles with DOIs is to search for them by title and filter out those with incorrect DOIs. This finds 90% of journal articles. For articles without DOIs, the optimal strategy is to search for them by title and then filter out matches with dissimilar metadata. This finds 89% of journal articles, with an additional 1% incorrect matches. The remaining articles seem to be mainly not indexed by Microsoft Academic or indexed with a different language version of their title. From the matches, Scopus citation counts and Microsoft Academic counts have an average Spearman correlation of 0.95, with the lowest for any single field being 0.63. Thus, Microsoft Academic citation counts are almost universally equivalent to Scopus citation counts for articles that are not recent but there are national biases in the results.     

A survey on the use of CrossCheck for detecting plagiarism in journal articles

The purpose of this survey was to investigate journal editors' use of CrossCheck, powered by iThenticate, to detect plagiarism, and their attitude to potential plagiarism once discovered. A 22‐question survey was sent to 3,305 recipients, primarily scholarly journal editors from Anglophone countries, and a reduced 10‐question version to 607 editors from non‐Anglophone countries. The response rate was 5.6%. 42% of all respondents had used CrossCheck in their work. The main findings are as follows: (1) the plagiarism detection tool and its similarity report are extremely useful and effective and can assist editors in screening documents suspected of plagiarism; (2) responses show the journal editors' attitude and level of tolerance towards different kinds of plagiarism in different disciplines; (3) the survey results underscore a clear consensus on editorial standards on plagiarism, but there were small variations between different disciplines and countries, as well as between Anglophone and non‐Anglophone. The study also suggests that further work is needed to establish a universal principle and practical approaches to prevent plagiarism and duplicate publication.

Issue assignment delay of early-view articles: Impact on subscribers through an aggregator database

Journal articles are often made available prior to assignment to an issue, using labels like “early view,” “advanced online publication,” “ahead of print,” “online first,” or “in press.” While making articles available before an issue can speed up the scholarly communications cycle, a negative effect can be observed when full text is delivered through aggregator databases like EBSCO, ProQuest, or Gale products. This study assessed issue assignment delays across 18 journals which have full text aggregated in EBSCO's CINAHL Ultimate. Results show that articles published first in an early-view state are only available in the aggregator after they have been assigned to an issue. Any database-specific full-text delays (“embargos”) are then calculated from issue date rather than online publication date, leading subscribers who access the journals via aggregators to experience extended delays ranging from months to years in length.     

Lay summaries of open access journal articles: engaging with the general public on medical research

This study investigates attitudes to ‘lay’ or ‘plain‐English’ summaries of open access (OA) journal articles in the context of engaging the public with medical research. It places lay summaries in the wider contexts of patients' information‐seeking behaviour and OA publishing activities. It reports the results of qualitative research involving two stakeholder groups: employees of organizations with a stake in communicating OA medical research to the public, and members of the public who have experience of accessing online medical research. It shows that patient access to the research literature is seen as one of a number of important sources of information that can help them manage their health conditions as ‘informed patients‘. However, accessing the literature was reported to be problematical, particularly because of paywalls, and there were also difficulties in using it, including language barriers. Lay summaries were seen to make a helpful contribution to improving patient access to information. There is, however, a clear need to gather more evidence about the costs and benefits of such an approach and also on the potential ways in which OA can create benefits for the general public.
