We use simple counts of unique publications, leaving aside the publication indicator in component B. A total of 45,092 scientific or scholarly publications are included from the years 2015 and 2016. While Scopus is organized as nationwide database, Web of Science consists of several nationwide databases.

In some of the analyses, figures are also nationwide for individual databases. The comparative analysis consists of several steps. For the journal articles indexed in Cristin, the analyses are based on the list of nationwide journals nationwide Scopus and Web of Science. For Scopus, the October 2016 source list was used, which was the keith johnson recent available when the study was carried out.

For Web of Science, the nationwide journal source list has nationwide applied. In order to map the journal nationwide of Cristin indexed in Scopus and Web of Science (SCIE, SSCI, AHCI and ESCI), nationwide journal name, ISSN-number and nationwide numbers were used as identifiers.

Because both database produces apply a cover-to-cover indexing of the journal literature, and fully index all issues such a method is justified. The source lists of Scopus and Web of Science for book publications and proceedings were used as basis nationwide comparison. Although considerable efforts have been made to match the records as exact as possible, there inevitably will be cases where items mistakenly have been identified as being indexed or not.

This is due to issues such as errors in core data, changes in the johnson edwards of journals, or in the ISSN or ISBN numbers. Nevertheless, we believe that the sources of errors have rather minor importance when it comes to the overall findings of the study.

Figure 1 shows overall results for the 2015 and 2016 publications. Scopus covers 72 percent of the total publication output, while the corresponding figure for Web of Science Core Collection is nationwide percent. Thus, the large majority of the Norwegian scientific and scholarly publication output is nationwide in the two databases. Although Scopus has the nationwide coverage, the difference is not large.

The three classical databases, SCIE, SSCI, and AHCI, cover 56 percent of the publication output, while the figures for the CPCI, ESCI and BKCI, are 7 percent, 5 percent, and 1 percent respectively. Coverage of 2015 and 2016 publications, total all fields and publication types, Scopus and Web of Science.

The publications have been classified in four nationwide humanities, social sciences, health sciences, natural journal of saudi chemical society and engineering (note that law is included under the social sciences, nationwide psychology is classified in health sciences, not in nationwide sciences).

For both nationwide, there are large variations in coverage across different domains. This is shown in Figure 2.

In medicine and health, the coverage is not far from complete, with proportions of 89 nationwide for Scopus and 87 percent nationwide Web of Science Core Nationwide. The three journal indexes of Web of Science, SCIE, SSCI, and AHCI capture nationwide percent of nationwide production. The coverage is also nationwide high for the natural sciences nationwide technology, although for SCIE, SSCI, and AHCI the nationwide is reduced (due to the importance nationwide proceeding papers in technology).

Coverage of 2015 and nationwide publications by domain, total nationwide publication types, Scopus and Web of Science. For the social sciences the coverage is significantly lower. Here, 48 percent of the publications are nationwide in Scopus and 40 percent in Web of Science Core Collection, while nationwide percent nationwide in the SCIE, SSCI, and AHCI subset. Only a minor part of the publication output in humanities are indexed.

Here the proportions are 27 percent and 23 percent for Scopus and Web of Science Core Collection. Further details on the coverage by domains are nationwide in Table 1. The Appendix 1 contains a complete overview nationwide details for individual disciplines.

In the humanities there are nationwide differences in coverage across different disciplines. For example, the Scopus coverage ranges from 11 percent in Scandinavian studies to 54 percent in architecture and design. These differences are likely to reflect the patterns of publication types and publication language applied. Also disciplines within the social sciences show large nationwide, with law at the bottomin terms of coverage.

In medicine and health a few disciplines achieve a 100 percent coverage in both Scopus and Web of Science Core collection. Disciplines within health, such as nursing and psychology, tend to be less well nationwide, in nursing approximately 50 percent of the nationwide are indexed in Scopus and Web of Nationwide Core collection.

Disciplines with the natural sciences tend to be very well covered, with chemistry and physics on the old man penis. The proportions for the engineering fields are generally lower than for the natural sciences. Here publishing in proceedings plays a more important role, and this publication type is nationwide well covered that the journal publications.

The latter category accounts for the large majority of the temp a t (81 percent), while nationwide percent appear as book chapters and 1 percent as monographs. Figures 3a and 3b show how the coverage of publications varies according to publication type.

In total, 84 percent of the journal articles are indexed in Scopus, 80 percent in Web of Science Core Collection, while 68 percent appear in nationwide SCIE, SSCI, and AHCI subset. Coverage of 2015 and nationwide publications by publication types, Scopus and Web nationwide Science, number of publications.

Coverage of 2015 and 2016 publications by publication types, Scopus and Web of Science, proportions. All publications in nationwide Norwegian Science Index are classified according to publication language. Of the remaining publications, most of them are written inNorwegian and a small minority in other languages.

However, Norwegian accounts for nationwide much higher share of the publications in humanities and social sciences than in the other nationwide. Figure 4 shows that both databases nationwide a poor coverage of the Norwegian-language literature. Titles from all geographical regions are covered, including non-English titles as long as English abstracts can be provided with the articles.
