Open access scientific journals: an analysis of the DOAJ catalogue

Authors : Suênia Oliveira Mendes, Rosângela Schwarz Rodrigues


The research aims to analyse the publishers, countries of publication, citation indexes, article processing charges, and their inter-relations, in the journals that make up the Directory of Open Access Journals (DOAJ), a global directory that offers scientific information in immediate and exclusive open access.


Bibliographic, quantitative, and inferential study of 9,005 journals in the DOAJ, focusing on publishers, countries of publication, article processing charges, and citation indexes.


Calculation of absolute and relative frequencies, measurement of central tendency, chi-squared test, and Mann-Whitney U test using the R statistical software (version 3.2.4) with a 95% confidence interval.


Brazil is the country with the largest number of titles (10.9%), followed by the United Kingdom, which has a greater number of titles with article processing charges fees averaging US$ 1,474 for those that are DOAJ No Seal and US$ 862 for those that are certified DOAJ Seal. Europe has the greatest number of open access titles (47.6%).

The Hindawi Publishing Corporation, Elsevier, De Gruyter Open, BioMed Central, and Springer are the publishers with the greatest number of journals and a higher presence in citation indexes (Journal Citation Reports and SCImago Journal Rank). DOAJ Seal journals are correlated and more likely to have article processing charges fees.


In the consolidation of open access journals, commercial publishers and countries with a tradition of scientific publishing continue to gather the majority of journals. Thus, the oligopoly of commercial scientific publishers is maintained.

Researchers depend on consultation with previous work in their field, most of which is published in scientific journals. The open access movement has affected journals and articles, providing new alternatives for accessing scientific content, and the Directory of Open Access Journals (DOAJ) is the most specialized and multidisciplinary database of open access journals.

The main goal of this study is to analyze publications that include “DOAJ” in their keywords, to determine how researchers in the areas of Library and Information Science and Social Science are studying it.

The specific objectives are: a) to describe the characteristics of journals indexed in the Web of Science, DOAJ, or SCOPUS that have published articles with “DOAJ” as a keyword; b) to identify the institutional affiliations of the authors of those articles; and c) to classify the articles according to subject area.

We identified 39 articles from 29 journals. The countries with the largest numbers of journals are the United States and the United Kingdom (six journals each). Most of the journals were open access, of which universities were the biggest publishers.

The countries with the largest numbers of authors were India (12), and Italy and Russia (11 each), and the journal that published the most articles was the University of Nebraska’s Library Philosophy and Practice (four articles).

Most articles analyze the quality (65.5%), followed by the growth (25.6%), of the Open Access Movement. An analysis of the subject areas covered revealed significant gaps, as the economic, legal and technological aspects of DOAJ were not represented.

Open access publishers: The new players

Authors : Rosângela Schwarz Rodrigues, Ernest Abadal, Breno Kricheldorf Hermes de Araújo

The essential role of journals as registries of scientific activity in all areas of knowledge justifies concern about their ownership and type of access. The purpose of this research is to analyze the main characteristics of publishers with journals that have received the DOAJ Seal.

The specific objectives are a) to identify publishers and journals registered with the DOAJ Seal; b) to characterize those publishers; and c) to analyze their article processing fees.

The research method involved the use of the DOAJ database, the Seal option and the following indicators: publisher, title, country, number of articles, knowledge area, article processing charges in USD, time for publication in weeks, and year of indexing in DOAJ.

The results reveal a fast-rising oligopoly, dominated by Springer with 35% of the titles and PLOS with more than 20% of the articles.

We’ve identified three models of expansion: a) a few titles with hundreds of articles; b) a high number of titles with a mix of big and small journals; and c) a high number of titles with medium-size journals.

We identify a high number of titles without APCs (27%) in all areas while medicine was found to be the most expensive area.

Commercial publishers clearly exercise control over the scope of journals and the creation of new titles, according to the interests of their companies, which are not necessarily the same as those of the scientific community or of society in general.

Research Articles about Open Access Indexed by Scopus: A Content Analysis

Authors : Rosângela Schwarz Rodrigues, Vitor Taga, Mariana Faustino dos Passos

This study analyzes research articles about open access (OA) indexed by the Scopus database, published from 2001 to 2015, in order to: (a) propose a categorization scheme about OA; (b) categorize the scientific production about OA; and (c) identify research trends on OA through disciplines at international level over time.

The authors used descriptive statistical methods and deductive content analysis using an unconstrained matrix in 347 selected research articles. The most explored themes were found to be “overview, current state, and growth of OA” counting for 98 articles (28.2%), and “awareness, perceptions, and attitudes toward OA” for 75 articles (21.6%).

As a conclusion, this study reveals a continuous and growing research interest by the OA community in studies focused on case studies regarding the development or evolution of OA in relation to certain groups, institutions, regions, periods, and how different actors perceive and address the OA movement.
