Associate professor in information sciences, ORCID 0000-0002-4000-807X Abstract Data papers have been defined as scholarly journal publications whose primary purpose is to describe research data. Our survey provides more insights about the environment of data papers, i.e. disciplines, publishers and business models, and about their structure, length, formats, metadata and licensing. Data papers are a product of the emerging ecosystem of data-driven open science. They contribute to the FAIR principles for research data management. However, the boundaries with other categories of academic publishing are partly blurred. Data papers are (can be) generated automatically and are potentially machinereadable.

International audiencePurpose– Print theses and dissertations have regularly been submitted together with complementary material, such as maps, tables, speech samples, photos or videos, in various formats and on different supports. In the digital environment of open repositories and open data, these research results could become a rich source of research results and data sets, for reuse and other exploitation. The paper aims to discuss these issues.Design/methodology/approach– After introducing electronic theses and dissertations (ETD) into the context of eScience, the paper investigates some aspects that impact the availability and openness of data sets and other supplemental files related to ETD (system architecture, metadata and data retrieval, legal aspects).Findings– These items are part of the so-called “small data” of eScience, with a wide range of contents and formats. Their heterogeneity and their link to ETD need specific approaches to data curation and management, with specific metadata and identifiers and with specific services, workflows and systems. One size may not fit for all but it seems appropriate to separate text and data files. Regarding copyright and licensing, data sets must be evaluated carefully but should not be processed and disseminated under the same conditions as the related PhD theses. Some examples are presented.Research limitations/implications– The paper concludes with recommendations for further investigation and development to foster open access to research results produced along with PhD theses.Originality/value– ETDs are an important part of the content of open repositories. Yet, their potential as a gateway to underlying research results has not really been explored so far

Purpose: The article investigates the impact of the open archive initiative on the document supply of grey literature. Approach: The article is based on a comparative survey of five major scientific and technical information centres: The British Library (UK), CISTI (Canada), INIST-CNRS (France), KISTI (SouthKorea) and TIB Hannover (Germany). Findings: All major document suppliers are more or less deeply involved in the open archive movement, and this involvement has an obvious impact on the policy of acquisition, archiving and supply of grey literature (dissertations, reports, conferences etc.). Originality: The article is a follow-up study of our survey published in 2006.

The study aims to investigate the relationships between consumption of e-journals distributed by Elsevier ScienceDirect platform, publication (articles) and impact (citations) in a sample of 13 French universities, from 2003 to 2009. It adopts a value perspective as it questions whether or not publication activity and impact are some kind of return led by consumption. A bibliometric approach was used to explore the relations between these three variables. The analysis developed indicators inspired by the mathematical h-Index technique. Results show that the relation between consumption, publication and citations depends on the discipline's profile, the intensity of research and the size of each institution. Moreover, although relations have been observed between the three variables, it is not possible to determine which variable comes first to explain the phenomena. The study concludes by showing strong correlations, which nevertheless do not lead to clear causal relations. The article provide practical implication for academic library managers who want to show the added value of their electronic e-journals collections can replicate the study approach. Also for policy makers who want to take into account e-journals usage as an informative tool to predict the importance of publication activity. Originality: The study is the first French contribution to e-journal value studies. Its originality consists in developing a value viewpoint that relies on a bibliometric approach.

Purpose:The article investigates the evolution of document supply of print serials. Approach: The study is based on data from INIST-CNRSdocument supply requests and access to electronic resourcesof 95 serials with JCR impact factors in pharmacology. Data were collected from 1992 to 2003. Findings: The results distinguish four groups of serials each with a different evolution of supply requests. Nevertheless, the overall decline from 1999 is a global phenomenon linked to growing access to online journals and there seems little likelihood of a slowdown for the next few years. Originality: This is the first of three articles on a longitudinal study over 12 years on different aspects of the relationship between document supply and impact factor (citations) in pharmacology, a scientific domain with a high use of scientific information.

Purpose The purpose of this paper is to provide empirical insight into the use of the term and concept of grey literature in recent scientific papers. Design/methodology/approach The author conducted a scientometric analysis with Scopus data on 1,606 papers mentioning grey (or gray) literature published in 2018. Additionally, the author analysed the evolution between 1999 and 2018, and performed a content analysis on a random subsample of 70 papers in open access. Findings The percentage of papers that mention grey literature is low (0.05%) but steadily rising. They are from over 100 countries and a long tail of institutions, covering, namely, medical and health sciences and related topics. The dominant document type is systematic reviews, defining grey literature generally thought of as “unpublished”, “not peer reviewed” and “not in databases” and meaning, most of the time, all kinds of reports and conference papers. A large variety of sources and options on how to retrieve grey literature is mentioned, including Google and Google Scholar, specialised digital libraries, relevant websites, handsearching in bibliographic references and contact with experts in the field. Research limitations/implications The study is limited to papers indexed in the Scopus database, mainly journals, written in English, with a bias in favour of medical and life sciences. Originality/value There is no recent study on the real usage of the term of grey literature in a large sample of academic papers.

Open access (OA) to scientific information is one of the major challenges and objectives of actual public research policy. The purpose of this paper is to assess the degree of openness of scientific articles on bioeconomy, as one of the emergent research fields at the crossroads of several disciplines and with high societal and industrial impact. Based on a Web of Science (WoS) corpus of 2489 articles published between 2015 and 2019, we calculated bibliometric indicators, explored the openness of each article and assessed the share of journals, countries and research areas of these articles. The results show a sharp increase and diversification of articles in the field of bioeconomy, with a beginning long tail distribution. 45.6% of the articles are freely available and the share of OA articles is steadily increasing, from 31% in 2015 to 52% in 2019. Gold is the most important variant of OA. Open access is low in the applied research areas of chemical, agricultural and environmental engineering but higher in the domains of energy and fuels, forestry and green and sustainable science and technology. The UK and the Netherlands have the highest rates of OA articles, followed by Spain and Germany. The funding rate of OA articles is higher than of non-OA articles. This is the first bibliometric study on open access to articles on bioeconomy. The results can be useful for the further development of OA editorial and funding criteria in the field of bioeconomy.
