arXiv is an open-access repository of electronic preprints and postprints approved for posting after moderation, but not peer review. It consists of scientific papers in the fields of mathematics, physics, astronomy, electrical engineering, computer science, quantitative biology, statistics, mathematical finance and economics, which can be accessed online. In many fields of mathematics and physics, almost all scientific papers are self-archived on the arXiv repository before publication in a peer-reviewed journal. Some publishers also grant permission for authors to archive the peer-reviewed postprint. Begun on August 14, 1991, arXiv.org passed the half-million-article milestone on October 3, 2008, had hit a million by the end of 2014 and two million by the end of 2021. As of April 2021, the submission rate is about 16,000 articles per month.
In academic publishing, a preprint is a version of a scholarly or scientific paper that precedes formal peer review and publication in a peer-reviewed scholarly or scientific journal. The preprint may be available, often as a non-typeset version available free, before or after a paper is published in a journal.
CiteSeerX is a public search engine and digital library for scientific and academic papers, primarily in the fields of computer and information science.
Open access (OA) is a set of principles and a range of practices through which research outputs are distributed online, free of access charges or other barriers. Under some models of open access publishing, barriers to copying or reuse are also reduced or removed by applying an open license for copyright.
BioMed Central (BMC) is a United Kingdom-based, for-profit scientific open access publisher that produces over 250 scientific journals. All its journals are published online only. BioMed Central describes itself as the first and largest open access science publisher. It was founded in 2000 and has been owned by Springer, now Springer Nature, since 2008.
PubMed is a free search engine accessing primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintain the database as part of the Entrez system of information retrieval.
Chemical Abstracts Service (CAS) is a division of the American Chemical Society. It is a source of chemical information and is located in Columbus, Ohio, United States.
ScienceDirect is a website that provides access to a large bibliographic database of scientific and medical publications of the Dutch publisher Elsevier. It hosts over 18 million pieces of content from more than 4,000 academic journals and 30,000 e-books of this publisher. The access to the full-text requires subscription, while the bibliographic metadata is free to read. ScienceDirect is operated by Elsevier. It was launched in March 1997.
An article or piece is a written work published in a print or electronic medium, for the propagation of news, research results, academic analysis or debate.
PubMed Central (PMC) is a free digital repository that archives open access full-text scholarly articles that have been published in biomedical and life sciences journals. As one of the major research databases developed by the National Center for Biotechnology Information (NCBI), PubMed Central is more than a document repository. Submissions to PMC are indexed and formatted for enhanced metadata, medical ontology, and unique identifiers which enrich the XML structured data for each article. Content within PMC can be linked to other NCBI databases and accessed via Entrez search and retrieval systems, further enhancing the public's ability to discover, read and build upon its biomedical knowledge.
Grey literature is materials and research produced by organizations outside of the traditional commercial or academic publishing and distribution channels. Common grey literature publication types include reports, working papers, government documents, white papers and evaluations. Organizations that produce grey literature include government departments and agencies, civil society or non-governmental organizations, academic centres and departments, and private companies and consultants.
Europe PubMed Central is an open-access repository which contains millions of biomedical research works. It was known as UK PubMed Central until 1 November 2012.
The Community Research and Development Information Service (CORDIS) is the European Commission's primary public repository and portal to disseminate information on all European Union (EU) funded research projects and their results in the broadest sense.
Research data archiving is the long-term storage of scholarly research data, including the natural sciences, social sciences, and life sciences. The various academic journals have differing policies regarding how much of their data and methods researchers are required to store in a public archive, and what is actually archived varies widely between different disciplines. Similarly, the major grant-giving institutions have varying attitudes towards public archival of data. In general, the tradition of science has been for publications to contain sufficient information to allow fellow researchers to replicate and therefore test the research. In recent years this approach has become increasingly strained as research in some areas depends on large datasets which cannot easily be replicated independently.
The National Library of Economics is the world's largest research infrastructure for economic literature, online as well as offline. The ZBW is a member of the Leibniz Association and has been a foundation under public law since 2007. Several times the ZBW received the international LIBER Award for its innovative work in librarianship. The ZBW allows for access of millions of documents and research on economics, partnering with over 40 research institutions to create a connective Open Access portal and social web of research. Through its EconStor and EconBiz, researchers and students have accessed millions of datasets and thousands of articles. The ZBW also edits two journals: Wirtschaftsdienst and Intereconomics.
An open-access mandate is a policy adopted by a research institution, research funder, or government which requires or recommends researchers—usually university faculty or research staff and/or research grant recipients—to make their published, peer-reviewed journal articles and conference papers open access (1) by self-archiving their final, peer-reviewed drafts in a freely accessible institutional repository or disciplinary repository or (2) by publishing them in an open-access journal or both.
Data publishing is the act of releasing research data in published form for use by others. It is a practice consisting in preparing certain data or data set(s) for public use thus to make them available to everyone to use as they wish. This practice is an integral part of the open science movement. There is a large and multidisciplinary consensus on the benefits resulting from this practice.
ScienceOpen is a web-based platform, that hosts open access journals. It is freely accessible for readers, authors and publishers, and it generates its revenues via promotional services for publishers and authors' institutions. The organization is based in Berlin and has a technical office in Boston. It is a member of CrossRef, ORCID, the Open Access Scholarly Publishers Association, STM Association and the Directory of Open Access Journals. The company was designated as one of “10 to Watch” by research advisory firm Outsell in its report “Open Access 2015: Market Size, Share, Forecast, and Trends.”
In France, open access to scholarly communication is relatively robust and has strong public support. Revues.org, a digital platform for social science and humanities publications, launched in 1999. Hyper Articles en Ligne (HAL) began in 2001. The French National Center for Scientific Research participated in 2003 in the creation of the influential Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities. Publishers EDP Sciences and OpenEdition belong to the international Open Access Scholarly Publishers Association.
The idea and practise of providing free online access to journal articles began at least a decade before the term "open access" was formally coined. Computer scientists had been self-archiving in anonymous ftp archives since the 1970s and physicists had been self-archiving in arXiv since the 1990s. The Subversive Proposal to generalize the practice was posted in 1994.
