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.
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.
A citation index is a kind of bibliographic index, an index of citations between publications, allowing the user to easily establish which later documents cite which earlier documents. A form of citation index is first found in 12th-century Hebrew religious literature. Legal citation indexes are found in the 18th century and were made popular by citators such as Shepard's Citations (1873). In 1961, Eugene Garfield's Institute for Scientific Information (ISI) introduced the first citation index for papers published in academic journals, first the Science Citation Index (SCI), and later the Social Sciences Citation Index (SSCI) and the Arts and Humanities Citation Index (AHCI). American Chemical Society converted its printed Chemical Abstract Service into internet-accessible SciFinder in 2008. The first automated citation indexing was done by CiteSeer in 1997 and was patented. Other sources for such data include Google Scholar, Microsoft Academic, Elsevier's Scopus, and the National Institutes of Health's iCite.
Google Scholar is a freely accessible web search engine that indexes the full text or metadata of scholarly literature across an array of publishing formats and disciplines. Released in beta in November 2004, the Google Scholar index includes peer-reviewed online academic journals and books, conference papers, theses and dissertations, preprints, abstracts, technical reports, and other scholarly literature, including court opinions and patents.
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.
A postprint is a digital draft of a research journal article after it has been peer reviewed and accepted for publication, but before it has been typeset and formatted by the journal.
Emerging Infectious Diseases (EID) is an open-access, peer-reviewed journal published by the Centers for Disease Control and Prevention (CDC). EID is a public domain journal and covers global instances of new and reemerging infectious diseases, putting greater emphasis on disease emergence, prevention, control, and elimination. According to Journal Citation Reports, the journal's 2022 impact factor is 11.8. The journal also has a 2023 Google Scholar h5-index score of 106, ranking it 2nd in the epidemiology category and 4th in the communicable diseases category.
David J. Lipman is an American biologist who from 1989 to 2017 was the director of the National Center for Biotechnology Information (NCBI) at the National Institutes of Health. NCBI is the home of GenBank, the U.S. node of the International Sequence Database Consortium, and PubMed, one of the most heavily used sites in the world for the search and retrieval of biomedical information. Lipman is one of the original authors of the BLAST sequence alignment program, and a respected figure in bioinformatics. In 2017, he left NCBI and became Chief Science Officer at Impossible Foods.
The Web of Science is a paid-access platform that provides access to multiple databases that provide reference and citation data from academic journals, conference proceedings, and other documents in various academic disciplines. Until 1997, it was originally produced by the Institute for Scientific Information. It is currently owned by Clarivate.
PeerJ is an open access peer-reviewed scientific mega journal covering research in the biological and medical sciences. It is published by a company of the same name that was co-founded by CEO Jason Hoyt and publisher Peter Binfield, with initial financial backing of US$950,000 from O'Reilly Media's O'Reilly AlphaTech Ventures, and later funding from Sage Publishing.
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.”
OpenCitations is a project aiming to publish open bibliographic citation information in RDF. It produces the "OpenCitations Corpus" citation database in the process.
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.
medRxiv is an Internet site distributing unpublished eprints about health sciences. It distributes complete but unpublished manuscripts in the areas of medicine, clinical research, and related health sciences without charge to the reader. Such manuscripts have yet to undergo peer review and the site notes that preliminary status and that the manuscripts should not be considered for clinical application, nor relied upon for news reporting as established information.
The Western Journal of Emergency Medicine: Integrating Emergency Care with Population Health, (WestJEM) is a bimonthly peer-reviewed, fully open access medical journal.
Clarivate Plc is a British-American publicly traded analytics company that operates a collection of subscription-based services, in the areas of bibliometrics and scientometrics; business / market intelligence, and competitive profiling for pharmacy and biotech, patents, and regulatory compliance; trademark protection, and domain and brand protection. In the academy and the scientific community, Clarivate is known for being the company which calculates the impact factor, using data from its Web of Science product family, that also includes services/applications such as Publons, EndNote, EndNote Click, and ScholarOne. Its other product families are Cortellis, DRG, CPA Global, Derwent, MarkMonitor, CompuMark, and Darts-ip, and also the various ProQuest products and services.
Endocrine Connections is a society-owned, monthly, peer-reviewed, open access academic journal. It covers endocrinology with a focus on basic, clinical and translational research and reviews in all areas of endocrinology, including papers that deal with non-classical tissues as source or targets of hormones and endocrine papers that have relevance to endocrine-related and intersecting disciplines and the wider biomedical community. It is jointly owned by the European Society of Endocrinology and the Society for Endocrinology. The editor-in-chief is Professor Adrian Clark, who succeeded Professor Josef Köhrle in 2021. According to the Journal Citation Reports, the journal has a 2022 impact factor of 2.9. The journal has been published by Bioscientifica since 2012.
