Open access (OA) is a set of principles and a range of practices through which nominally copyrightable publications are delivered to readers free of access charges or other barriers. With open access strictly defined, or libre open access, barriers to copying or reuse are also reduced or removed by applying an open license for copyright, which regulates post-publication uses of the work.
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.
Reference management software, citation management software, or bibliographic management software is software that stores a database of bibliographic records and produces bibliographic citations (references) for those records, needed in scholarly research. Once a record has been stored, it can be used time and again in generating bibliographies, such as lists of references in scholarly books and articles. Modern reference management applications can usually be integrated with word processors so that a reference list in one of the many different bibliographic formats required by publishers and scholarly journals is produced automatically as an article is written, reducing the risk that a cited source is not included in the reference list. They will also have a facility for importing bibliographic records from bibliographic databases.
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.
Open scientific data or open research data is a type of open data focused on publishing observations and results of scientific activities available for anyone to analyze and reuse. A major purpose of the drive for open data is to allow the verification of scientific claims, by allowing others to look at the reproducibility of results, and to allow data from many sources to be integrated to give new knowledge.
Frontiers Media SA is a publisher of peer-reviewed, open access, scientific journals currently active in science, technology, and medicine. It was founded in 2007 by Kamila and Henry Markram.

PeerJ is an open access peer-reviewed scientific mega journal covering research in the biological and medical sciences. It officially launched in June 2012, started accepting submissions on December 3, 2012, and published its first articles on February 12, 2013.
Predatory publishing, also write-only publishing or deceptive publishing, is an exploitative academic publishing business model, where the journal or publisher prioritizes self-interest at the expense of scholarship. It is characterized by misleading information, deviates from the standard peer-review process, is highly non-transparent, and often utilizes aggressive solicitation practices.
Beall's List was a prominent list of predatory open-access publishers that was maintained by University of Colorado librarian Jeffrey Beall on his blog Scholarly Open Access. The list aimed to document open-access publishers who did not perform real peer review, effectively publishing any article as long as the authors pay the article processing charge. Originally started as a personal endeavor in 2008, Beall's List became a widely followed piece of work by the mid-2010s. The list was used by scientists to identify exploitative publishers and detect publisher spam.

Serbian Citation Index is a combination of an online multidisciplinary bibliographic database, a national citation index, an Open Access full-text journal repository and an electronic publishing platform. It is produced and maintained by the Centre for Evaluation in Education and Science (CEON/CEES), based in Belgrade, Serbia. In July 2017, it indexed 230 Serbian scholarly journals in all areas of science and contained more than 80,000 bibliographic records and more than one million bibliographic references.
Open access to scholarly communication in Germany has evolved rapidly since the early 2000s. Publishers Beilstein-Institut, Copernicus Publications, De Gruyter, Knowledge Unlatched, Leibniz Institute for Psychology Information, ScienceOpen, Springer Nature, and Universitätsverlag Göttingen belong to the international Open Access Scholarly Publishers Association.
Open access to scholarly communication in Austria has developed in the 2010s largely through government initiatives. The Austrian Science Fund and Universities Austria launched the "Open Access Netzwerk Austria" in 2012 to coordinate country-wide efforts. The "E-Infrastructures Austria" project began in 2014 to develop repositories. The international advocacy effort "OpenscienceASAP – Open Science as a Practice" is based in Austria.
Open access scholarly communication of Norway can be searched via the Norwegian Open Research Archive (NORA). "A national repository consortium, BIBSYS Brage, operates shared electronic publishing system on behalf of 56 institutions." Cappelen Damm Akademisk, Nordic Open Access Scholarly Publishing, University of Tromsø, and Universitetsforlaget belong to the Open Access Scholarly Publishers Association. Norwegian signatories to the international "Open Access 2020" campaign, launched in 2016, include CRIStin, Norsk institutt for bioøkonomi, Norwegian Institute of Palaeography and Historical Philology, Norwegian University of Science and Technology, Oslo and Akershus University College of Applied Sciences, University of Tromsø, University of Bergen, University of Oslo, and Wikimedia Norge.
Open access to scholarly communication in Sweden is relatively widespread. In 2010 the Swedish Research Council began requiring its grantees to make research results available in open access form. Lund University Libraries and Stockholm University Press belong to the international Open Access Scholarly Publishers Association.
Diamond open access refers to academic texts published/distributed/preserved with no fees to either reader or author. Alternative labels include platinum open access, non-commercial open access, cooperative open access or, more recently, open access commons. While these terms were first coined in the 2000s and the 2010s, they have been retroactively applied to a variety of structures and forms of publishing, from subsidized university publishers to volunteer-run cooperatives that existed in prior decades.
SciPost is a non-profit foundation dedicated to developing, implementing and maintaining innovative forms of electronic scientific communication and publishing. It is notable for operating the scipost.org open-access scientific publishing portal.
