CiteSeerx is a public search engine and digital library for scientific and academic papers, primarily in the fields of computer and information science. CiteSeer is considered as a predecessor of academic search tools such as Google Scholar and Microsoft Academic Search. CiteSeer-like engines and archives usually only harvest documents from publicly available websites and do not crawl publisher websites. For this reason, authors whose documents are freely available are more likely to be represented in the index.
In library and archival science, digital preservation is a formal endeavor to ensure that digital information of continuing value remains accessible and usable. It involves planning, resource allocation, and application of preservation methods and technologies, and it combines policies, strategies and actions to ensure access to reformatted and "born-digital" content, regardless of the challenges of media failure and technological change. The goal of digital preservation is the accurate rendering of authenticated content over time. The Association for Library Collections and Technical Services Preservation and Reformatting Section of the American Library Association, defined digital preservation as combination of "policies, strategies and actions that ensure access to digital content over time." According to the Harrod's Librarian Glossary, digital preservation is the method of keeping digital material alive so that they remain usable as technological advances render original hardware and software specification obsolete.
An institutional repository is an archive for collecting, preserving, and disseminating digital copies of the intellectual output of an institution, particularly a research institution.
The Cornell University Library is the library system of Cornell University. As of 2014, it holds over 8 million printed volumes and over a million ebooks. More than 90 percent of its current 120,000 periodical titles are available online. It has 8.5 million microfilms and microfiches, more than 71,000 cubic feet (2,000 m3) of manuscripts, and close to 500,000 other materials, including motion pictures, DVDs, sound recordings, and computer files in its collections, in addition to extensive digital resources and the University Archives. It is the sixteenth largest library in North America, ranked by number of volumes held.
Fedora is a digital asset management (DAM) content repository architecture upon which institutional repositories, digital archives, and digital library systems might be built. Fedora is the underlying architecture for a digital repository, and is not a complete management, indexing, discovery, and delivery application. It is a modular architecture built on the principle that interoperability and extensibility are best achieved by the integration of data, interfaces, and mechanisms as clearly defined modules.
The California Digital Library (CDL) was founded by the University of California in 1997. Under the leadership of then UC President Richard C. Atkinson, the CDL’s original mission was to forge a better system for scholarly information management and improved support for teaching and research. In collaboration with the ten University of California Libraries and other partners, CDL assembled one of the world's largest digital research libraries. CDL facilitates the licensing of online materials and develops shared services used throughout the UC system. Building on the foundations of the Melvyl Catalog, CDL has developed one of the largest online library catalogs in the country and works in partnership with the UC campuses to bring the treasures of California's libraries, museums, and cultural heritage organizations to the world. CDL continues to explore how services such as digital curation, scholarly publishing, archiving and preservation support research throughout the information lifecycle.
Digital Commons is a commercial, hosted institutional repository platform owned by RELX Group. This hosted service, licensed by bepress, is used by over 500 academic institutions, healthcare centers, public libraries, and research centers to showcase their scholarly output and special collections.
The digital repository audit method based on risk assessment (DRAMBORA) is a methodology and associated software-based toolkit developed by Digital Curation Centre (DCC) and DigitalPreservationEurope (DPE) to support the assessment of digital preservation repositories. Documentation for the DRAMBORA toolkit is available at the Digital Curation Centre's and DigitalPreservationEurope's DRAMBORA Interactive page.
BASE is a multi-disciplinary search engine to scholarly internet resources, created by Bielefeld University Library in Bielefeld, Germany. It is based on free and open-source software such as Apache Solr and VuFind. It harvests OAI metadata from institutional repositories and other academic digital libraries that implement the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), and then normalizes and indexes the data for searching. In addition to OAI metadata, the library indexes selected web sites and local data collections, all of which can be searched via a single search interface.
PREservation Metadata: Implementation Strategies (PREMIS) is the de facto digital preservation metadata standard.
HathiTrust Digital Library is a large-scale collaborative repository of digital content from research libraries including content digitized via Google Books and the Internet Archive digitization initiatives, as well as content digitized locally by libraries.
A digital library, also called an online library, an internet library, a digital repository, or a digital collection is an online database of digital objects that can include text, still images, audio, video, digital documents, or other digital media formats or a library accessible through the internet. Objects can consist of digitized content like print or photographs, as well as originally produced digital content like word processor files or social media posts. In addition to storing content, digital libraries provide means for organizing, searching, and retrieving the content contained in the collection.
An open-access repository or open archive is a digital platform that holds research output and provides free, immediate and permanent access to research results for anyone to use, download and distribute. To facilitate open access such repositories must be interoperable according to the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Search engines harvest the content of open access repositories, constructing a database of worldwide, free of charge available research.
Open access to scholarly communication in South Africa occurs online via journals, repositories, and a variety of other tools and platforms. Compared to other African nations, open access in South Africa has grown quickly in recent years.
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.
In Belgium, open access to scholarly communication accelerated after 2007 when the University of Liège adopted its first open-access mandate. The "Brussels Declaration" for open access was signed by officials in 2012.
In January 2008, Russian, Belarusian, and Ukrainian academics issued the "Belgorod Declaration" in support of open access to scientific and cultural knowledge. Russian supporters of the international "Open Access 2020" campaign, launched in 2016, include Belgorod State University, National Electronic Information Consortium (NEICON), and Webpublishers Association.
In Ukraine, a 2007 law requires open access publishing of research created through public funding. In January 2008, Ukrainian, Belarusian, and Russian academics issued the "Belgorod Declaration on open access to scientific knowledge and cultural heritage." Ukrainian academics issued another statement in June 2009 in support of open access.
