Semantic Scholar provides free, AI-driven search and discovery tools, and open resources for the global research community. We index over 200 million academic papers sourced from publisher partnerships, data providers, and web crawls. Semantic Scholar is a Research and Product Development team within the Allen Institute for AI building a better way to search and discover scientific knowledge. With Semantic Scholar, researchers can understand a paper at a glance. Our system extracts meaning and identifies connections from within papers, then surfaces these insights to help Scholars discover and understand research.

CORE provides access to the world’s largest collection of open access research papers, collecting and indexing research from repositories and journals. It is a not-for-profit service dedicated to the open access mission and one of the signatories of the Principles of Open Scholarly Infrastructures POSI.We serve the global network of repositories and journals increasing discoverability and preventing misuse of their content; making metadata records uniquely identifiable and resolvable with decentralised PIDs.

Arachne is an internet research tool for the Archaeologies and Altertumswissenschaft. It offers a means to access objects and their states and to search efficiently in hundreds of thousands of datasets. Arachne feeds from analogue and digital sources. Archival material is often not adequately documented and in danger of being destroyed over time; Arachne is actively digitizing and documenting these materials. On the other hand, there is an ever growing amount of born-digital images and object data. By employing Semantic Web strategies, Arachne provides a low-threshold structure for these data. All digitized images and textual data in Arachne are preserved for the long term and available online.

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.

The mission of ERIC is to provide a comprehensive, easy-to-use, searchable, Internet-based bibliographic and full-text database of education research and information for educators, researchers, and the general public. Education research and information are essential to improving teaching, learning, and educational decision-making. ERIC provides access to 1.5 million bibliographic records (citations, abstracts, and other pertinent data) of journal articles and other education-related materials, with hundreds of new records added every week. A key component of ERIC is its collection of grey literature in education, which is largely available in full text in Adobe PDF format. 

The SAO/NASA Astrophysics Data System (ADS) is a digital library portal for researchers in astronomy and physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic collections containing more than 15 million records covering publications in astronomy and astrophysics, physics, and general science, including all arXiv e-prints. Abstracts and full-text of major astronomy and physics publications are indexed and searchable through the new ADS modern search form as well as a classic search form. A browsable paper form is also available

BASE is one of the world's most voluminous search engines especially for academic web resources. BASE provides more than 300 million documents from more than 10,000 content providers. You can access the full texts of about 60% of the indexed documents for free (Open Access). BASE is operated by Bielefeld University Library. We are indexing the metadata of all kinds of academically relevant resources – journals, institutional repositories, digital collections etc. – which provide an OAI interface and use OAI-PMH for providing their contents (see our Golden Rules for Repository Managers).

Crossref makes research objects easy to find, cite, link, assess, and reuse. Crossref a not-for-profit membership organization that exists to make scholarly communications better. They rally the community; tag and share metadata; run an open infrastructure; play with technology; and make tools and services—all to help put research in context.

DBLP is a computer science bibliography website. Starting in 1993 at Universität Trier in Germany, it grew from a small collection of HTML files and became an organization hosting a database and logic programming bibliography site. Since November 2018, DBLP is a branch of Schloss Dagstuhl – Leibniz-Zentrum für Informatik (LZI).DBLP listed more than 5.4 million journal articles, conference papers, and other publications on computer science in December 2020, up from about 14,000 in 1995 and 3.66 million in July 2016.All important journals on computer science are tracked. Proceedings papers of many conferences are also tracked. It is mirrored at three sites across the Internet.

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.
