The National Academies Press

The National Academies Press (NAP) was created by the National Academy of Sciences to publish the reports of the National Academies of Sciences, Engineering and Medicine, operating under a charter granted by the Congress of the United States. The NAP publishes more than 200 books a year on a wide range of topics in science, engineering, and medicine, providing authoritative information on important matters in science and health policy. The institutions served by the NAP are unique in their ability to attract leading experts in many fields to join panels and committees charged with providing policy advice on some of the nation’s most pressing scientific, technical, and health-related issues.

The Open Access Directory (OAD)

The Open Access Directory (OAD) is a compendium of simple factual lists about open access (OA) to science and scholarship, maintained by the OA community at large. By bringing many OA-related lists together in one place, OAD makes it easier for everyone to discover them, use them for reference, and update them. The easier they are to maintain and discover, the more effectively they can spread useful, accurate information about OA. To see what we have, browse the table of contents below, browse the table of categories, or use the search box in near the upper right corner. To help the cause, just register and start editing. If you have any questions, see our help section or drop us a line.

Listing of Open Access DataBases (LOADB)

A large number of Government agencies, research institutions and academic institutions across the world create databases in various fields of science and technology. Today, many of these databases are available free on the World Wide Web through individual portals or websites of the respective organizations. Unfortunately, these databases are not separately classified. So a user upon searching on the Internet gets thousands and millions of hits and keeps on clicking the websites to find if there is a relevant database associated with any of the websites. It is a time- consuming process and due to the limitation of search engines, only a hundred sites can be checked at any given point in time. It leads to poor awareness and accessibility of freely available databases.

Registry of Open Access Repository

OceanDocs is supported by the Intergovernmental Oceanographic Commission (IOC) to collect, preserve and facilitate discovery and access to all research output from members of the ocean research and observation community and specifically their Ocean Data and Information Networks (ODINS). It is one of a number of complementary thematic digital marine and aquatic repositories including the Aquatic Commons, which is supported by the International Association of Aquatic and Marine Science Libraries and Information Centers (IAMSLIC).

50 partners, from all EU countries, and beyond, will collaborate to work on this large-scale initiative that aims to promote open scholarship and substantially improve the discoverability and reusability of research publications and data. The initiative brings together professionals from research libraries, open scholarship organisations, national e-Infrastructure and data experts, IT and legal researchers, showcasing the truly collaborative nature of this pan-European endeavor. A network of people, represented by the National Open Access Desks (NOADs), will organise activities to collect H2020 project outputs, and support research data management. Backing this vast outreach, is the OpenAIRE platform, the technical infrastructure that is vital for pulling together and interconnecting the large-scale collections of research outputs across Europe. The project will create workflows and services on top of this valuable repository content, which will enable an interoperable network of repositories (via the adoption of common guidelines), and easy upload into an all-purpose repository (via Zenodo).
