Materials Platform for Data Science (MPDS) "Online materials database (known as PAULING FILE project) with nearly 2 million entries: physical properties, crystal structures, phase diagrams, available via API, ready for modern data-intensive applications. The source of these entries are about 300,000 peer-reviewed publications in materials science, processed during the last 16 years by an international team of PhD editors. The results are presented online with a quick search interface. The basic access is provided for free. "
MatWeb "MatWeb's searchable database of material properties includes data sheets of thermoplastic and thermoset polymers such as ABS, nylon, polycarbonate, polyester, polyethylene and polypropylene; metals such as aluminum, cobalt, copper, lead, magnesium, nickel, steel, superalloys, titanium and zinc alloys; ceramics; plus semiconductors, fibers, and other engineering materials."
Media History Digital Library "We are a non-profit initiative dedicated to digitizing collections of classic media periodicals that belong in the public domain for full public access. The project is supported by owners of materials who loan them for scanning, and donors who contribute funds to cover the cost of scanning. We have currently scanned over 2 million pages, and that number is growing."
MedKknow Open access to 377 medical and science journals.
MERLOT "MERLOT is a curated collection of free and open online teaching, learning, and faculty development services contributed and used by an international education community."
MET Collection "You are welcome to use images of artworks in The Met collection that the Museum believes to be in the public domain, or those to which the Museum waives any copyright it might have, for any purpose, including commercial and noncommercial use, free of charge and without requiring permission from the Museum." Over 450,000 images available.
Microstructure Database "Here you will find a collection of atomic microstructures that have been built by the atomic modeling community. Feel free to download any of these and use them in your own scientific explorations.The focus of this cyberinfrastructure is to advance the field of atomic-scale modeling of materials by acting as a forum for disseminating new atomistic scale methodologies, educating non-experts and the next generation of computational materials scientists, and serving as a bridge between the atomistic and complementary (electronic structure, mesoscale) modeling communities.
