ARTbibliographies Modern (ABM) provides full abstracts of journal articles, books, essays, exhibition catalogs, PhD dissertations, and exhibition reviews on all forms of modern and contemporary art, with approximately 12-13,000 new entries being added each year. Entries date back as far as the late 1960s. ABM is the premier source of information on modern and contemporary arts dating from the late 19th century onwards, and including photography since its invention. It includes abstracts of English and foreign-language material on famous and lesser-known artists, movements, and trends. The coverage of ABM is wide-ranging and includes performance art and installation works, video art, computer and electronic art, body art, graffiti, artists' books, theatre arts, conservation, crafts, ceramic and glass art, ethnic arts, graphic and museum design, fashion, and calligraphy, as well as traditional media including illustration, painting, printmaking, sculpture, and drawing.

The Bibliography of the History of Art (BHA) contains abstracts and indexes of current publications in the history of art, including scholarly journals, conferences, book, exhibition reviews, and exhibition catalogues. The records consist of bibliographic citations, abstracts, and indexing. Note that the database search includes BHA, covering 1990-2007, the International Bibliography of Art (IBA), covering the years 2008 and part of 2009, and the Répertoire de la litterature de l'art (RILA), one of the predecessors of BHA, with records that cover 1975–1989.

GeoReM is a Max Planck Institute database for reference materials of geological and environmental interest, such as rock powders, synthetic and natural glasses as well as mineral, isotopic, biological, river water and seawater reference materials. It contains published analytical data and compilation values (major and trace element concentrations and mass fractions, radiogenic and stable isotope ratios). GeoReM covers all important metadata about the analytical values such as uncertainty, analytical method and laboratory. Sample information and references are also included. GeoReM contains almost 3,400 reference materials, about 46,200 analyses from almost 10,000 papers, and preferred analytical values (State: November 2017).

The database GEOROC is maintained by the Geoscience Centre at Göttingen University. The database is a comprehensive collection of published analyses of volcanic rocks and mantle xenoliths. It contains major and trace element concentrations, radiogenic and nonradiogenic isotope ratios as well as analytical ages for whole rocks, glasses, minerals and inclusions. Samples come from 11 different geological settings. Metadata include, among others, geographic location with latitude and longitude, rock class and rock type, alteration grade, analytical method, laboratory, reference materials and references.

GeoScienceWorld (GSW) is a nonprofit collaborative and comprehensive resource for research and communications in the earth sciences, which is built on a core database of peer-reviewed journals and is integrated with the GeoRef index. The platforms offers a single point of access to more than 40 full text scholarly journals from leading geoscientific organizations, plus specialized searching capabilities and links to millions of relevant resources hosted elsewhere on the Web. Though access to current volumes is no longer licensed, perpetual access rights have been granted to the content published until August 2018.

The International Bibliography of Art (IBA) is the successor to the Bibliography of the History of Art (BHA), and retains the editorial policies which made BHA one of the most trusted and frequently consulted sources in the field. The database includes records created by the Getty Research Institute in 2008-09, with new records created by ProQuest using the same thesaurus and authority files. The database will grow by 18,000 records per year, ensuring unbroken coverage of journals that were indexed in BHA and IBA prior to 2010. The initial data set created by the Getty Research Institute in 2008-2009 covers scholarship up to 2009, including retrospective records for material published in previous years, and in some cases the new ProQuest indexing will also cover retrospective years in order to fill gaps in coverage. Publications covered include at least 500 core journals, with an emphasis on specialist and rare titles that are not covered by other indexes, plus detailed coverage of monographs, essay collections, conference proceedings and exhibition catalogues. We aim for at least 60% of the content to be in languages other than English (primarily German, French, Italian and Spanish), with a proportion of this indexing provided by national art libraries and freelance indexers from around the world.

The OSF Preprints search combines records from various preprint repositories, including arXiv, bioRxiv, Cogprints, PeerJ, PsyArXiv, RePEc and SocArXiv.

This historic journal index enables the simultaneous search in millions of citations for articles published in the arts, humanities and social sciences, across more than 300 years. It enables researchers quickly and comprehensively to identify articles relevant to their field of study and reduces what could take years of research to a matter of minutes. Journals indexed span 37 key subject areas and multiple languages.

SciELO (Scientific Electronic Library Online) is a program of the Sao Paulo Research Foundation for the cooperative publishing of open access journals on the internet. Content includes regional journals from Latin American and the Caribbean as well as titles from Spain, Portugal and South Africa. The index covers approximately 650 titles (over 350 adding content to journals already covered in the Web of Science) and contains several million cited references.
