Birds of the World (BOW) is a powerful research database that brings together deep, scholarly content from celebrated works of ornithology with millions of bird observations from eBird and multimedia from the Macaulay Library into a single platform where biologists and birders can explore comprehensive life history information on birds. BOW content is written by ornithologists all over the world and was amassed from four major celebrated works of ornithology: Birds of North America, The Handbook of Birds of the World, Neotropical Birds, and Bird Families of the World.

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.

The Arabidopsis Information Resource (TAIR) maintains a database of genetic and molecular biology data for the model higher plant Arabidopsis thaliana. Data available from TAIR includes the complete genome sequence along with gene structure, gene product information, gene expression, DNA and seed stocks, genome maps, genetic and physical markers, publications, and information about the Arabidopsis research community. Gene product function data is updated every week from the latest published research literature and community data submissions. TAIR also provides extensive linkouts from our data pages to other Arabidopsis resources. The Arabidopsis Biological Resource Center at The Ohio State University collects, reproduces, preserves and distributes seed and DNA resources of Arabidopsis thaliana and related species. Stock information and ordering for the ABRC are fully integrated into TAIR.

Wiley Current Protocols contains a collection of updatable step-by-step, reproducible laboratory methods, covering a total of 20,000 protocols across 18 subjects in the life sciences. Each protocol is carefully selected by the editorial board members, written by experts, and rigorously edited to ensure repeated success.
