BioNumbers - The Database of Useful Biological Numbers

Images from the History of Medicine (IHM) Images from the History of Medicine (IHM) provides access to over 70,000 images in the collections of the History of Medicine Division (HMD) of the U.S National Library of Medicine (NLM). The collection includes portraits, photographs, caricatures, genre scenes, posters, and graphic art illustrating the social and historical aspects of medicine dated from the 15th to 21st century. The records from the Images from the History of Medicine database are also searchable in LocatorPlus. This database assists users in finding and viewing visual material for private study, scholarship, and research. This site contains some materials that may be protected by United States or foreign copyright laws. It is the users' responsibility to determine compliance with the law when reproducing, transmitting, or distributing images found in IHM.

Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life.
