This site is powered by Siderean Software's Seamark faceted navigation engine, a powerful new approach to website content searching. These new tools make it much easier to find data buried within complex databases.
Here's a quick overview of the navigation interface.
You can always search the traditional way by using the text search box at the upper right.

The pane along the left of the archive page, shown to the left (reduced) provides a new way to explore the data. All of the entries in the database have been classified in a series of major categories, called Facets, and then by subcategories within the Facets, labeled Topics.
The categorization is hierarchical. For example, within the topic "Birth Defect" (in the Human health condition facet), there are additional subcategories including "Cleft palate/lip," "Neural tube," urogenital," etc., which you will see when you click on "Birth Defect."
A note about categorization: Our editors review the category assignments made by our indexing engine, but sometimes you will encounter articles that don't have all the appropriate category assignments. Using the text searches may be helpful in finding some articles. Feedback is always welcome.
