Browse Nodes and Items

Browse nodes are categories in which items are organized. A single node can have many items associated with it, as shown in the following example:

In this example, six items (Harry Potter book titles) are associated with the browse node: Harry Potter Books. This node is a leaf node and a child of the Books parent node. Many items can be associated with a single browse node. The name of the browse node describes what the items have in common.

A single item can also belong to more than one browse node. For example, a book can belong to the Books and Top Sellers browse nodes:

When a book is removed from the top sellers list, the book is removed from its association with the Top Sellers browse node. The association between items and browse nodes is dynamic.

Browse nodes are created and deleted according to item demand. Items associated with the browse node, Top Sellers, change frequently according to sales. For example, when a new group of books sells quickly, a node is created for it. When the sales decline, the node can be deleted. Some browse nodes exist for a short time.

Other browse nodes are permanent, such as the top-level nodes Books and Apparel. So are the browse nodes associated with cities, as shown in the following table:
