The method of claim 82, wherein the items comprise both file items and non-file items. 89. The method of claim 88, wherein the non-file items comprise at least one of contacts or e-mails. 90. The method of claim 82, further comprising providing a virtual address bar user interface control for selecting items accessible to a computer system for display, the virtual address bar comprising: a plurality of interactive segments, wherein each interactive segment corresponds to a filter for selecting items for display. 91. In a computer system with a display and a memory for storing items, the items being of a plurality of different types, a method for presenting libraries of the items, comprising: providing libraries for containing items of similar types; providing a similar set of UI features for each of the libraries, wherein the set of UI features includes a control for modifying metadata of one of the items that is displayed in response to a user hover input, and wherein the set UI features further includes a control that displays a time-rotating sample of a plurality of metadata associated with at least some of the items; and a virtual address bar method for providing a virtual path to items stored in a computer file system using a virtual address bar, the virtual address bar method comprising: displaying a virtual address bar operable to include a first interactive segment, wherein the first interactive segment references items on the computer file system according to a corresponding filter for selecting items; and adding one or more additional interactive segment to the virtual address bar, wherein each additional interactive segment further restricts the items referenced by the preceding interactive segments; wherein the first interactive segment and the one or more additional interactive segments comprise a virtual path. 92. The method of claim 91, wherein the different types comprise at least two of documents, images and music. 93. The method of claim 91, wherein the similar set of UI features includes a feature for creating new categories. 94. The method of claim 91, wherein the similar set of UI features includes a feature for altering a way that the items are displayed. 95. The method of claim 91, wherein in addition to containing items of similar types, the libraries may also contain items of different types. 96. The method of claim 91, further comprising providing a shell browser, the shell browser comprising: a window which displays a group of items, wherein the window also displays metadata values associated with one or more of the displayed items; and an edit control which permits user modification of at least a portion of the metadata values displayed in the window. 97. The method of claim 91, further comprising a previewer method for enabling the use of third party previewers in a shell browser which supports multiple item types, the previewer method comprising: providing a shell browser having a default previewer for the multiple item types; and providing an extensibility mechanism which enables a third party to develop an alternative previewer for at least one of the multiple item types. 98. The method of claim 91, further comprising providing a shell browser configured to display a plurality of items representing multiple item types, the shell browser comprising: a default previewer which provides a standard level of functionality for multiple item types; and an extensibility mechanism which enables functionality beyond the standard level provided by the default previewer for one or more of the multiple item types. 99. The method of claim 91, further comprising providing a virtual address bar user interface control for selecting items accessible to a computer system for display, the virtual address bar comprising: a plurality of interactive segments, wherein each interactive segment corresponds to a filter for selecting items for display. 100. The method of claim 91, further comprising a method of filtering items, the method of filtering items comprising: providing a plurality of display objects on the display that each represent one or more items; filtering the items represented by the display objects based on a filter term; and modifying the display objects that are provided on the display so as to represent the items that remain after the filtering of the items. 101. The method of claim 91, further comprising a method for displaying items, the method for displaying items comprising: defining a scope of the physical memory locations from which items are to be drawn, the scope comprising a present computer memory and at least one other physical location; receiving a query, and in response to the query, drawing items from the physical locations as defined in the scope; and presenting the items drawn from the query in a view on the display. 102. The method of claim 91, further comprising a method for representing the items to a user, the method for representing the items to the user comprising: providing a database that allows both non-file items and file items to be searched by a query; receiving a query, and in response to the query drawing both non-file items and file items that match the query; and presenting both the non-file items and file items that match the query on the display.
