Yahoo! has introduced several new Search features, including expert picks and "cool site" results, the availability of PDF files, and file type markers.

"Cool sites" selected by Yahoo! editors and marked with sunglasses have long been a hallmark of the directory.  Now they're available in search results also.

Yahoo! editors are now listing PDF files in the directory, in addition to what has traditionally been just a home page or several key subpages for
an entire web site.  These are labeled with a red (PDF) symbol immediately to the right of a title, and appear both in directory listings and search
results.

Yahoo! now identifies file types from its Google-powered index with the addition of a simple marker to denote Word, Excel, PDF or other file types.
