In thinking through the options for placing the searchbox for WorldCat Local on our website, I'm inclined to argue for a single search box on the homepage rather than the somewhat confusing tabbed box that we have now. After all, WCL should get us to our "catalog" content, journal titles, and provide a general article search.
The problem with offering a single search box to patrons is that we miss content that they might want from a library site search: links to research database, course reserves, library hours, librarian contact info, etc.
WorldCat Local might be improved if it had the option to integrate Google style "OneBoxes" in its results display. A little box off to the side might highlight items like course reserves or matches from a site search.
I have a feeling, I'll probably lose the argument regarding a single search box on our website. After all, even Google offers users multiple silos of content to search (Books, Web, Blogs, News, etc.).
