OneSearch is a service that allows patrons to search across multiple library sources and databases from a single search box. It extracts results from the library catalog, journal titles, databases, and other sources. To search for a book by title in OneSearch, users enter the title in the search box, select the title option, and refine the results to the catalog only. They then note the call number and help the patron locate the book by writing the call number on a bookmark, indicating the floor, and directing them to the book while pointing out help options.
