SIMPLE SEARCH, which is the simplest method of searching catalogs just enter any keyword, whether it contains titles, author(s) names, or subjects.
ADVANCED SEARCH, lets you define keywords in more specific fields. If you know the exact title of the book you're looking for just type the title in the Title field and the system will limit its search to Title fields only. The Location field will let you narrow search results by specific location so only collection that exists in the selected location get fetched by the system.
