Okay, so what are the steps involved in finding a book?
Here's what you do:
Search the library catalog to find out if the library owns the book (or other item) you need
Write down its call number and note the collection as well (general collection, reference collection, Emirates collection, etc.)
Use this information to go to the correct shelf to find the item
Library catalogs may also include items found on the Web (electronic books, encyclopedias and dictionaries mostly). For these items, go to the online location by clicking on the URL provided.
