Guide to Using OCLC WorldCat

What is WorldCat? 

WorldCat is a database produced and maintained by OCLC (Online Computer Library Center in Dublin, Ohio).  It is the world’s largest and most comprehensive catalog with more than 94 million bibliographic records.  

Why use WorldCat?

Can’t find what you’re looking for in the Yavapai Library Network catalog?  You can search WorldCat and request that item online.  Your request will automatically be sent to our Interlibrary Loan Department to be processed.  The library will call you when your item is ready to be picked up at the reference desk.  (There is a $3.00 fee for books and materials that come from outside of the State of Arizona and a $1.00 fee for articles.)

How to access WorldCat

From the library's homepage, go to Find Articles & More and click on the Databases A-Z page.  Select WorldCat from the alphabetical list of databases.

Enter your 14-digit library card number.

Constructing your search

WorldCat will automatically open to the Advanced Search screen:

Type a word or phrase in one or more of the search boxes.  If you know the exact title or author, then pull down the menu by clicking on the arrow to the right of “Keyword” and select the appropriate category. 

You can limit your search further by checking the box for a specific material type, such as Books, Computer Files, Sound Recordings, or Visual Materials (for videos and DVDs).

(Tip:  Do not use the “Back” button on your Internet browser.  Instead, use the tabs at the top of the FirstSearch screen, such as “Searching” to navigate back and forth). 

Once you have found the correct record for the item you want, click on the title to access the detailed record.  To request the item, click on the black ILL button  at the top, left hand side of the page.  At the next screen, simply type in your first name, last name and telephone number, then click “Submit”.  A message will appear at the top of the screen stating, “Your ILL request was sent successfully.”
