What is my library barcode and pin?

Your library barcode is the 14-digit number printed on your McMaster ID card.

This barcode number and pin (which you set the first time you log in) allow you to log into your library account to renew materials or request holds and recalls.

You will also need your barcode number when registering for RACER, the tool that allows you to request materials McMaster does not own from other libraries.
