The Perkins Library has three 3-M self-checkout machines:

• one located near the main Perkins Circulation desk
• one just inside the Bostock entrance
• a third just inside the Perkins gateway entrance.  Borrowers with a Duke photo ID or any Duke library card may check out any barcoded item at these stations.

How to use the self-checkout machines:

• The monitor display should prompt you to place the barcode of your library card underneath the laser scanner line. 
• If you have a valid account, you are next prompted to place the barcode of the first item you wish to check out under the scanner. 
• If the barcode is successfully read, the screen display prompts you to place the spine of the book against the cradle of the machine.  A little ping will give you an audio prompt that the transaction has been successful. 
• If you have more books to check out, push the Continue button and place the barcode of the next item under the scanner. 
• Once the barcodes on all items have been successfully read, touch the Done button on the screen.  This will print out a receipt for the transaction, listing all items checked out, along with their due dates.

Frequently Encountered Problems:

• If your borrower's card is defective or damaged it may not be properly read and should be replaced. You can get a new University ID at the Duke Card Office at 100 West Union Building.  If you are not a student, faculty, or staff member at Duke, you may get a replacement library card at the Perkins Circulation desk.
• If an item does not have a barcode on the outside back cover, it must be checked out at the Circulation Desk.
  
• The self-check system will also alert users to problems in reading book barcodes and will direct them to take such items to a circulation desk.  Staff at the Bostock help desk or at the Perkins Circulation desk can assist you in these cases.
