Interlibrary Loans & Call Slips

To place an ILL request, patrons can access the ILL form on the Library website under "Services" and "Interlibrary Loan (ILL)."

How long does it take?

  • Usually 1-5 business days for articles and book chapters.
  • Usually 3-10 business days for books and other physical items.
  • It may take longer to obtain some items.
  • We cannot guarantee that every request will be able to be filled.

How long do loans last?

  • Articles and book chapters are sent via email and do not need to be returned.
  • Loan periods for physical items are set by supplying libraries and usually last 2-6 weeks.
  • If your item indicates that renewal requests are allowed, email before the due date.
  • An item recalled by its supplying library must be returned to us immediately.

How to place a Call Slip request:

1) Find the book you want to request in the Library catalog and click "View Catalog Record."





2) You will be directed to another website. Click "Make a Request" on the right side of the screen.

3) You can login to your (or the patron's) account by selecting either the "Barcode" or "Institution ID" fields and then inputting your or the patron's last name. Note: "Barcode" refers to the number at the very bottom of the patron's WIT ID and "Institution ID" refers to their W number (see picture below).








4) After logging in, make sure you select "Wentworth Circulation Desk" for the "Pick Up At:" location. Only select another institution if the patron would like the book delivered somewhere besides the Schumann Library.


5) Click Submit and confirm that the Call Slip went through via the next screen. The patron will receive an e-mail as soon as the Call Slip request arrives to its designated location.
