How to handle corporate interlibrary loan requests that come to the reference desk

Sometimes, corporate borrowers call the reference desk to arrange for an interlibrary loan.
I asked Ester Ramos, and these are suggested procedures:

You can check the availability of the item on CUNY+.
Or, you can refer the caller to the circulation department, 646-312-1660.
In any event, the caller should submit the request on an approved ALA interlibrary loan form. If they don't already have a form, links to the forms are at:
http://www.ala.org/ala/rusa/rusaprotools/referenceguide/interlibrary.cfm#forms.
The form should be faxed to 646-312-1661. (A fax number at circulation)

Cost is discussed at circulation.
