Michael Levine-Clark, Collections Librarian at the University of Denver has written an editorial for Collaborative Librarianship entitled *Whither ILL? Wither ILL: The Changing Nature of Resource Sharing for E-Books*.  He insists that  libraries are justifiable proud of interlibrary loan as a delivery system for print books but it is “not the right system at all for delivering e-books.”   Instead he says that “a short-term lease – a cost somewhere below the costs involved in traditional ILL – we could greatly improve efficiency and get the book to the user almost immediately.”  He also notes that “the major e-book vendors (EBL, ebrary, MyiLibrary, and NetLibrary) already offer these services or are considering them seriously.”
