Tips for ordering inter-library loans:
If you need more than one article from an issue of a journal, ask for the entire issue to be sent to you.
If you need more than one paper from the same volume of a conference (they are often published in several volumes) ask for the entire volume to be sent to you.
If you need more than a single chapter from within a book, ask for the whole book as a loan.
