What percentage of the journals or articles needed by the faculty at your university are unavailable except by interlibrary loan or private emails to lucky colleagues elsewhere? Let's call this the "ullage" of the library, after the word for the empty space at the top of a wine bottle. The ullage of a library is the gap between what is directly available and what is needed.
