See "UNAVailable" in http://people.bu.edu/rbs/ADSM.QuickFacts
for basic information.
Basically, do the research: look back in your Activity Log for the records on
when they volumes turned that way and find the circumstances which caused it.
A gross cause is the volumes not being in the library, or being in the library
in such a manner that they cannot be served.
