I to am interested in this subject as I am doing my master's thesis on 
the the turnover rate of a collection as it relates to its relative 
age.  If there is anyone out there who knows of studies done on 
determining the appropriate age of a collection as it relates to its 
category, I would appreciate that information very much.  My study 
will involve a number of public libraries, I am trying to determine if 
the most current collections are the ones with the highest circulation.
