Target: Calculating the age of a collection

[Charlotte Snyder <csnyder@MAIL.BCPL.LIB.MD.US>]

Dear Friends:

I am gathering ammunition for my budget request for next year. I'm sure
I've seen a method to calculate the age of a collection, but I can't find
it in the archives. I think it involved checking the age of every _th
book, or the age of certain hundreds. I am not automated, so can't use the
one method I did find of asking the circ system. Thanks for any help you
can offer.

Charlotte
