At the College of William and Mary, we are just finishing up a $ 100,000
serials cancellation project (just yesterday, I mailed our cancellation
list to our major periodicals vendor).  Our serials budget is a little over
$ 820,000.
We are attempting to maintain a 60:40 serials-to-book ratio, or at least
within that ballpark.
The last serials cancellation that we had to do was about 3 years ago.  If
the Commonwealth of Virginia continues on its present financial course (a
graceful downward slide), we will most likely have to go through another
such project in 2 to 3 years.
